COMPARE

RightRep vs MyNetDiary.
An honest look.

MyNetDiary (MyNetDiary Inc. — founded December 2005 in New Jersey, iPhone app August 2008, "one of the first calorie counters," still privately held and self-funded out of Boca Raton, Florida) is the old guard of this comparison family: "Since 2005, MyNetDiary has built nutrition tracking around one principle: the data has to be right." That principle is a staff-verified database of more than 2 million foods with up to 108 nutrients per entry, built on USDA and NCC research-grade sources, with a team that "reviews and updates 2,500-3,500 foods every day" — and more than 50 other apps license it. The free tier is the family's most generous: "No ads, no account required, no paywall tricks," free barcode scanning while MyFitnessPal paywalls theirs. Premium ($8.99/mo or $59.99/yr) adds "Advanced Autopilot, adaptive TDEE" and a GLP-1 Companion; Premium Plus ($99.99/yr) adds an AI Coach that "reads your food diary, weight trends, and nutrient gaps"; there is a separate PlateAI app (2025) and a lifetime $179.99 door on their site. The evidence stack is the family's strongest — four independent peer-reviewed studies, their own disclosed-authorship JMIR 2026, two university trials — and unusually it publishes the unfavorable results too. It earns 4.81★ across 167,290 US ratings (4.83★ on just 80 in Brazil, an English-only iOS listing by their own admission: "Currently available in English only"), 4.67★ · 117,241 ratings · 5M+ downloads on Play, and "Over 32 million registered users" by its own count. What it does not do, on any of its five store apps, is observe a movement: no camera, no pose, no rep counting, no GPS — exercise tracking is typed. RightRep is the other shape of coach: photograph the plate and the AI estimates calories, per-item macros and drinks, then prop the phone against your water bottle and the same camera measures the set — 33 body landmarks per frame on the device, a 0–100 score for every completed repetition — with GPS runs and race-goal plans around it, in six locales including Portuguese. Every MyNetDiary claim on this page is cited to MyNetDiary's own materials or named sources, and the places where MyNetDiary clearly wins are listed as plainly as the rest.

The two products

What each one is, in its own words — before the side-by-side.

📓

MyNetDiary

The verified-data calorie counter — "MyNetDiary is the calorie tracker you'll actually stick with: fast, accurate, and ad-free. Log meals in seconds with the free barcode scanner, Meal Scan (just photograph your plate), or quick search" (US App Store description). The tenure is real: founded December 2005, web app 2007, native iPhone app August 2008, "one of the first calorie counters," still private and self-funded. The database is the product: "more than 2 million foods with up to 108 nutrients per entry, built on USDA and NCC research-grade sources, the same databases used in clinical research," reviewed at "2,500-3,500 foods every day," and licensed by "more than 50 other apps and services." The free tier runs on a stated doctrine — "Free Means Free — No Ads, No Paywalls on Essentials" — free barcode, voice logging, full macro tracking, charts with "no chart caps," an Apple Watch app and widgets, no account required, no ads in any tier at all. Premium carries "Advanced Autopilot, adaptive TDEE" (calories and macros updated weekly from logged food, exercise and Trending Weight) and the GLP-1 Companion — "nutrition-first support for Ozempic, Wegovy, Mounjaro, Zepbound" with "protein targets and muscle protection while you lose weight"; Premium Plus layers the AI Coach ("Not a generic chatbot — it reads your food diary, weight trends, and nutrient gaps"); a Diabetes Tracker app has existed since 2012 and PlateAI shipped August 2025. The press is description-pinned: "Named the top weight loss app by Forbes Health (2025)," the New York Times calling it "simpler, quicker, and better-looking than the competition" — quoted here as marketing exhibits, not our measurement. 4.81★ across 167,290 US ratings, 4.67★ · 117,241 · 5M+ downloads on Play, "Over 32 million registered users" by their own count.

📱

RightRep

A live form coach with the camera pointed at both halves of training: photograph a meal and the AI estimates the name, calories, per-item macros and any drinks — in every locale we ship, no database search, no separate camera tier — or type a description instead. Then prop the phone against your water bottle and the same camera stack watches the set: 33 body landmarks per frame measured on the device, faults flagged joint-by-joint, spoken cues mid-rep, a 0–100 score for every completed repetition. Around it: protein-first macro targets with an adaptive calorie goal, a weekly AI nutrition review, GPS run/walk recording, race-goal training plans, hydration logging and coach chat. Live form checks, GPS runs and training plans are free forever; the AI features — meal estimates included — come with the 7-day free trial every account starts with, then Pro at $9.99/month or $99.99/year.

Side by side

The same eight questions, asked of each product.

Question	MyNetDiary	RightRep
What is the product built around?	The verified database and the diary — "the data has to be right" since December 2005, served by a staff that reviews 2,500–3,500 foods every day	The filmed workout and the photographed plate — one camera stack for the gym floor and the kitchen table
How does a meal get logged?	Free barcode scanner and quick search; voice logging free; Premium Meal Scan photographs the plate "matched against the staff-verified database"; Plus adds AI voice logging	Snap a photo — the AI returns a name, calorie total, per-item breakdown, macros and any drinks — or type a description; every locale we ship
What happens during a workout?	Nothing observes it — "exercise tracking" is typed entries across all five store apps; no camera, no rep counting, no GPS	The camera measures it — 33 body landmarks per frame on the device, faults flagged joint-by-joint, reps counted in-state
What adapts weekly?	"Advanced Autopilot, adaptive TDEE" — "estimates your actual energy expenditure from logged food, exercise, and Trending Weight and updates calories and macros weekly" (Premium)	The adaptive calorie goal from the user's logged energy balance, plus training-adaptive plans — the loop reads movement MyNetDiary never sees
How deep does the nutrition data go?	Up to 108 nutrients per entry over 2 million staff-verified foods — micronutrient depth conceded wholesale	Calories, protein/carbs/fat per item, hydration — macro depth today; the 108-nutrient grid is theirs, not ours
Evidence?	Four independent peer-reviewed studies, their own disclosed-authorship JMIR 2026, two university trials using it as a tool — the misses published on their own research page	Younger product; our evidence story is the docs-site plus the observability of the loop itself
Devices, languages & exit?	iPhone/iPad (iOS 17+ floor on all five current apps), Apple Watch app + widgets, Android, web; iOS "Currently available in English only" by their own admission — the Play listing is localized to Portuguese; CSV export via the web account	iOS, Android and a web PWA in six locales incl. pt-BR; Apple Watch and Wear OS companions un-gated; Apple Health / Health Connect export free
Price & free tier?	Free barcode, no ads, no account required; Premium $8.99/mo · $59.99/yr (IAP list tests $29.99/$39.99 variants) · Plus $14.99/mo · $99.99/yr · lifetime $179.99 site-only — BR R$ 28,90/mo · R$ 124,90/194,90/249,90, PlateAI from R$ 59,90/mo	Live form checks, GPS runs and training plans free forever; the AI features — meal estimates included — ride the 7-day free trial every account starts with, then Pro at $9.99/month or $99.99/year

MyNetDiary column per MyNetDiary's own listings, mynetdiary.com and their research page (sources below). RightRep column per shipped behavior — the features page documents each row.

Where RightRep wins

The honest case for our side — grounded in what the app does today.

🏋️

The movement half none of the five apps observes

Across MyNetDiary's entire store presence — the main app, the PRO relic, Carb Genius, PlateAI and Diabetes Tracker — no camera has ever checked a rep and no GPS has ever recorded a run: "exercise tracking" is typed entries, and the AI Coach reads a diary. RightRep measures the workout itself: 33 body landmarks per frame on the device, faults flagged joint-by-joint, a 0–100 score for every completed repetition, GPS run/walk recording and race-goal plans. The loop that adapts your calories can read what the workout actually was.

📱

One app, one ladder, both halves

MyNetDiary's store presence is five apps deep — main, PRO, Carb Genius, PlateAI, Diabetes — with three overlapping subscription families, live price testing on the US IAP list ($8.99 ×3, $59.99 ×4, $39.99, $29.99) and a lifetime $179.99 SKU visible only on the website's comparison page. RightRep is one app and one subscription for training and nutrition together, priced once in public, with the training half free forever.

🇧🇷

Portuguese everywhere, at Brazilian prices

The Brazil seam is a platform split: the Google Play listing is localized to Portuguese while the iOS app is "Currently available in English only" by their own admission — the BR App Store serves the US description verbatim, to 80 BR ratings at 4.83★ — and the BR IAP ladder still runs R$ 28,90–249,90 on that English listing, with PlateAI from R$ 59,90/mo. RightRep ships six locales with pt-BR everywhere — photo meal estimates, spoken cues, plans and the web app included — with no region gates on any feature.

🔓

The training half is free, forever

MyNetDiary's free tier is genuinely generous — on the nutrition side (we concede it below at full length). RightRep extends the same shape to movement: live form checks (10/day), GPS runs, race-goal training plans, history and the exercise library cost nothing, and the AI features ride the 7-day free trial every account starts with. You can train with the camera for years without ever paying us.

Where MyNetDiary wins

The other side of the comparison — because a page that only praises one column is an ad.

Twenty years of one principle

Founded December 2005, iPhone app August 2008, web app 2007, Android and iPad 2010 — and still privately held and self-funded, never sold. "Since 2005, MyNetDiary has built nutrition tracking around one principle: the data has to be right" outlived every fad this comparison family cycled through, and the tenure claim every rival reaches for, MyNetDiary actually holds. The New York Times called it "simpler, quicker, and better-looking than the competition" and Forbes Health named it "top weight loss app" (2025) — description-pinned marketing, quoted as exhibits — but twenty independent years is a fact, not a quote. This row is theirs.

The verified-database discipline

More than 2 million staff-verified foods with up to 108 nutrients per entry, "built on USDA and NCC research-grade sources, the same databases used in clinical research," a team reviewing "2,500-3,500 foods every day," and "more than 50 other apps and services" licensing the result — quality-as-moat against the 20.5M- and 56M-item crowdsourced claims elsewhere in the row, and the reason their Meal Scan can promise photos "matched against the staff-verified database." RightRep ships no food database to search at all. If verified-database nutrition is your axis, this row is theirs, conceded wholesale.

The evidence stack, misses included

Four independent peer-reviewed studies — AJPM 2013 (13 of 20 evidence-based strategies; the next apps 25%), JMIR mHealth 2015 (ranked 2nd and 4th of 28), Nutrients 2024 (tied 3rd of 18 on quality), Nutrition and Health 2026 (highest quality score of 17 apps, energy estimate within 5 calories of a 2,005 kcal reference) — plus their own JMIR 2026 — company research, employee-authored, association-only, with the limits stated — plus a Virginia Tech type-2-diabetes trial and a Kansas RE-TOOL trial using the app as a tool. The remarkable part: their research page prints the 2015 result where MyNetDiary had the second-largest energy overestimate of 23 apps and the 2024 menu-dependent flips, next to the wins — and closes with "no study crowns a 'most accurate' app." Publishing the unfavorable results is what makes the favorable ones credible. The strongest evidence posture in this family, full stop.

Free Means Free — and it's a product, not a demo

"No ads, no account required, no paywall tricks": free barcode scanning (while MyFitnessPal locks theirs behind Premium), free voice logging, 108 nutrients, charts with "no chart caps," an Apple Watch app and widgets, and no ads in any tier at all — subscription-only monetization by policy. Professional Connect — sharing your diary with a dietitian or doctor — is free too. The generosity is the marketing, and it converts exactly the user our free-forever movement half targets. We respect the shape by conceding it plainly.

The GLP-1 and diabetes verticals, actually shipped

A GLP-1 Companion with dose logging, blood-sugar tracking (free), side-effect logging "alongside meals," "protein targets and muscle protection while you lose weight" and a GLP-1-specific AI Coach for "Ozempic, Wegovy, Mounjaro, Zepbound" users; in-app blood pressure, glucose, A1C and ketones logging; a dedicated Diabetes Tracker app since 2012; a university type-2-diabetes trial running on it. It is the only product in this row that treats clinical-adjacent users as a primary audience — where the others wave at GLP-1, MyNetDiary ships. RightRep ships none of this (medication tracking stays human-gated on our side), and this row is theirs without argument.

The professional wedge and the lifetime door

Three professional doors on a consumer app: Professional Connect (free dietitian sharing), a partner directory of nutrition counselors, and the licensed database business itself — the shipped version of the health-ecosystem play the rest of the row writes roadmaps about. And the $179.99 lifetime tier — visible on their site's comparison page — is the trust artifact the subscription-averse user actually wants; Lose It! and Hevy carry the same door. We price one way, in public, and our "no lock-in" row is the free Health-app export instead — but the lifetime door itself is a real pricing truth, conceded here.

The honest summary: twenty independent years of staff-verified data with 108 nutrients per entry, a research page that publishes its own misses, a free tier that means it, GLP-1 and diabetes sides that actually shipped, professional doors and a lifetime price? That's MyNetDiary, and it is genuinely the best-measured diary in the business. A camera that estimates the plate and then measures every rep of the workout, with the training half free forever and Portuguese everywhere? That's the job RightRep does that MyNetDiary has never put a lens on.

How RightRep's meal estimate works

What actually happens between "photograph the plate" and the day's totals.

🍽️

One photo, one honest estimate

The photo (downscaled) plus any text goes to the AI, which returns a name, an estimated calorie total, a per-item breakdown, approximate protein/carbs/fat for the portion, and any drinks it identified — each one a tap to log into the hydration history. There is no database to search and no barcode to find: the plate itself is the query, in every locale we ship.

✏️

You keep the last word

The AI total is a guess about portion size, so a pencil action sits next to it — on the result card and on every saved meal — to correct the number, and the fix rewrites the row and syncs to your other devices. Day totals, charts and the weekly review all follow the corrected value, not the model's first attempt.

🎥

The same camera, gym floor

The meal photo and the form check are one stack, not two apps: the pose model that tracks 33 body landmarks per frame on the device scores every rep against readable rules — 46 bundled Position Profiles today, and Machine Scan drafts a new one from a photo of an unfamiliar machine. Their adaptive math ingests typed diaries and scale weight; our loop also knows what the training actually was — because the app watched it — and the weekly AI nutrition review is built on that.

Comparison questions

The questions people actually ask before choosing.

I want a calorie tracker — which one?

If the axis is data quality — staff-verified entries, 108 nutrients, an evidence page that prints its own misses — MyNetDiary is the old-guard benchmark, honestly, and this page says so above. RightRep is for the person whose other half is the problem: photograph the plate instead of searching it, then have the same app watch and score the workout, with an adaptive calorie goal reading both. On the macro-tracker bench between us: MyFitnessPal owns the 20.5M-food scale, Yazio ships the fasting clock free with AI logging in Portuguese, FatSecret carries the best Brazilian store score (4.87★), Lose It! is the original counter, Cronometer goes deepest on micronutrients and MacroFactor is the explained adaptive algorithm — each worth their own look if nutrition is your only axis.

How does food logging differ?

MyNetDiary logs by free barcode scan, quick search over 2 million verified foods, free voice logging, and — in Premium — Meal Scan: photograph the plate and get entries "matched against the staff-verified database"; Premium Plus adds AI voice logging and an AI Restaurant Menu Scan. RightRep's photo is the logging verb, typing the fallback: the AI returns the name, calories, per-item macros and drinks directly, in every locale we ship. We have no barcode scanner today — barcode-to-label auto-fill sits in our public research backlog, un-built — and if packaged-food scanning is your routine, that row is theirs. The honest contrast is the fence: their photo path resolves against a curated database, ours estimates and hands you the pencil.

Does MyNetDiary track workouts?

As typed entries: "exercise tracking" on the free list means logging exercise by hand — calories burned looked up and entered — and across all five store apps there is no camera, no rep counting and no GPS recording. RightRep's whole first half is that measurement: 33 body landmarks per frame on the device, a 0–100 score per completed rep, GPS run/walk recording and race-goal plans, in the same subscription as the nutrition.

What does each cost?

MyNetDiary: the free tier is real — barcode, voice logging, 108 nutrients, no ads, no account required — then Premium $8.99/mo or $59.99/yr ("about $5 per month," their words), with the live US IAP list testing $29.99 and $39.99 variants; Premium Plus $14.99/mo or $99.99/yr for the AI Coach; a $179.99 lifetime door on their site; BR points R$ 28,90 / R$ 124,90 / R$ 194,90 / R$ 249,90 on the main app with PlateAI from R$ 59,90/mo — the scatter is live price testing, so this page pins the vantage (2026-09-30) and never averages. RightRep: live form checks (10/day), GPS runs, training plans, history and the exercise library free forever; the AI features — meal estimates (10/day), the weekly review, coach chat — come with the 7-day free trial every account starts with, then Pro at $9.99/month or $99.99/year (cloud sync, ad-free, extra custom profiles). Their annual anchor is $40 below ours and conceded plainly — their dollar buys the best-measured diary in the business; ours buys training and nutrition in one loop, with the movement half free.

I'm in Brazil — which one?

The platform split, stated precisely: MyNetDiary's Google Play listing is localized to Portuguese, but the iOS app is "Currently available in English only" by their own comparison page's admission — the BR App Store serves the US description verbatim — and the footprint is 80 BR ratings at 4.83★ against 167,290 US at 4.81★ (iTunes lookup, 2026-09-30), the thinnest of the row, while the BR IAPs still run R$ 28,90+/mo on that English listing. MyFitnessPal is the incumbent here; MyNetDiary is a US-institution footnote in Brazil. The honest local framing: "o diário mais medido da América vs o treinamento que a câmera observa — em português" — if the measured English-language diary is what you want, it's theirs; if you want the camera that estimates the plate in pt-BR and then scores every rep of the treino, RightRep ships all of it in Portuguese — photo estimates, spoken cues, plans, the web app — with no region gates on any feature.

Who sees my data?

MyNetDiary monetizes subscription-only with zero ad revenue by policy — "no ads" holds in every tier, which removes the ad-tech incentive entirely — and its exit is solid if web-gated: CSV export lives on the web account (Analysis tab → Data Export), deletion via their privacy policy's support channel. RightRep runs live pose analysis on the device — live-check video is not uploaded — prices once in public, keeps ads off the camera and summary surfaces entirely (and out of the app entirely until the trial ends), and the Apple Health / Health Connect export is free for everyone. Both companies' own pages, linked below, are the full picture.
