COMPARE

RightRep vs Cronometer.
An honest look.

Cronometer (Cronometer Software Inc., Revelstoke, British Columbia — born in 2005 as developer Aaron Davidson's CRON-diet side project, incorporated 2011, bootstrapped ever since) is the accuracy-first nutrition tracker: a curated database of more than 1.1 million verified foods drawn from "verified, lab-analyzed sources like the Nutrition Coordinating Center and the USDA" — the deliberate inversion of the crowd-count databases, argued in their own "Small is Better" blog post — with the barcode scanner, the full macro and micronutrient grid, custom targets and a full CSV export all free ("never hide essential nutrition information behind a paywall"), while Gold at $10.99/month or $59.99/year gates the speed surfaces: the AI Photo Log, Voice Log, Crono Coach, the fasting timer, recipe import — and the user's own history beyond a 7-day chart window. Underneath sits Cronometer Pro, a $39.99/month HIPAA/GDPR/CCPA dietitian platform "trusted by hospitals and universities across the globe" — the clinical moat. This page concedes all of it. What Cronometer never does is observe a movement: exercise is a manual diary plus device imports from Fitbit, Garmin, Oura, WHOOP and Dexcom — no camera, no rep counting, no GPS recording, no coaching plans. RightRep is the other half of fitness: 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 Brazil Cronometer is the nutrition-nerd niche — 4.78★ across 185 ratings, an EN-only iOS localization list and a US-centric database the category's international users flag — while RightRep ships every feature in Portuguese. Every Cronometer claim on this page is cited to Cronometer's own materials or named sources, and the places where Cronometer 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.

🔬

Cronometer

The verified-database nutrition diary — a calorie counter and nutrition tracker "designed for accuracy" (US App Store listing), built on "a curated database of more than 1.1 million verified foods, including analyzed entries for unmatched accuracy," with data "not crowdsourced but drawn from verified, lab-analyzed sources like the Nutrition Coordinating Center and the USDA" (About page). The free tier keeps the science: the barcode scanner is free, full macro and micronutrient data is free ("Track up to 95 different nutrients and compounds" — homepage figure), custom macro and micronutrient targets are free, device sync is free, and "Export your data as a .csv file" covering diary, exercises, biometrics and notes is free. Gold ($10.99/month · $59.99/year) sells the speed: the AI Photo Log, Voice Log, Crono Coach, Fasting Timer, Macro Scheduler, recipe import by URL, ad removal — and "unlimited historical data" past the free tier's 7-day reports window. Underneath, Cronometer Pro at $39.99/month (HIPAA/GDPR/CCPA, 10 client seats, clients get Gold free) sells the same verified data to dietitians. 4.77★ across 98,762 US ratings on iOS, 5M+ installs · 4.5★ on Play, Apple Watch and Wear OS apps, a full web app — and an EN-only iOS localization list with a US-centric database at its core.

📱

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.

Where RightRep wins

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

🏋️

The movement half they never observe

In Cronometer a workout is a row to type and a device to import — Fitbit, Garmin, Oura, WHOOP, Dexcom credits land in the exercise diary, but no camera has ever checked a rep and there is no GPS surface at all. 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. One subscription covers the plate and the platform.

🇧🇷

The AI that ships in every locale we serve

Cronometer's database core is NCCDB and USDA — US datasets — and the category's international reviewers flag exactly that: local products thin out on non-US supermarket shelves, and the iOS localization list is EN-only while the BR store serves 185 ratings. RightRep's photo meal estimate ships in every locale we offer — Portuguese included — riding the same 7-day free trial as everything else, with the free and paid rows labeled plainly on this very page.

📅

History is never the upsell

Cronometer's free tier keeps "reports and charts within a 7-day window" — and sells "unlimited historical data" as the Gold unlock. A user's own log is the one thing that should never be inventory. RightRep's history is free on every plan: sessions, meals, charts and the weekly review stay yours whether you pay or not.

🔓

On-device analysis, no ads against the diary

Cronometer's free tier "Contains ads" (Play listing) — inside the most personal log a user keeps — and its AI photo and voice logging sit behind Gold. RightRep runs live pose analysis on the device (live-check video is not uploaded), keeps ads away from the camera and summary moments entirely, ships both watch companions — Apple Watch and Wear OS — un-gated, and the AI meal estimate rides the 7-day free trial every account starts with.

Where Cronometer wins

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

The curated, lab-analyzed database

"A curated database of more than 1.1 million verified foods" drawn from "verified, lab-analyzed sources like the Nutrition Coordinating Center and the USDA" — the accuracy argument their own "Small is Better" post makes against every crowd-count rival, and the reason dietitians and universities trust the data. RightRep ships no food database to search and no barcode at all: the photo estimate is our whole logging surface. If verification-by-curation is your axis, this row is theirs, outright.

The micronutrient grid, free

"Track up to 95 different nutrients and compounds" (homepage figure) against personalized targets at $0 — vitamins and minerals with "identify nutrient gaps" built in, the most scientifically generous free tier in this comparison family. RightRep does macros — protein-first targets, adaptive calories — and the micronutrient grid is a public backlog rung, not shipped. The nutrition-nerd row belongs to Cronometer.

The deepest device ingestion in the family

"Connect Fitbit, Garmin, Oura, Whoop, and more" (iOS listing) plus "Sync with Health Connect and Wear OS" (Play) plus Dexcom — a CGM line no other app in this family names on its listing. They ingest everything — and ship both watch apps, Apple Watch and Wear OS, one of only two products in the family that do. RightRep reads Apple Health and Health Connect and ships both watch companions, but the quantified-self long tail is theirs, uncontested.

The clinical arm — Cronometer Pro

A $39.99/month HIPAA/GDPR/CCPA platform for dietitians with real-time client dashboards, 10 seats at the base price, "a 24-hour dietary recall in under 10 minutes", clients getting Gold free — "trusted by hospitals and universities across the globe." RightRep ships nothing professional-facing; the compliant clinical revenue line is theirs alone in this family.

Twenty years of quiet, bootstrapped restraint

A 2005 side project that founder Aaron Davidson incorporated in 2011 and grew from Revelstoke, BC with no funding rounds and no owner churn — "over 10 million people around the world use Cronometer" (About page). Longevity plus restraint is brand equity in health data. RightRep is a young app at field-test stage; we never claim tenure, and this row is theirs.

The free exit, file and all

"Export your data as a .csv file" — diary entries, exercises, biometrics and notes, free accounts included, documented in their own help center. The best data-freedom posture in this comparison family. RightRep's Apple Health / Health Connect export is free on every plan too, but the full-file, everything-in-one-CSV door is the deeper exit, and the honesty row is theirs.

The honest summary: a bootstrapped twenty-year-old tracker with a lab-analyzed 1.1-million-food database, a free micronutrient grid, the deepest device ingestion in the family and a HIPAA dietitian platform on top? That's Cronometer, and it is genuinely the best at what it does. A camera that estimates the plate and then measures every rep of the workout, with the weekly review that reads both? That's the job RightRep does that Cronometer deliberately doesn't try.

How RightRep's meal estimate works

What actually happens between "photograph the plate" and the day's totals — and how we answer the accuracy objection.

🍽️

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 — that's the accuracy answer

Cronometer's answer to accuracy is a curated database; ours is the loop around the estimate. 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. Nutrition that knows what the workout actually was — because the app watched it — is what the weekly AI nutrition review is built on.

Comparison questions

The questions people actually ask before choosing.

I want to track my nutrition — which one?

If the verified-database loop is what you want — search a curated lab-analyzed database, scan the barcode, watch the micronutrient grid fill against targets — Cronometer, honestly: it has run that loop since 2005 and the data-quality story is the row's best. 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. 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★), and Lose It! is the original counter — each worth their own look if nutrition is your only axis.

Does RightRep scan barcodes?

No — and this page won't dress that up. RightRep ships no barcode scanner today; the photo is our logging verb (typing is the fallback), and barcode-to-label auto-fill sits in our public research backlog, un-built. Cronometer's scanner is free and runs against the verified database behind it — genuinely theirs, conceded straight. If scanning is your routine, that row is theirs today.

Does Cronometer track workouts?

As accounting, not training: exercise lives in a manual diary ("Log foods, exercise, biometrics and notes") plus imports — "Import workouts, activity, and energy expenditure" from Fitbit, Garmin, Oura, WHOOP and Dexcom. Nothing in the app observes movement — no camera, no rep counting, no form check, no GPS surface. 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.

What does each cost?

Cronometer: free with ads — the full diary, the nutrient grid, the barcode scanner, custom targets, device sync, the CSV export and reports within a 7-day window; Gold at $10.99/month or $59.99/year ("Save 54%" annual framing; older reviews still cite $8.99/$49.99 — a 2026 hike, pinned here per the gold page live read, 2026-09-30) unlocks the AI Photo Log, Voice Log, Crono Coach, the Fasting Timer, recipe import and full history. The BR App Store surfaces Gold Mensal at R$ 69,90 and Gold Anual at R$ 319,90 (with scatter points R$ 319,00 and R$ 399,90 on the same listing — live price testing, quoted as-is). Cronometer Pro runs $39.99/month with 10 client seats. 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).

I'm in Brazil — which one?

Cronometer is the nutrition-nerd niche in Brazil: 185 BR ratings at 4.78★ (iTunes lookup, 2026-09-30) — the smallest BR footprint of this comparison family — with the store description served in pt-BR but the iOS localization list EN-only, and a NCCDB/USDA database core that international reviewers flag for thin local-product coverage. The honest local fight is "banco americano verificado vs treino observado + logging que entende o prato brasileiro": if verified-database precision 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?

Cronometer's free tier "Contains ads" (Play listing) with Gold sold as ad-free, data encrypted in transit and at rest, and the free CSV exit documented in their help center — a genuinely open posture with an ad-funded free tier. 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, and the Apple Health / Health Connect export is free for everyone. Both companies' store listings and Cronometer's own pages, linked below, are the full picture.

RightRep vs Lose It!

The tail-3 sibling: the App Store's original calorie counter with its 56+ million-item database and the Say It. Snap It. Scan It. triad behind Premium — vs the camera that estimates the plate and then scores the rep, cited the same way. Cronometer is the accuracy objection, Lose It! the establishment one; the nutrition pages read well together.
