Cal AI made photo-first calorie tracking famous, and it deserves the credit. CountNutri works the same way — photograph the plate, get calories and macros — with a different shape: a real web app alongside Android, fixed published pricing, a longer trial, and an AI tuned for mixed plates like rice and curry. Every Cal AI claim here comes from its own site and store listings.

Both apps bet on the camera. The differences that matter day to day:
Cal AI is a phone app for iOS and Android. CountNutri runs on Android and in any browser at countnutri.com — scan from your phone, review your history on a laptop.
Cal AI’s FAQ states it "is about 80% accurate". We publish no accuracy number at all, because we believe no honest single figure exists — every result is an adjustable estimate, cross-checked against USDA data.
CountNutri’s analysis adapts to the cuisine you select and is built for plates where dishes are cooked together — rice and curry, dhal with greens, kottu, biryani.
We build CountNutri, so read us as a biased-but-honest source. Cal AI rows reflect calai.app, its FAQ and its store listings as of August 2026 — check theirs before deciding, features change fast.

Both are photo-first calorie trackers. The practical differences: CountNutri has a web app alongside Android and publishes fixed pricing ($9.99/month, $99.99/year) with a 7-day trial; Cal AI is a mobile app for iOS and Android with a 3-day trial and no public pricing page (its App Store subscription prices range from $2.99 to $29.99 without listed durations). CountNutri is also tuned for mixed South Asian plates like rice and curry.
Cal AI publishes its own figure — its FAQ says the app 'is about 80% accurate' and notes no food tracking app is perfect. We take a different position: we believe no single honest accuracy number exists for photo estimation of arbitrary meals, so we publish none. Every CountNutri result is an adjustable estimate, cross-checked against USDA FoodData Central, and you can correct any item in a tap.
Cal AI is free to download with a 3-day free trial, and its App Store listing notes that food scanning analysis results require a subscription. CountNutri offers a 7-day free trial with 1 AI scan per day, no credit card required.
Cal AI's FAQ states subscriptions are tied to the platform you purchased on — an iPhone subscription does not carry over to Android and vice versa. A CountNutri subscription belongs to your account, so it works on the web app and the Android app together.
Honest answer: Cal AI supports iPhone (CountNutri has no iOS app yet), lists an Apple Watch app, and offers barcode scanning and free-text meal descriptions alongside photos. It is hugely popular, with 4.8 stars from over 350,000 App Store ratings as of August 2026. If you are on iOS, it is the obvious pick between the two.
