Know My Meals vs Cal AI

Cal AI is built around a photo of your plate. Know My Meals takes a photo too, or your voice, or a typed sentence, and shows you every ingredient behind the number so you can fix the one that's off. Its coach, ChatGPT and Claude can all answer from your own log.

$11.99 a month or $71.99 a year, every feature included. iPhone only, no free tier or trial.

We make Know My Meals. Cal AI facts below come from its own pages, linked under Sources.

Why Know My Meals

Photo, voice or text: whichever fits the meal

Plenty of meals are hard to photograph: a smoothie, a sandwich with the fillings hidden, the chips you finished in the car. Say it in one sentence, like "a turkey club and a small bag of Lay's", or type it. When a photo is easier, take one and add a note such as "cooked in butter". The meal is saved as soon as you send it, and the estimate fills in right after.

You see every ingredient, and fix the one that's off

A burrito bowl comes back as separate lines for the rice, chicken, beans, salsa, cheese and guac, each with grams and calories. Cooking oil, butter and dressings get their own lines. Went light on rice? Set it to ½×. Extra guac? Make it 2×. No cheese? Remove it. Forgot the chips? Tap + Add. The other lines stay put and the totals update.

A coach that has read your log

Ask "How much protein have I had today?" or "What should I eat tonight to hit protein?" and the coach answers from the meals you logged and your targets.

ChatGPT and Claude, on your own log

Connect Know My Meals to Claude or ChatGPT and ask "Where do most of my calories come from?" there. They can read your log but can't change it. See Connect your AI for setup and which ChatGPT plans allow it.

Clean and private

Today shows your calories, macros and meals on one screen, and Quick log suggests what you usually eat at this time of day. Cal AI's App Store privacy label lists identifiers and usage data under "Data Used to Track You"1. The Know My Meals label has no tracking section6. We keep the text of what you logged, not your voice recordings or photos.

Built by a founder who listens. Know My Meals is made by its founder, Samarth Mamadapur, who reads the feedback that comes in and uses it to decide what to fix and build next. Tell us what's off or missing on the help page, or under You > Help and feedback in the app.
