Show it your food
Photo, voice (17+ languages), text, barcode — or just chat.
How it works
Logging, minus the logging.
Five ways in. One tap out.
2
The AI does the math
Calories, protein, carbs, fat and fiber — with its work shown.
3
One tap and it's remembered
One tap to log. Lento.fit remembers everything, day by day.
Features
Everything you need. None of the busywork.
A coach that actually remembers you.
Ask “what should I eat tonight?” and it advises. Say “I had 2 eggs” and it logs. Unlike a chatbot, it answers from what you actually ate — your whole history, not a blank slate.
A chatbot forgets you tomorrow. Lento.fit doesn't.
Knows your body.
Lento.fit computes your metabolic rate and real daily energy need, and the coach factors your actual weight and metabolism into its advice.
Goals that fit you.
Personalized calorie + macro targets from your body and activity (Mifflin-St Jeor) — pick lose 0.2 to 1 kg a week, maintain, gain, or lean-muscle. Sensible defaults, yours to override, with a target-weight ETA.
Fasting, if you want it.
A live eating-window timer with metabolic stages — fed, fat-burning, ketosis, autophagy — and protocols from 16:8 to OMAD. Flexible, never dogmatic.
Reads your steps & sleep.
Connects to Apple Health / Health Connect (read-only, private) so advice factors in how active and rested you really were.
A food library that cleans itself.
A community database that grows and AI-validates itself, plus one-tap re-logs, weight trends and streaks.
A weekly review in plain English.
It correlates your meals, fasting and weight, then tells you the one thing to tweak — no charts to decode.
More than calories.
Protein, carbs, fat, fiber and micronutrients on every estimate.
Calorie tracking for people who hate calorie tracking.
The old way
- Search a database of 40 “chicken breast” entries
- Guess the grams
- Give up by Thursday
- An app that treats you like a spreadsheet
Lento.fit
- Point your camera
- It estimates
- It remembers
- It nudges you like a friend, not a food cop
Founding testers · free during beta
Join the closed beta.
A small group of founding testers is shaping Lento.fit before launch. It's free, it already runs in your browser, and when you tell us what to fix, we build it.
First in line — you're using Lento.fit before the App Store even sees it.
Shape the app — with a team this small, your feedback actually ships.
A direct line to the makers — no support black hole; you talk to the people building it.
Free during beta + founding-tester recognition — free while we're in beta, and founding testers keep a spot in the credits.
Free during the beta — and you can try the whole app in your browser right now, no invite needed.
Straight answers
Questions, answered honestly.
Is it free?
Yes — free for the whole beta. We'll build paid plans later, but testers help us shape what's worth paying for first.
iPhone or Android — and what's TestFlight?
Both are supported. TestFlight is Apple's official beta app; for iPhone we send you a TestFlight invite, for Android we send the test build. We onboard a handful of testers a week, so there may be a short wait — earlier signups go first.
How accurate are the estimates?
Good enough to be genuinely useful, and honest about it — the AI shows how it got each number so you can nudge a portion in a tap. Save a food once or scan its barcode and Lento.fit reuses it exactly. Consistency beats false precision.
Do I have to fast or follow a diet?
Nope. Fasting and macro targets are there if you want them, off if you don't. Lento.fit is flexible, never dogmatic.
What about my data?
Health data (steps, sleep) is read-only and private. We don't sell your data, full stop.
What do I actually get as a founding tester?
Early access, a free beta, and a real say in the app — plus a direct line to the makers. No hard promises we can't keep; just the truth that early testers shape what Lento.fit becomes.
Start the tracker you'll actually keep.
Snap, say it, or chat — Lento.fit does the rest, and remembers.
