Train hard. Eat better. Actually progress.
Your workout log and nutrition tracking in the same app — plus an AI coach that actually reads both before it opens its mouth.
Closed beta via TestFlight. The workout log and nutrition tracking are free; the AI coach, limited on the free plan, unlocks without limits with the subscription.
Two apps that don't talk to each other.
A workout log on one side, a nutrition app on the other. Two subscriptions, two histories — and neither one knows what the other is doing.
Separately
- Your log has no idea what you eat
- Your nutrition app has no idea how hard you trained
- Two subscriptions to pay, two accounts to manage
- A generic coach that knows neither
Inside SmartFit
- One history: workouts, macros, measurements, sleep
- Your next load accounts for how you actually felt
- One subscription, one app
- A coach that cites your own numbers
Three products, one app.
Training
A complete workout log, a rest timer that survives a locked screen, and an engine that decides your next load — and tells you why.
- Sets, supersets, drop sets
- PRs detected automatically
- Import from Hevy, Strong, FitNotes
Nutrition
All 3,178 foods from the French Ciqual database, barcode scanning, and a plate photo broken down into its ingredients.
- French Ciqual database
- AI meal photo scan
- Fridge → recipes
AI Coach
It reads your profile, your latest workouts, and today's hydration before it answers. And it commits, instead of hedging.
- Answers with your own data
- Bring your own Claude or ChatGPT key
- Generates a workout you can actually do
A suggestion you can audit.
Most logs just record. SmartFit decides your next load — and shows the reason under the exercise, so you can disagree with it.
+2.5 kg — the last two sets finished with 3 reps in reserve.
Load held — first tracked session on this exercise.
Deload — 3 sessions in a row below the rep target.
Four policies to choose from: double progression, linear, Greyskull LP, bodyweight. Nothing is hardcoded — fix one set and the prescription recalculates instantly.
No made-up numbers, ever.
No fabricated data
A screen with no data shows "no data," not a demo curve. If the API goes down, the app says so instead of showing zero.
Your AI key isn't stored
If you plug in your own Claude or ChatGPT key, it stays in the phone's keychain, gets used for one call, and is never saved or logged.
Real deletion
Deleting your account erases the rows, immediately. No silent trash bin, no "we keep it for 30 days."
Join the beta while it's still small.
On iPhone, via TestFlight. The log, nutrition tracking, and connected devices are free; the AI coach unlocks without limits with the subscription. Your feedback still carries real weight at this stage.
