How it works

Snap. Map. Get coached.

No forms, no spreadsheets. Your watch already did the tracking — fit101 does the thinking.

1

Snap your screenshots

Up to 20 at once — workouts, heart-rate zones, Activity, steps, sleep, weight. Any days, any order.

2

It maps everything

Each workout lands on the right day and type. Screens of the same session are merged, duplicates skipped, zones and pace read.

3

Your coach adapts

A plan built around your goals, insights after every session, a weekly review — and reminders only for what's actually missing.

Built around you

Pick every goal that's yours.

Real goals are combined. fit101 balances calories, sessions and what it asks you for — try it.

Features

Everything a good coach would notice.

Food without the spreadsheet

Write "two eggs and avocado toast" — or snap a photo. You get calories and macros per item, daily totals against your targets, and an energy-balance check that explains exactly why the scale isn't moving.

A coach you can talk to

Ask anything about your training. It looks up your full history, logs meals and weigh-ins, and updates your goals — every change with an undo.

Smarter on court

Tracks how much of your tennis or padel is spent in zones 4–5, so you can finally stop running out of breath in the third set.

Trends that explain themselves

Weight, pace, resting HR, HRV, VO₂ max, protein, measurements — each chart with a plain-English summary and a coach analysis on demand.

Measurements, not just the scale

Building muscle? Track waist, chest, arms, thighs and body fat with weekly reminders and targets.

Nudges that know when to stop

Only for what's actually missing: the morning weigh-in, a workout you didn't log, tonight's meals, measurement day. Quiet hours are respected — and after the third reminder, it leaves you alone.

Coach chat

Just ask.

Write the way you talk — in English or your own language. The coach answers in kind, and does the work.

Privacy

Your data stays yours.

Photos never stored

Screenshots and meal photos are read once, then discarded. Only the numbers are saved.

Google sign-in only

No passwords to leak. Access is invite-only during the beta.

Sandboxed coach

When the coach crunches numbers, it works on a private copy of your rows — never anyone else's.

Not medical advice

fit101 is a training tool. Sharp or worsening pain? It'll tell you to see a professional.

FAQ

Questions, answered.

Do I need an Apple Watch?

It works best with one — screenshots from the Fitness, Activity, Health and Sleep apps are read automatically. You can also add workouts, meals and check-ins by hand.

Which screenshots can I upload?

Workout summaries, heart-rate zones, splits, workout lists, Activity summaries, steps, sleep, resting heart rate, HRV, VO₂ max, weight and body fat. Mix any days in one upload.

Can I write in my own language?

Yes. The app is in English, but you can write meals, notes and chat messages in your own language. The coach replies in kind.

Are my photos stored anywhere?

No. Images are held in memory just long enough to read them, then dropped. Only the extracted numbers are saved to your account.

Does it work on my phone like an app?

Yes — open it in Safari, tap Share → Add to Home Screen, and turn on notifications in Settings for reminders.

What does it cost?

It's free while in private beta.

Train smarter, starting with what you already did.

Set your goals in two minutes. Your first plan is waiting.
