See where you're heading
The scales wobble day to day. Log consistently and Weighly's interactive chart shows where you're really heading — drag your finger along it to scrub through your history.
Free weight tracking for iPhone
The number lies.
The trend doesn't.
Your weight wobbles every morning — water, salt, sleep, life. Weighly takes ten seconds a day and shows you where you're really heading — privately, on your device.

One heavy morning means nothing
Day-to-day readings can swing by a kilogram or more for reasons that have nothing to do with progress. That's why Weighly is built around consistency: log regularly, glance at the chart, and let the noise cancel itself out.
No streak guilt, no judgemental graphs — just an honest picture of where you're heading.
Everything you need, nothing you don't
Built for the habit, not the hype
Reach your goal
Set a target weight and watch your progress ring fill, with your all-time change always one glance away.
Progress photos
Attach up to four photos to any entry — front, back, left and right — then compare two side by side to see how far you've come.
Calories & macros
Log meals in seconds with food search and barcode scanning, and watch calories, protein, carbs and fat tick towards a daily target personalised to your goal.
Your workouts
Connected to Apple Health, Weighly shows your workouts, heart rate and energy burned — and feeds what you burn back into your calorie budget.
Share your wins
Turn any workout into a ready-made post or video for social media — your stats and heart rate on a card that looks great in light or dark.
Your units
Kilograms, pounds or stone — switch any time and your history converts instantly. Backdate entries for the days you missed.
Gentle reminders
A nudge at the time you choose — anywhere from daily to monthly — so the habit quietly sticks.
Yours to keep
Export your full history to CSV whenever you like, and share a ready-made progress chart with anyone you choose.
Speaks your language
Available in English, French, German, Spanish, Italian and Brazilian Portuguese, with light, dark and system themes.
Completely free
No subscriptions, no in-app purchases, no adverts — calories and workouts included. Weighly is free, that's it.
A quiet, native design
At home on your iPhone
Your body is nobody's business
Weighly is private by design — not as a setting, but as the way it's built.
- Your weights, goals and photos stay on your device — never uploaded to our servers
- Sign in with Apple is the only sign-in — no passwords, no email lists
- Analytics is optional and opt-in, and never includes your weight
- No tracking across other apps or websites, and we never sell your data
- Delete your account and all your data from inside the app
The details, in plain English: our Privacy Policy.
