Private 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.

The Weighly home screen: a seven-day weight chart, last weight, calorie and workout totals and a goal progress bar

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.

A streak that forgives rest days, no judgemental graphs, and an honest picture of where you're heading.

Everything you need, nothing you don't

Built for the habit, not the hype

See where you're heading

The scales wobble day to day. Weighly leads with your trend weight, the smoothed line underneath the noise, and every raw weigh-in is still there beneath it. Drag your finger along the chart to scrub through your history.

Reach your goal

Set a target weight and see a projected date that updates every time you log, 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.

A weekly check-in

On a day you choose, Weighly reviews the week's trend with you and adjusts your daily calorie target to match what your weight is actually doing. Skip it whenever you like. Skipping costs you nothing.

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 never includes your weight, and you can switch it off in Settings
  • 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.
