Reads

Weigh-ins, the trend, water, steps, fasting and streaks - the whole picture, not a single day.

Explains

Why the scale jumps, whether you're on pace for your goal date, and what stands out this week.

Stays private

The coach runs entirely on your device. Your data and your messages never leave your phone.

The AI coach requires Apple Intelligence and is available only on supported devices, in supported languages and regions. Where your language isn't supported yet, the coach can answer in another supported language. Everything else in Weighly works on any device.

Progress photos

See the change the scale can't show.

Add photos with any weigh-in, then compare two days with a before and after slider or side by side - front, side and back.

Forecast

Know the date you'll hit your goal.

A forecast built from your real trend, with a range for slower and faster weeks - because real life isn't linear.
