You’re 3 lbs into a great arc. Keep the morning weigh-in — rest days still count.
— The proof
A line
that tells the truth.
Daily weight is noisy. One bad sleep, one salty dinner — the number jumps. The 7-day moving average cuts through it, so you see the real direction your body is heading.

The chart doesn’t lie. I stopped obsessing over daily bumps and finally saw the trend — down 11 lbs in three months.

It’s the first fitness app that doesn’t feel like it’s yelling at me. Quiet, honest, beautifully made.

I log my weight in five seconds before coffee. The streak keeps me honest. Aria’s notes are weirdly on point.
