Steady
Weight tracking that stays calm when the scale doesn't.
Context
An iOS weight tracker with two screens, no account and no backend. Your weight lives in Apple Health and the app contains no networking code at all — and since the source is open, you can check that yourself instead of taking my word for it.
Why I built it
Every weight app I tried wanted an account, a streak and a subscription for a chart, to do a thing that takes four seconds. The real problem is that weight swings two kilos a day on salt and water while actual fat loss runs about 400 grams a week, so the thing you want to know is five times smaller than the noise sitting on top of it. Steady leads with the smoothed line and keeps today's reading next to it, rather than presenting one morning as a verdict. Tuning the constant that makes that line calm without making it late took longer than building both screens.
