It’s a weight tracking app. It keeps all the data locally and keeps bugging you to back the local data up somewhere. It’s just so subtly good - it has this “stats” screen which is for some reason addictive to keep checking - it shows your current BMI, how many days you have left till your goal weight. It graphs your weight. The log-weight-by-dragging-the-scale thing is also great. There’s 3 total views in the app - that’s it.

I don’t know it’s just sensorially respectful?
