Recently I wanted an app that would let me create a widget on one of my home screens to count down the days until a major life event. There are a lot of apps on Android to do this, but since this is a fairly niche featureset, most of them looked like garbage.
Ultimately I ended up settling on Bruno Schalch’s Time Until | Beautiful Countdowns app.
The app is free, but the home screen widget feature requires paying $2.99 for the premium version.
