Instead of inventing yet another clever, pretty, tedious method of inputing time, *Micro Timer* uses the tried-and-true 10-key pad commonly found on microwave ovens. 4 | 5 | The idea was born when I realized I tended to use the kitchen microwave timer because the stock Android timer was such a pain to use. Not to mention it always seemed to change/break for no aparent reason between Android versions. I thought to myself, "Wouldn't it be nice if I could have my microwave timer with me wherever I went without having to drag around a microwave?" 6 | 7 | [Get it on F-Droid](https://f-droid.org/packages/dubrowgn.microtimer/) 10 | 11 | Or download the latest APK from the [Releases Section](https://github.com/dubrowgn/micro-timer/releases/latest). 12 | 13 |
