Timers is an Android app I put together in late 2016 and early 2017. It has been updated for newer versions of Android (i.e. Oreo/8.x and Pie/9.0) and should still work with any Android version above 4.3.
The app is for creating multiple countdown timers with names and ring tones. You can add or remove time from timers you've made, pause them, change their ring tones, rename them or recreate timers you've created before.
You could use this app to keep track of multiple cooking times, time your workout or run, or to simply remind you about things you need to do in a few minutes or hours.
Please see the store link for screenshots.
I was planning to open source this app, but I'm really just not happy enough with the source code. If you use this app and really want to examine its source code, then please contact me and I will consider it.
