Currently, the app is only available for android. I don't have an apple device to develop for iOS, but feel free to contribute if you want iOS support. The alarm and timer features use android-only code, so that will need to be ported. Everything else should mostly work fine.

Current progress:

If you found the app useful, you can help the project by sharing it with friends and family.

The amount of time I can given to the app is bound by financial constraints. Donations will really help allow me in giving more and more time to the development of this app.
