Platforms

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.

Development

This app is built using flutter. To start developing:

  1. Follow this guide to install flutter and all required tools.
  2. Run the app by flutter run --flavor dev. For production builds, use flutter build apk --release --split-per-abi --flavor prod.
