Hayago

Hayago is a simple, functional, and efficient time control software for Android. It doesn't
require any permissions and it doesn't try to be more than what it is.

It comes with everything you'd expect from a go/chess clock, but nothing more.

Features:

- byo-yomi, canadian overtime, and sudden death modes
- time presets(bullet, blitz, rapid)
- time increment
- audio feedback for start/stop, low time, player's turn change.
- landscape mode
- black/grey/white aesthetic
- minimalist and lightweight
