Thank you for supporting me in the development of stagetimer.io. I just released version 1.6
Compared to v1.0 the app now has a separate controller & viewer links, presets for timers and messages, and a database. Until now, stagetimer.io was just a simple prototype. But now it is ready for more serious development. This means I can focus on new features and a monetized version. But no worries, all current features will stay free.
