Frequently asked questions
Can I make any timer with this page?
This page gives you a flexible starter routine for custom work, rest, study, workout, or habit blocks.
Will custom presets be saved?
Completed sessions are saved locally today. Cloud-saved presets and cross-device sync are planned paid features.
Is this better than a phone alarm?
For repeatable routines, yes: it keeps work and break stages together and records completed sessions locally.
When should I use the custom timer instead of a preset?
Use the custom timer when your routine has a specific length, pacing, or purpose that does not fit Pomodoro, Tabata, interval, workout, focus, or stretch presets.
