✔Congratulations! You just found a highly customizable countdown timer! ?

Only one timer is not always enough. Multiple or a series of timers are needed. To be precise, several timers with different lengths and loops.

This is Cycle Timer’s mission! It can automatically time, count and remind after started. It's best for work, cook, exercise, game, experiment and many other situations.

Features:
1. Customizable timer: A series of timers which can automatically time, remind and cycle.
2. Background mode: Reminds you even if the screen is off.
3. Multiple remind modes: You can decide if the reminding sound is played as an alarm or multi-media(just in headphones), even don't remind you at all.
4. Concise interface: Concise and easy to use (of course it’s Material Design).
