Cyca サイクルタイマー

An interval timer for people who move — without stopping your music.

Strength training, running, sauna, stretching, focused work: Cyca layers "work and rest" intervals on top of your own music. It only ducks the volume for the moment an announcement or beep plays, then restores it instantly.

■ Highlights ・Doesn't stop your music: runs over other apps' playback ・Exercise mode: speaks each exercise name during rest ・Quick timer: 1/2/3/5/10 min, one tap, no setup ・Built-in presets: Tabata / HIIT / Sauna / Stretch / Pomodoro ・Custom presets: work/rest seconds, repeats, countdown sounds, pre-start countdown ・History calendar: review which days you trained, with memos ・Works with the screen off: the timer stays accurate in the background
