Loop your focus, second by second.
SecondLoop is a minimal interval timer that counts only in seconds — no minutes, ever. Set your phases (prepare → work → rest), build
presets, and let the loop drive your rhythm.
Features:
- Seconds-only display for precise control
- Auto-cycling through prepare / work / rest phases
- Save up to 10 custom presets
- Crystal-clear sound alerts via waveform synthesis
- Dark & Light mode
- Works offline with cloud sync
Perfect for study sprints, cooking, presentation practice, meditation, breathing exercises, HIIT, and more.
Simple as: how many seconds on, how many seconds off. That's it.
