Most interval timers force everything into the same work/rest pair. ChainFlow lets every step in your sequence have its own name and duration — build it once, then run it hands-free from first step to last.

A fixed 20/10 or 45/15 timer only works until your routine doesn't fit that shape. ChainFlow is built the other way around: you define a sequence — any number of steps, any order, any durations — and it runs exactly that, automatically.
| Step | Duration |
|---|---|
| Warm Up | 1:00 |
| Jumping Jacks | 0:45 |
| Rest | 0:15 |
| Squats | 0:45 |
| Rest | 0:15 |
| Plank | 0:30 |
| Cooldown | 2:00 |
Start from scratch, or pick a bundled template close to what you need.
Give each step its own name and length, then arrange them however you like.
Press play and it runs itself — audio cues mark every transition automatically.
Most interval timers repeat one fixed work/rest pair. ChainFlow lets every step have its own name and duration, so a warm-up, six different exercises, and a cooldown can all live in one routine.
As many as you need. Add, reorder, duplicate, and delete steps freely, and adjust any single step's timing without affecting the others.
