What's New in IntervalFree

1.1.2

September 28, 2026

• NEW: Custom mode — build a routine from multiple blocks, each with its own action time, rest time, and rounds. Warm-up, workout, and cool-down can now run as one seamless timer. • Protected presets — your saved workouts stay exactly as you left them. Tap Edit to change anything; your edits are kept when you tap Save Preset or Start. • Simple mode is untouched — everything works just as you're used to.

Surprisingly great! It works absolutely amazing! Everyone should give it a try, okay? 😭❤️🩷❤️

I can't believe the quality of this free app - it totally exceeded my expectations. It's even better and easier to use than most paid apps out there. I'll definitely continue to support the developer - keep up the good work!!! Looking forward to more updates and more useful features! Thank you, developer!
