Best Overall Free HIIT Timer App:
Seconds Interval Timer
TODAY'S BEST DEALS
If you only download one free HIIT timer in 2025, make it Seconds. Even in its free version, it’s clean, reliable, and powerful enough for most workouts. We’ve used it for Tabata, circuits, and long EMOMs, and it never misses a beat. And if you own a Apple Watch, you should definitely take a look at our Best Fitness Apps for Apple Watch (2025).
Why It Stands Out
- Free version includes customizable intervals for Tabata, EMOM, circuits
- Voice cues and color-coded screens keep you focused
- Runs smoothly in the background with your playlist or podcast
- Apple Watch support for quick wrist control
- Upgrade unlocks saving multiple custom timers, but not required for basics
What’s Great ✅
- Clear audio + visual alerts
- Works with music in background
- Apple Watch support
- Customizable workouts
What’s Not ❌
- Can’t save multiple timers
- Setup takes a bit longer at first
The bottom line
Seconds remains the gold standard HIIT timer app, even with its free version. While power users may eventually upgrade, the free features are more than enough for most people who just want a reliable, customizable interval timer.

Best 100% Free HIIT Timer App:
O’Coach
TODAY'S BEST DEALS
