The 5 Best Interval Timer Apps

High-intensity interval training (HIIT) is the fastest way to build an athletic body and improve endurance. But trying to track time manually — by looking at a clock or guessing when an interval ends — always throws you off your rhythm. You need an “autopilot” that handles the timing so you can focus entirely on maximum intensity.

We selected 6 of the best free apps that cover every need: from simple timers to full-featured workout systems.

SECONDS INTERVAL TIMER

If you only download one app, make it Seconds. Even in the free version, this timer remains the benchmark for reliability. We tested it in every scenario: from classic Tabata to exhausting EMOM sessions — the app works flawlessly.

• Flexible setup: the free version includes ready-made templates for Tabata, EMOM, and circuit training.
• Process-focused: voice prompts and high-contrast screen colors help you stay on pace even during maximum effort.
• Background operation: the timer works perfectly alongside your music playlist or podcast.
• Apple Watch support: you can fully control workouts directly from your wrist without taking your phone out of your pocket.

The free functionality is enough for 90% of users. The paid version is mainly useful for professional coaches who need to store dozens of unique templates.

TABATA TIMER: INTERVAL TIMER

If your training is focused purely on Tabata or interval workouts, there is no reason to waste time on overloaded interfaces. This app keeps the rhythm simple and effective.

• Narrow specialization: the app is built specifically for HIIT and Tabata, so every feature is easy to access.
• Full customization: you can flexibly adjust work and rest periods for your own training style.
• Audio guidance: clear voice commands help maintain intensity throughout the workout.
• Background mode: music and audiobooks continue playing without interruptions.
• Session saving: you can create and reuse your workouts even in the free version.

This is a perfect choice for anyone looking for a practical tool without visual clutter — one that simply works reliably.
