Frequently Asked Questions
What is Interval Timer?▼
Interval Timer is a flexible, customisable timer app for HIIT workouts, Tabata, circuit training, stretching routines, and any activity that requires timed intervals. It features audio cues, vibration alerts, and a clear full-screen countdown display.
Can I create custom interval programmes?▼
Yes. You can define any number of work and rest intervals, set custom durations, add unlimited rounds, and save your programmes for future use. Custom colour coding helps distinguish different interval types at a glance.
Does Interval Timer work with earphones?▼
Yes. Audio cues (beeps, voice announcements) play through any connected audio device including AirPods, Bluetooth headphones, or wired earphones, so you can hear interval changes without looking at the screen.
Can I use Interval Timer while other apps are running?▼
Yes. Interval Timer runs in the background and plays audio cues even when your phone is locked or you are using another app, so you can follow a workout while watching a tutorial video simultaneously.
Is Interval Timer free?▼
Interval Timer is free with basic presets. A Pro upgrade unlocks unlimited custom programmes, Apple Watch integration, and advanced statistics.
