About

Interval Working

Features
Read full description

Interval Working helps you train with more intensity, fewer distractions, and better control. Create workouts for HIIT, Tabata, cardio, circuits, boxing, or fully custom sessions. Set up warm up, work blocks, rest periods, and cool down in one routine. During training, voice cues help you keep going without constantly checking the screen. That makes it easier to stay focused and maintain the right effort. If you use a Bluetooth heart rate sensor, you can also train with heart rate guidance to better control your intensity in every interval. Main features: • Build interval workouts in seconds • Configure work, rest, warm up, and cool down • Follow sessions with voice cues • Works with Bluetooth heart rate sensors • Great for HIIT, Tabata, cardio, circuits, and boxing • Useful for quick workouts or longer sessions Interval Working is built for people who want an interval timer that does more than a basic stopwatch and helps them train in a clearer, faster, and more effective way.

Verdict

The call

The clearest difference is in-app purchases: Interval Working at none against Red Diary's 1. Interval Working also leads on iOS requirement (15.6 vs 17.1). Red Diary's advantage is ads (none vs shown) and update cadence (every 6 weeks vs every 6 months). On price and device support there is nothing between them.
