Verdict

The call

The clearest difference is monetization model: Interval Timer HIIT Workout at free with in-app purchases against Interval Timer's subscription. Interval Timer HIIT Workout also leads on update cadence (weekly vs every 4 weeks) and device support (3 vs 1). Interval Timer's advantage is ads (none vs shown) and ratings volume (3.5K vs 332). On price, rating, review sentiment and in-app purchases there is nothing between them.
