Verdict

The call

The clearest difference is ads: HIIT Timer Pro at none against Interval Timer's shown. HIIT Timer Pro also leads on update cadence (every 9 days vs every 2 months). Interval Timer's advantage is ratings volume (246 vs 1) and device support (4 vs 1). On price, rating, in-app purchases and monetization model there is nothing between them.
