Verdict

The call

The clearest difference is ads: HIIT Timer Pro at none against Round Timer's shown. HIIT Timer Pro also leads on rating (5.0 vs 4.8) and update cadence (every 9 days vs every 3 weeks). Round Timer's advantage is ratings volume (296 vs 1) and device support (4 vs 1). On price, in-app purchases and monetization model there is nothing between them.
