Verdict

The call

The clearest difference is ads: HIIT Timer Pro at none against Interval Timer's shown. HIIT Timer Pro also leads on review sentiment (100% vs 73%) and rating (5.0 vs 4.8). Interval Timer's advantage is ratings volume (297 vs 1) and device support (4 vs 1). On price, update cadence, in-app purchases and monetization model there is nothing between them.
