Verdict

The call

The clearest difference is ads: Boxa at none against Interval Timer's shown. Boxa also leads on review sentiment (83% vs 69%) and update cadence (every 4 days vs every 9 days). Interval Timer's advantage is ratings volume (19K vs 4) and device support (4 vs 2). On price, rating, in-app purchases and monetization model there is nothing between them.
