Verdict

The call

The clearest difference is ads: Timefully at none against Interval Timer's shown. Timefully also leads on rating (4.8 vs 4.5) and review sentiment (85% vs 69%). Interval Timer's advantage is ratings volume (19K vs 1.1K) and iOS requirement (13.0 vs 18.0). On price, update cadence, in-app purchases and monetization model there is nothing between them.
