Verdict

The call

The clearest difference is ads: Interval Timer at none against TimeFit's shown. Interval Timer also leads on rating (5.0 vs 4.7). TimeFit's advantage is ratings volume (321 vs 2) and update cadence (fortnightly vs monthly). On price, in-app purchases, monetization model and device support there is nothing between them.
