Verdict

The call

The clearest difference is ads: BellBlock at none against HIIT Interval Timer's shown. BellBlock also leads on update cadence (every 2 days vs fortnightly). HIIT Interval Timer's advantage is iOS requirement (15.0 vs 18.0). On price, in-app purchases, monetization model and device support there is nothing between them.
