Verdict

The call

The clearest difference is ads: HIIT Timer Counter at none against Interval Timer's shown. HIIT Timer Counter also leads on update cadence (fortnightly vs every 2 months). Interval Timer's advantage is device support (4 vs 1) and iOS requirement (13.0 vs 26.1). On price and in-app purchases there is nothing between them.
