Verdict
The clearest difference is in-app purchases: Roundwork at none against HIIT Interval Timer's 1. Roundwork also leads on ads (none vs shown) and update cadence (every 2 weeks vs every 5 months). HIIT Interval Timer's advantage is iOS requirement (15.6 vs 26.0). On price and device support there is nothing between them.
