Verdict

The call

The clearest difference is rating: Interval Timer at 4.9 against Round's 4.0. Interval Timer also leads on ratings volume (250 vs 1) and iOS requirement (13.0 vs 17.2). Round's advantage is in-app purchases (none vs 1) and ads (none vs shown). On price and device support there is nothing between them.
