On in-app purchases, monetization model and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

HIIT Interval Timer holds the better App Store score, 4.2 against 3.5.

Written reviews complicate that: 53% of HIIT Interval Timer's written reviews are positive against 100% of Best Interval Timer's, so the app with the better star average is not the one people write more warmly about.
