Verdict
The clearest difference is price: Intervals at Free against HIT Log Pro's $4.99. Intervals also leads on rating (5.0 vs 4.1) and iOS requirement (12.1 vs 26.0). HIT Log Pro's advantage is ads (none vs shown) and chart position (#195 vs unranked). On update cadence, in-app purchases and device support there is nothing between them.
