The clearest difference is rating: CompTrain at 4.8 against Thundr App's 3.8. CompTrain also leads on update cadence (fortnightly vs every 27 months) and ratings volume (46 vs 12).

CompTrain holds the better App Store score, 4.8 against 3.8. Both are backed by a comparable volume of ratings — 46 and 12 respectively. Written reviews complicate that: 53% of CompTrain's written reviews are positive against 64% of Thundr App's, so the app with the better star average is not the one people write more warmly about.
