ReceptionRating · Positive reviews · Number of ratings

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.

UpkeepUpdate frequency

CompTrain ships an update fortnightly, Thundr App every 27 months. The most recent releases landed on September 23, 2026 and September 14, 2026 respectively.
