Verdict

The call

The clearest difference is review sentiment: The Gains Lab at 100% against CompTrain's 51%. CompTrain's advantage is rating (4.6 vs 4.0) and update cadence (fortnightly vs every 2 months). On price, ads, in-app purchases and monetization model there is nothing between them.

Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS

CostPrice · In-app purchases · Ads · Monetization

Both are free to download. CompTrain sells 6 in-app purchases, starting at $19.99 per month and The Gains Lab sells 11 in-app purchases, starting at $24.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

CompTrain holds the better App Store score, 4.6 against 4.0. That said, the two scores are not equally well evidenced: CompTrain has 49 ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 51% of CompTrain's written reviews are positive against 100% of The Gains Lab'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, The Gains Lab every 2 months. The most recent releases landed on October 25, 2026 and October 24, 2026 respectively.
