Verdict

The call

The clearest difference is in-app purchases: 531 Trainer at none against GZCL Method Workout Logger's 2. 531 Trainer also leads on review sentiment (82% vs 63%) and iOS requirement (7.1 vs 13.0). GZCL Method Workout Logger's advantage is rating (4.7 vs 4.3) and ratings volume (230 vs 10). On price, update cadence, ads and device support there is nothing between them.

ReceptionRating · Positive reviews · Number of ratings

GZCL Method Workout Logger holds the better App Store score, 4.7 against 4.3. That said, the two scores are not equally well evidenced: GZCL Method Workout Logger has 230 ratings behind it against 10, so its average is the more settled of the two. Written reviews complicate that: 82% of 531 Trainer's written reviews are positive against 63% of GZCL Method Workout Logger's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 2, 2026 and October 16, 2026 respectively.
