Verdict

The call

The clearest difference is rating: ErgData at 4.7 against ThinkFIT's 3.7. ErgData also leads on update cadence (fortnightly vs every 3 months) and ratings volume (6.3K vs 3). ThinkFIT's advantage is iOS requirement (12.0 vs 16.0). On price, review sentiment, ads and in-app purchases there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

ReceptionRating · Positive reviews · Number of ratings

ErgData holds the better App Store score, 4.7 against 3.7. That said, the two scores are not equally well evidenced: ErgData has 6.3K ratings behind it against 3, so its average is the more settled of the two. Written reviews complicate that: 47% of ErgData's written reviews are positive against 50% of ThinkFIT's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

ErgData ships an update fortnightly, ThinkFIT every 3 months. The most recent releases landed on November 6, 2026 and November 3, 2026 respectively.
