Verdict

Both are free to download. Flex AI Workout Trainer & Log sells 8 in-app purchases, starting at $12.99 per month and Dropset sells 3 in-app purchases, starting at $4.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

Flex AI Workout Trainer & Log holds the better App Store score, 4.6 against 4.4. That said, the two scores are not equally well evidenced: Flex AI Workout Trainer & Log has 2.4K ratings behind it against 96, so its average is the more settled of the two. Written reviews complicate that: 69% of Flex AI Workout Trainer & Log's written reviews are positive against 78% of Dropset's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

Flex AI Workout Trainer & Log ships an update every 9 days, Dropset every 4 days. The most recent releases landed on October 20, 2026 and October 15, 2026 respectively.
