Verdict

The call

The clearest difference is ads: Flex AI Workout Trainer & Log at none against JEFIT Workout Plan Gym Tracker's shown. Flex AI Workout Trainer & Log also leads on review sentiment (69% vs 57%). JEFIT Workout Plan Gym Tracker's advantage is ratings volume (47K vs 2.4K) and rating (4.8 vs 4.6). On price, update cadence, in-app purchases and monetization model there is nothing between them.

Both are free to download. JEFIT Workout Plan Gym Tracker sells 13 in-app purchases, starting at $6.99 per month and Flex AI Workout Trainer & Log sells 8 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.

ReceptionRating · Positive reviews · Number of ratings

JEFIT Workout Plan Gym Tracker holds the better App Store score, 4.8 against 4.6. That said, the two scores are not equally well evidenced: JEFIT Workout Plan Gym Tracker has 47K ratings behind it against 2.4K, so its average is the more settled of the two. Written reviews complicate that: 57% of JEFIT Workout Plan Gym Tracker's written reviews are positive against 69% of Flex AI Workout Trainer & Log's, so the app with the better star average is not the one people write more warmly about.

UpkeepUpdate frequency

JEFIT Workout Plan Gym Tracker ships an update every 5 days, Flex AI Workout Trainer & Log every 9 days. Both last shipped on October 17, 2026.
