# Flex AI Workout Trainer & Log vs Thicc App

The clearest difference is review sentiment: Thicc App at 100% against Flex AI Workout Trainer & Log's 69%. Thicc App also leads on rating (5.0 vs 4.6). Flex AI Workout Trainer & Log's advantage is ratings volume (2.4K vs 2) and update cadence (every 9 days vs every 2 months).

Both are free to download. Flex AI Workout Trainer & Log sells 8 in-app purchases, starting at $12.99 per month and Thicc App sells 11 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.

That said, the two scores are not equally well evidenced: Flex AI Workout Trainer & Log has 2.4K ratings behind it against 2, so its average is the more settled of the two.
