# Flex vs Barbell AI

The clearest difference is review sentiment: Barbell AI at 100% against Flex's 50%. Barbell AI also leads on rating (5.0 vs 3.0) and ratings volume (15 vs 2). Flex's advantage is iOS requirement (10.0 vs 14.0). On price, ads, in-app purchases and monetization model there is nothing between them.

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

Barbell AI holds the better App Store score, 5.0 against 3.0. That said, the two scores are not equally well evidenced: Barbell AI has 15 ratings behind it against 2, so its average is the more settled of the two. Written reviews point the same way: 50% of Flex's written reviews are positive against 100% of Barbell AI's.
