# Flex vs Gym log

The clearest difference is rating: Gym log at 4.9 against Flex's 4.2. Gym log also leads on ratings volume (838 vs 5) and review sentiment (99% vs 75%). Flex's advantage is in-app purchases (none vs 7) and iOS requirement (14.0 vs 16.2). On price, ads, monetization model and device support there is nothing between them.

Both are free to download. Gym log sells 7 in-app purchases, starting at $6.99 per month. Flex asks for nothing beyond the download.

Gym log holds the better App Store score, 4.9 against 4.2. That said, the two scores are not equally well evidenced: Gym log has 838 ratings behind it against 5, so its average is the more settled of the two. Written reviews point the same way: 75% of Flex's written reviews are positive against 99% of Gym log's.

Flex ships an update fortnightly, Gym log every 4 days. The most recent releases landed on September 11, 2026 and September 24, 2026 respectively.
