Verdict
The clearest difference is in-app purchases: U Gym at none against LeanLog's 3. U Gym also leads on ratings volume (14 vs 1). LeanLog's advantage is update cadence (every 8 days vs every 2 months). On price, rating, ads and device support there is nothing between them.

Both are free to download. LeanLog sells 3 in-app purchases, starting at $4.99 per month. U Gym asks for nothing beyond the download.
On the App Store both sit at effectively the same score — 4.9 for U Gym against 5.0 for LeanLog. That said, the two scores are not equally well evidenced: U Gym has 14 ratings behind it against 1, so its average is the more settled of the two.
U Gym ships an update every 2 months, LeanLog every 8 days. The most recent releases landed on September 16, 2026 and October 1, 2026 respectively.
