Both are free to download. U sells 2 in-app purchases, starting at $7.99 per month. Leaf asks for nothing beyond the download.
Leaf holds the better App Store score, 5.0 against 4.4. That said, the two scores are not equally well evidenced: U has 198 ratings behind it against 1, so its average is the more settled of the two.
Both ship on a similar rhythm, roughly fortnightly. The most recent releases landed on October 14, 2026 and October 13, 2026 respectively.
