# Off vs Lean

The clearest difference is in-app purchases: Lean at none against Off's 1. Lean also leads on ads (none vs shown) and update cadence (fortnightly vs every 4 months). Off's advantage is ratings volume (763 vs 1) and device support (3 vs 1). On price and iOS requirement there is nothing between them.

Both are free to download. Off sells 1 one-off in-app purchase. Lean asks for nothing beyond the download.

Lean holds the better App Store score, 5.0 against 4.6. That said, the two scores are not equally well evidenced: Off has 763 ratings behind it against 1, so its average is the more settled of the two.

Off ships an update every 4 months, Lean fortnightly. The most recent releases landed on September 20, 2026 and September 24, 2026 respectively.
