# SD Inclinometer vs Lean

The clearest difference is in-app purchases: Lean at none against SD Inclinometer's 1. Lean also leads on ads (none vs shown) and update cadence (fortnightly vs every 2 months). SD Inclinometer's advantage is device support (3 vs 1) and iOS requirement (13.0 vs 17.0). On price there is nothing between them.

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

SD Inclinometer ships an update every 2 months, Lean fortnightly. The most recent releases landed on October 8, 2026 and October 11, 2026 respectively.
