# O Sebo vs Leaf

The clearest difference is in-app purchases: O Sebo at none against Leaf's 7. O Sebo also leads on iOS requirement (11.0 vs 16.4). Leaf's advantage is update cadence (every 3 days vs every 8 days) and ratings volume (9 vs 1). On price, rating, review sentiment and ads there is nothing between them.

Both are free to download. Leaf sells 7 in-app purchases, starting at $2.99 per month. O Sebo asks for nothing beyond the download.

On the App Store both sit at effectively the same score — 5.0 for O Sebo against 5.0 for Leaf. That said, the two scores are not equally well evidenced: Leaf has 9 ratings behind it against 1, so its average is the more settled of the two. Written reviews split almost evenly too, at 100% and 100% positive.

O Sebo ships an update every 8 days, Leaf every 3 days. The most recent releases landed on October 6, 2026 and October 19, 2026 respectively.
