# OASA vs Lemon

The clearest difference is rating: Lemon at 3.7 against OASA's 2.7. Lemon also leads on iOS requirement (15.6 vs 17.5). OASA's advantage is review sentiment (14% vs 0%). On price, ratings volume, update cadence and ads there is nothing between them.

Both are free to download. Neither carries in-app purchases, so what you see is what you pay.

Lemon holds the better App Store score, 3.7 against 2.7. Both are backed by a comparable volume of ratings — 3 and 3 respectively.
