# Lacha App vs Koin

The clearest difference is rating: Koin at 5.0 against Lacha App's 4.2. Koin also leads on ads (none vs shown) and monetization model (free vs ad-supported). Lacha App's advantage is ratings volume (11 vs 1) and iOS requirement (15.0 vs 18.6). On price, update cadence, in-app purchases and device support there is nothing between them.

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

Koin holds the better App Store score, 5.0 against 4.2. That said, the two scores are not equally well evidenced: Lacha App has 11 ratings behind it against 1, so its average is the more settled of the two.
