# Mech Boa vs EVO

The clearest difference is rating: EVO at 4.6 against Mech Boa's 3.7. EVO also leads on review sentiment (52% vs 26%) and ratings volume (6.4K vs 149). Mech Boa's advantage is in-app purchases (none vs 1) and update cadence (every 5 days vs every 2 months). On price, ads, device support and iOS requirement there is nothing between them.

Both are free to download. EVO sells 1 one-off in-app purchase. Mech Boa asks for nothing beyond the download.

EVO holds the better App Store score, 4.6 against 3.7.
