# Keymagine vs Lengio

The clearest difference is review sentiment: Lengio at 100% against Keymagine's 55%. Lengio also leads on update cadence (every 3 days vs every 2 weeks) and rating (5.0 vs 4.8). Keymagine's advantage is ratings volume (170 vs 6) and iOS requirement (15.1 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Keymagine sells 7 in-app purchases, starting at $4.99 per 7 days and Lengio sells 3 in-app purchases, starting at $7.99 per month. Whichever you choose, the download price is not the number that matters.
