# Leaflet for Swift&Algorithm vs Java面试题库

The clearest difference is update cadence: Leaflet for Swift&Algorithm at every 8 days against Java面试题库's every 2 months. Java面试题库's advantage is review sentiment (80% vs 71%) and iOS requirement (16.0 vs 26.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Leaflet for Swift&Algorithm sells 1 one-off in-app purchase and Java面试题库 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
