# MemPin vs 信析

The clearest difference is update cadence: MemPin at every 10 days against 信析's every 2 months. MemPin also leads on iOS requirement (12.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. MemPin sells 3 in-app purchases, starting at $0.99 per month and 信析 sells 3 in-app purchases, starting at $0.99 per month. Whichever you choose, the download price is not the number that matters.
