# Mayday Memory vs Echo Dig

The clearest difference is update cadence: Echo Dig at every 3 weeks against Mayday Memory's every 2 months. Mayday Memory's advantage is iOS requirement (13.0 vs 16.0). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Mayday Memory sells 11 one-off in-app purchases and Echo Dig sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
