# MidiQuesti vs Aparillo

The clearest difference is review sentiment: Aparillo at 89% against MidiQuesti's 10%. Aparillo also leads on rating (4.9 vs 1.5) and ratings volume (506 vs 11). MidiQuesti's advantage is update cadence (weekly vs every 4 months) and iOS requirement (10.3 vs 17.6). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. MidiQuesti sells 10 one-off in-app purchases and Aparillo sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
