# AZNANA vs Flat Machine

The clearest difference is ratings volume: AZNANA at 444 against Flat Machine's 68. On price, rating, review sentiment and update cadence there is nothing between them.

Both are free to download. AZNANA sells 6 one-off in-app purchases and Flat Machine sells 4 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
