# Fast Rhythm vs Ora

The clearest difference is iOS requirement: Ora at 16.1 against Fast Rhythm's 18.6. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Fast Rhythm sells 2 in-app purchases, starting at $4.99 per month and Ora sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
