# ReadOn vs Graspd

The clearest difference is update cadence: ReadOn at every 6 days against Graspd's fortnightly. ReadOn also leads on iOS requirement (17.6 vs 26.1). On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. ReadOn sells 2 in-app purchases, starting at $4.99 per 7 days and Graspd sells 2 in-app purchases, starting at $14.99 per month. Whichever you choose, the download price is not the number that matters.
