# Plain vs TextFlow

The clearest difference is update cadence: TextFlow at every 4 days against Plain's every 4 months. Plain's advantage is device support (3 vs 1) and iOS requirement (15.0 vs 17.0). On price, ads, in-app purchases and monetization model there is nothing between them.

Both are free to download. Plain sells 3 in-app purchases, starting at $4.99 per 7 days and TextFlow sells 5 in-app purchases, starting at $3.99 per 7 days. Whichever you choose, the download price is not the number that matters.
