# Input vs Erla

The clearest difference is device support: Erla at 3 against Input's 1. Erla also leads on iOS requirement (15.0 vs 18.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Input sells 8 in-app purchases, starting at $2.99 per month and Erla sells 2 in-app purchases, starting at $12.99 per month. Whichever you choose, the download price is not the number that matters.
