# Simplex vs MyFormulae

The clearest difference is ads: MyFormulae at none against Simplex's shown. MyFormulae also leads on iOS requirement (13.0 vs 26.0). On price, in-app purchases and device support there is nothing between them.

Both are free to download. Simplex sells 1 one-off in-app purchase and MyFormulae sells 6 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
