# Check Engine Chat vs PlainAuto

The clearest difference is iOS requirement: PlainAuto at 17.0 against Check Engine Chat's 26.2. On price, ads, in-app purchases and device support there is nothing between them.

Both are free to download. Check Engine Chat sells 1 one-off in-app purchase and PlainAuto sells 3 one-off in-app purchases. Whichever you choose, the download price is not the number that matters.
