# Signals Generator vs Paint Bid Pro

The clearest difference is device support: Signals Generator at 4 against Paint Bid Pro's 1. Signals Generator also leads on iOS requirement (15.6 vs 17.0). On price, ads and in-app purchases there is nothing between them.

Both are free to download. Signals Generator sells 10 one-off in-app purchases and Paint Bid Pro sells 1 one-off in-app purchase. Whichever you choose, the download price is not the number that matters.
