I purchased procreate for my iPad Pro M1, and it allowed me to download the older iOS 6 version from my purchased apps list onto an iPad 4 on iOS 6 I have. I also tested it on an iPad 2 on iOS 5, and also different version identifiers with ADowngrader but the iOS 6 version is the only one available. Cracked with clutch and available for iOS 6.0+. This particular version is from October 2013.
