New purchase immediately offers upgrade at full price. – Tap Forms Organizer Review

There seem to be too many versions. I use tap forms on MacOS and wanted to be able to use it on iOS as well. But when I buy, it immediately encourages me to upgrade to tap forms 5. Don't make your users figure out which version of your app they need.
