I was waiting for this for some time on macOS when it was announced and I came close to buying this. As soon as I saw the lifetime purchase price, at that point I'm wasn't quite sure I would purchase it at that price as an individual yet.
If it were discounted on release, then yes I would have purchased this. If it also supported Google Play at its original price then I would have happily purchased this today (Not sure if it would go through Apple's review process) and if I were part of a iOS shop team, then I would still buy it.
No question that this looks like a stunning native app for App Store Connect that was missing on macOS. At its original price for an individual it looks slightly too expensive for now.
