I'm slowly learning flutter and building apps for Android and IOS. As my first app I'm just testing a simple checklist app for my family members. I know that if you build it, you can ship it as an apk for android users without the need to do anything Play Store related.
But what about iPhone users? I also don't need to do anything regarding the App Store and I certainly don't want to pay 99USD a year to just learn app development (As I'll maybe buy a mac in the future if I consider using Swift). I heard that it's possible using TestFlight but there was a 90 day build limit and other stuff (probably the license) so I was wondering if there's a way to download apps like .apk files and install them without limitations from apple?
I've also seen that there's .ipa files, but I believe those are just for Jailbroken iPhones.
