It seems like it’s got great potential but there are just way too many issues right now. It doesn’t work at all on my iPad running iOS 17. It just freezes. On my phone running iOS 18, it’s mostly functional but buggy. No matter what I click it says my subscription that I set up is expired. (I figured this out but there should really be some tool tip that explains this.. I put the due date as yesterday since it was the most recent due date. It considers that expired. So anyone else with a problem, this might be why.) There are also “Custom” options for “Payment method” and “Subscription type”, but then nowhere to input what the “Custom” is. This last thing is probably just personal preference, but I don’t care for the only way of viewing the subscription to be the edit screen. I’d prefer having a screen that lists all of the things I selected when I set it up/last edited it, with a button to edit it if needed. It’s also really annoying that every time I leave that screen for a subscription, it says it’s updated successfully (when I’ve changed nothing) and does the little haptic thing. (Which I know you can turn haptics off in the settings, but I don’t want them off for when I’m actually editing something. But even though viewing is not editing, Subby considers it to be.)
Edit to add response to dev: Sorry for not being more clear. My iPad is on iPadOS 17.7, so later than 17.6, and I’m having that issue. (And just to further clarify: the “iOS 18” is actually iOS 18.0.1.)
