Honestly, I haven’t really changed my mind about Apple. I do (did) use the app I lost for acidemic purposes and really regret the lose. However, I did see it coming. Apple warned developers to update a long while ago. The developer had already been showing signs of disappearing for some time now. I’ll continue to use my iPad Pro/MacBook. Being able to carry most of my research library with me has been incredible. I’ve started to slowly buy into a different app whose developer has been developing their product since way before iPhones and iPads exstisted. I probably should have went with them to start with.
Yes, I wish Apple would continue to support 32 bit apps but, I also see this as a way to get serious developers ro keep their apps up to date. As technology advances we don’t have any guarantees of the future of any app.
