On the ios side of the world, the ipad 1 has old apps and runs ios 5.x. The ipad air2 is at 10.3.2 and will go only to 15.8.2. Stay old, keep your old apps. I keep old hardware that still runs. They do the basics that I got them for: music scores and lots and lots of book and article reading. And I haven't read them all yet. On the mac end: Supposedly, 32 bit apps stopped running post Mojave. No problem for old hardware that won't go past Mojave anyway, and I recommended sticking with Mojave to a friend who has 32-bit apps. Older mac apps I bought all are downloadable from the app store if they show in the app store under my purchases. And perhaps some are missing, if the apps shown have all been updated to run post-Mojave. I am actually trying to simplify things. (not easy for me) On the ios side of the mac app store, a lot of apps from 2013 and before are not downloadable. So, no Wild Berries and Herbs app for me. At least on a mac you can copy apps from the /Applications directory and sneakernet them. It seems that you need a third-party app to extract ios apps via a cable. Not going there.
