Fast than Light (FTL) would fall into that category for me. It has a lot of rouge-like elements, the store is the same but all the details change with each new game so tons of replayability. iPad only, though with the screensize of the new xs and xs max they might want to reconsider that. Also, just recently released for iOS is Stardew Valley. I haven't played it (usually the only time I'll play anything is on a long flight) but it was extremely popular on other platforms and is getting rave reviews so that might be worth trying.
