I am in the same situation. My dad lost his vision recently and can’t interact by touch screen due to nerve damage from a life of physical labor. I tried a game controller with switch control on a iPhone but that was too complex, so now he’s focused on things Siri makes possible. What got him recently is a phone menu asking to dial digits. We solved this by programming the number into his phone to automatically pause and then dial the right numbers to get to the operator. I now think a t9 keypad accessory for iPhone would be the best for him but I haven’t been able to find one. I am hopeful about the new simplified interface on iOS being released in iOS 17. Design for voice isn’t present in many apps and the complex layouts aren’t easy to map in your mind. I think some Siri Shortcuts could be helpful for your mom. My dad is diabetic so he uses a ‘hey siri check my blood’ to know what he’s at. In his case he needs full time care at this point. For entertainment, he listens to books on tape from a tape player with giant buttons he got from the association for the blind. He got an audible subscription as a gift, but uses the tape player instead of trying to figure out the tech.
