Ask HN: App and input device recommendations for someone with ALS

My friend has recently been diagnosed with ALS. His symptoms started about 8 months ago. The disease has progressed heartbreakingly quick, to the point where it's getting harder for him to use his phone and laptop. For example, pinch-to-zoom in Maps is now pretty much impossible, and he mentioned that he is only able to use one finger typing.

Does anyone have any suggestions in terms of both hardware - mice, keyboard and other input devices for a Windows laptop - and software - apps to make navigating his Android (Samsung S22) phone easier?
