Linux phones are becoming a thing, Recently I got a PinePhone which is capable of running Anki Desktop. Unfortunately, GUI doesn’t work very well on small screen. PinePhone screen resolution is 1440x720, not different from laptop decade ago, or so. I think Anki GUI which is for the most part not very complicated, could fit, look good, and be comfortable with some tweaks. Below is screenshot of Anki version 2.1.15 running on PinePhone.
