They are also very Chinese and closed and without a proper Google Play store. I used a HiSense 5c pro as daily phone (hope I have the name right).
Bought it because I’m quite interested in eink. It is interesting to use and it is really usable. It is ok to read text on. I was not able to root it and was thus a bit locked in. The lock screen couldn’t be adapted to my liking and I did not fully trust in what spying it might be doing (like Google location tracking and such).
We run Taiga and it seems to work fine.
If you want to link to external sources in a structured way and you don’t mind tweaking the looks, SolidOS (ot another SOLID app) has a task list/tracker.
I keep my personal tasks in org-mode or org-roam.
