Emacs org-mode is one of the better organization tools with batteries included.

For someone who is disciplined, organized and feels limited by their current tooling, Emacs will probably work great like these anecdotes. If having the discipline itself is a problem then Emacs is probably not the right choice to start with because of the learning curve and the friction due to sub-optimal experience on phone.

That said, I do recommend to give it a go. On Android, Orgzly + Syncthing is good enough to get started.
