organice is front end that runs entirely in a mobile or desktop browser that allows you to access and edit org files easily with a touchscreen or mouse and keyboard. It obviously doesn’t have full org mode functionality, but it does a have a calendar view.
All you have to do is navigate to organice.200ok.ch in your phone’s browser and then pin it to your start screen. The PWA is downloaded and you can now access a remote webdav server with the locally saved front end of organice. No data is sent to organice, the only function of the website is to give you an easy place to download the PWA to your device using a web browser.
I love love love love org mode, it is just simple yet so powerful and there really is nothing else like it, I can’t really recommend anything else in good conscience here, especially since most other options (except for logseq logseq.com which I am not sure does everything you want?) are commercial and who knows what the hell will happen when the company goes out of business or is bought out by someone else?
I recommend Spacemacs or Doom emacs as a nice starting point for emacs, or you can just start with basic emacs and build it yourself as org mode is included in the default distribution of emacs.
An additional thing to think about, there is an android release of emacs coming up, so org mode might get much more accessible on the go in the future!
No worries if you aren’t interested, I am just providing some additional context.
