I love this piece of software and I use it every day. It is a simple note taking application which syncs across all of your devices. It is a self-hosted single-page web app that runs on a PHP server and does not require a database.
I run a copy on my phone and a copy on my laptop.
- I used
Add to homescreenon my phone so that it gets an icon and launches full-screen. - I'm using this site-specific browser trick to run the app in its own window on my desktop.
The app was built by Kaspars Dambis and I forked it to modify the design and add some usability tweaks like ctrl-S to force sync. You can find the source code of my fork on GitHub if you want to install it yourself.
