Note-taking apps for desktop, web and mobile

November 2021

Joplin

• Joplin is pretty great because it syncs between desktop and mobile, using any backend cloud of your choice.
• Joplin doesn't have an official web app, probably because it would be re-inventing the wheel.
• It does have this web client (alternate link), but it's not being maintained.
• There are many forks, have any been worked on?
• It did have nextcloud integration, but this has not been maintained.
• To do: Check those forks too
• Nextcloud can be self-hosted (requires some work), or it can be hosted in the cloud by a provider.

Tomboy

• Tomboy appears very linux-centric, although it has clients for Windows and Mac too.
• It has an Android app, TomDroid.
• It has a WebDAV plugin for publishing to the web
• No web actual app

Evernote

• Proprietary software
• Charges actual money
• Irritating business practices
• Free version only allows two devices, which isn't enough

Org mode

• orgmode.org
• No web app

Colornote

• Works brilliantly on Android
• Super fast for short notes

All the homebrew packages I've installed on Mac OSX

I've used `brew install ....` many times, but now I'm regretting it because:

• `brew update` takes so incredibly long to run, and downloads lots of unnecessary git history
• `/usr/local/Cellar` is 3.8Gb big and I'm short on disk space
