I have been using Auer Notes for a couple of years and it's just awesome in its simplicity. It started as a way to help the developer, a friend of mine, and after testing it for a few week I switched to it from my standard Apple Notes.
Auer Notes is a plain text, simple, and private note taking app for Mac, and my friend just made it open source.
I've been getting myself deeper and deeper into developing macOS and iOS apps, but I'm a beginner there. I might take Auer Notes' code and give it a go, but maybe there are some of you out there with the ability to finish it, making version 1.0 a reality.
Yes, Auer Notes is now open source. Let's go finish it.
