How to expose any port to the Internet without exposing your private IP (for free).
Journey of finding ideal note-taking app TL;DR: If you want to transfer your bear notes to markdown goto Move your bear notes, if you want to emulate Bear multi-tagging check Multitagging support. Once upon a time I was using Bear.app for writing and organizing notes. It had really good features like multi-tagging and couple of other nice features like pseudo markdown support. Unfortunatelly a lot of things were bugged, developers slow in fixing them so I decided to move my notes from Bear to other platform.
