Yeah, that was one reason to go with Joplin.

I few month ago I switched, after a decade from the iphone to Android.

So I need new Apps. I was looking to replace the iphone apps with open source apps on the Android. I tried many apps over weeks. For the notes app I decided to use Joplin, but for me it was the best. Open source, encrypted, no subscription etc. And I can use it on my phone, tablet, Windows and Linux PC.

And I can export all of my notes into different data types. If I ever wanna switch to another app it would be really easy.
