I hajack your quiestion since I think it is interesting question...

I desperately need below apps if I want to replace my current phone with librem. The list shows that I can't fully replace. For me librem will be used as prof & concept and playing. Replacing main usage I doubt cause of.

* Bankid/Swish (Guess what even geeks need to pay it bills and buy food!!!)
* Vastrafik (Local Bus ticket app)

Below can be done by the community:

* Bitcoin wallet (I mean seriously why does we STILL not have a some kind of Linux mobile client for this!?
* Monero client (This looks promising at least)
* Spotify client (Yes, even geeks listen to commercial music and are willing pay for it) Spotify has killed libspotify. What comes next is unknown. Maybe their webapi can be used in some way not sure how and if possible...
* Fully functional telegram client look at the android version.
* A decent and working podcast client. gpodder is really broken in
SFOS. Probably cause maintainer has moved on. We need a replacement for this.

Of course I could replace spotify premium with some other online music stream IF there is some who has API library for Linux. But I doubt there is.

Now this could change if Jolla enters the building and officially port SFOS+dalvik to core Linux without libhybris/android kernel blob
