kjeopardy VS pure-maps

Sure. You're right, PyQT is not available for KF5 (although there is a fork of it which I did not yet try out). However you can use PySide 2 and write your UI with Kirigami in QML. If you want to you can check out my crappy code at https://github.com/KaratekHD/kjeopardy

I am assuming this is talking about Android, but for Mobile Linux, Pure Maps has been awesome: https://rinigus.github.io/pure-maps/

I have been successfully using it for over four months now for both car an bike navigation.

Pure Maps with OSM Scout Server for offline mapping and geolocation

Pure Maps (map/navigation app) -- works, but lacks some features.

Thanks. I opened an issue and it seems to be a bug.

OSMAND (like any Android app) is unlikely to be ported, but we have PureMaps, which is quite solid: https://github.com/rinigus/pure-maps, and GNOME Maps has been improving lately, too.

Ok, this one I'll agree with for the most part. Well, not to the same extent but whatever. Gotta say though, the Sailfish and Plasma Mobile communities have been cross-pollinating tech quite a bit lately; Sailfish Connect is based on KDE Connect, while Pure Maps was ported to Kirigami (and UUI for Lomiri). Yes, many of the mobile Linux projects have historically been rather isolated from each other. However, this is an area which the Qt-based ones have been getting better at rectifying for a while now. Hopefully this continued cross-pollination continues, as the entire mobile Linux ecosystem will be all the better for it.

For navigation there's Pure Maps: https://github.com/rinigus/pure-maps
