Mobile Linux user, the two best maps I've found are mepo, and osmin (similar to OSMAnd on the goolag os). puremaps is also decent, and closer to what you expect with something like google maps in terms of feature parity, but it's much heavier ( not good on pinephone's anemic cpu and 3G of ram :( ). KDEs marble is interesting, but not a good mobile interface.
Iโm sick of using google maps, they started putting gigantic ads for stores on the map and Iโm tired of them tracking me.
Yet you use the Goolag kernel? User, how could you!
