       | unfortunately.
       | 
       | Still, it's very exciting to see they started from a "Helicoptor
       | Router" [1] five years ago! The author clearly knew what they
       | were doing.

       | 
       | I've switched to Osmand [1] and BRouter [2] (both available on
       | F-Droid) and nerver looked back. BRouter on Android is a bit
       | tricky to set up (you need to download routing tiles in addition
       | to the map files through a really ugly UI), but once you're done
       | it's the best bike navigator I can think of (and it's really
       | fast).
       | 
       | The BRouter profiles are highly customizable, check out Poutnik's
       | repositories [3] for examples. Some of his profiles and many
       | others con be tested on https://brouter.m11n.de/ (german).

       | Other F-Droid users here might know that the previously existing

       | files. Perhaps they're unable to continue hosting. (In any case,
       | I appreciate their work.)
       | 
       | So, it's exciting that there's another option available again.

         | EDIT: Nevermind it was just the new app feel. It's about the
         | same. (but still good)

       | For anyone wondering, this is a fork of the rather popular app
       | maps.me, which also uses Openstreetmap but started monetizing via
       | increasingly intrusive ads in the past.

         | Just a glance at maps.me makes it clear why a fork is needed.
         | They've launched a cryptocurrency which seems like a pretty
         | massive red flag: https://maps.me/token/

         | I briefly looked over the github commits earlier when this fork

         | commits just to remove all those nasty integrations.

         | Looks like this fork is in better hands.
