Komoot is described as 'The key to the outdoors. Just plan your hiking, road cycling or MTB adventures in the planner, and be guided along every trail, track, road or path—even when you’re offline. Get your first region for free and say hello to your next adventure!' and is a GPS Navigation service in the travel & location category. There are more than 50 alternatives to Komoot for a variety of platforms, including iPhone, Android, Web-based, iPad and Android Tablet apps. The best Komoot alternative is OsmAnd, which is both free and Open Source. Other great apps like Komoot are OsmAPP, wanderer, RouteScout and Strava.
Walkmeter is just €10/year subscription vs €60 and does not gather personal data, just anonymised data (unlike Komoot who grabs all your health data, all your contacts and everything else Komoot can get its hands on). Great export/import capability. Walkmeter is a bit geeky though.
