maybe old news for some but I recently found the Komoot app and it looks pretty good! I wanted to be able to navigate a 20 mile trail that is completely new to me and I do not have a Garmin etc....and I am generally not that interested in such devices so I was looking for a way to run that trail without getting lost whilst not having to invest in tech I would rarely use. Komoot is a mapping application running on Android with the option to select a specific sport...obs in my case MTB...….which then gives access to a fair number of graded MTB trails within the app but also enables the download of a GPX file from somewhere like Trailforks etc. As it happened the trail I want to ride was already on the app. You get one region ( in my case South Powys...South Wales UK to cover the Brecon Beacons National Park) free. You can apply for additional regions or pay a single fee for the lot ( £30). The trail I want ( The Gap) is loaded ready for next weekend when I am in the Brecon Beacons National Park...….so I have not as yet actually used it but it tells me Navigation is aided by voice commands etc similar to Blevo. I just need to find a safe way to mount my phone on the bike now!
