It would certainly work on a larger airsoft/ Milsim environment (ground zero weekender would also benefit from this). If it could be adapted to be used on an Apple Watch/ Garmin etc then it would be a brilliant app. No getting your phone out every 5 mins
I’ve been listening to a lot of kasbian at the moment while driving. Always a great mix of music (even if I am a bit biased being from Leicester ha ha)
