IF DS was an App i’d agree but its browser based and it zooms in waayyy too far on initial filtering for your location … I prefer Guardian (Altitude Angels which powers Drone Assist as well) and the ability to log your flight is very useful. Not sure DS does that …
And I am not knocking DS its great for what it does but the info on the Airspace restrictions in Guardian or Drone Assist is more informative. DS simly says its a Class D CTR airspace but no details of it whereas DA will show you the full restriction …
