OpenSky - App for Drone Flyers

works well

The app itself is good. Simple minimal Google-looking UI since it's from the same parent company as Google, and uses your Google account. Does the job simply as well, showing you any airspace restriction, and sort of tells you why. But you aren't going to get any response from support services if you have an issue. It's not like you'll have any issues. But if you do, they don't care nor respond, probably bc it's not actually Google, who you'd normally get great help from. Great app, bad service.
