Useless

This apps assume everybody should live in Aberdeen! What is the point of having geolocation activated, then?

I can’t get past the legal disclaimer screen.

I can’t get past the legal disclaimer screen. Nothing happens when I press “agree.”

Update issues

Since the app was updated I can no longer rotate the screen to make it wider for the world view. Also no place to report this problem as all links on the page don’t work.

Love it

I've been using this on my iPhone for a while and I saw it now on the App store. Great job and a great tool.
