A great idea but…
I think this will be a useful app when the database is populated but, for the mean time, it’s not functional.
There are a number of administrative glitches too. It keeps logging me out and it’s unnecessarily complex to log back in. In addition, despite giving permission to use location, it always starts by placing me in London.
In my enthusiasm, I purchased the premium version. Unless the database gets populated very soon, I won’t renew.
It’s a shame to rate an app at only 3 stars because I know how hard it must be to develop something as potentially useful as this. I will hang on for now and see what happens.
