This app is not a database, it only links to the website; and will just sit & spin if you don't have Location enabled when you launch it. As it requires an active internet connection, if you are in a remote location you are SOL. My suggestion wold be build the app and use SQLite to at least store selected or nearby locations..
Nothing but a link to the website which is a pain to browse on a mobile device.
Literally Just a Link to the Website I added a bookmark to the page on my home screen and now I do not need the app.
