I wrote this application as part of an assignment back in March (2016) using the Android SDK and Google Maps API.
All restaurants in the UK are hygiene rated, this application allows users to search the database based upon the restaurants name, its postcode or the users location (obtained by GPS).
Alternatively the user can display the most recently added restaurants. The app returns the official ratings logos corresponding to its rating and in the case of searching by users location, displays how far away the restaurant is allowing routing to a destination.
Future improvements would be improving the speed the maps load (way too laggy), simpler rating logos on the maps and some aesthetic work on the UI. It would also be useful for the user to select which ratings to return ie only 5 star restaurants near them.
Here is a demo of the app…
Let me know what you think!
