How can I build a code to make a Tinder like function? Let's see:
1- The system gets user geolocalisation info by GPS from user smartphone.
2- This info is latitude and longitude
3- The system gets user radius in KM (example: 50 km radius)
4- Then the system look for cities nearby user inside 50 km radius (the radius is selected by the user)
Why don't you start by adding the cordova geolocation plugin to your app? This plugin allows you to get the user's location (longitude and lattitude) as you can see in the examples...
Finding a city next to the user's location might be a trickier, so i would consider using something like the google maps api. Maybe this is a good starting point here, as well as just searching for reverse geocoding.
