Development of a mobile application in 9 days

This customer needed me to rapidly build a prototype to undergo market testing. Owing to my 10 years of experience as a developer, I managed it! Here's what I was able to draw up:

• A geolocation feature that allows you to see people around you, even if their app is offline
• Uploading a profile picture

If you have 5 minutes, feel free to download the app iOS or Android.
