Sentra

The Lost Dev

About this app

Sentra is the real-time map for pedestrians — powered by people who are actually there. Sentra shows you what’s happening on the ground right now. Busy areas. Road closures. Street performers. Food trucks. Water refill points. Reported in real time by other people in your city, verified by presence.

How it works Drop a quick pin when you spot something worth sharing - a blocked pavement, a crowd, a hidden gem. You must be physically there to post, so everything on Sentra is fresh, real, and location-verified.  Browse the live map to see what’s around you. Confirm reports you can see yourself, or dismiss ones that are no longer there. The more people contribute, the smarter the map gets.
