LetDem is a mobile app that turns everyday drivers into a live parking network. When someone leaves a spot, they share it with a single photo. Nearby drivers see it on the map, choose it and drive straight there.

Problem*
In busy cities, the hardest part of a trip often comes at the end. Drivers circle block after block looking for a free space, burning fuel, time and patience, and adding to the congestion they’re stuck in. The information that would help already exists: someone nearby is about to pull out. But nothing connects the driver who is leaving with the driver who is arriving.
My Approach*
1. Make sharing take one tap.
The whole network depends on drivers giving away information while they’re busy getting into their car. If sharing feels like work, nobody does it.
I cut posting down to one action: take a photo. The app detects and fills in the address, and the driver picks the zone type (free, blue, green or disabled) with a single tap.
The photo has to come from the camera, not the gallery. That keeps the effort low and makes it hard to post fake spots.
2. Build trust into the loop.
A shared spot is only useful if it’s still there when you arrive. When drivers reach a spot, they confirm it with one tap: I’ll take it, In use, Not useful or Prohibited.
Each answer updates the map in real time. The driver who shared the spot is notified when it’s taken and earns points, scaled by how congested the area is. Accurate sharing gets rewarded, and the map keeps itself clean.
3. Design for the driver’s seat.
Drivers can only glance at the screen, so the map does most of the work. As they get close to their destination, free spaces appear along the way, so they can park before they arrive.
Speed limits, arrival time and turn-by-turn directions stay visible. Alerts for cameras, accidents, police checks and zones closed to their car’s emissions tag show up only when relevant, and drivers choose which alerts they see.
Results*
I designed LetDem end to end, from registration to rewards. More than 20 features sit within four clear flows: share, find, drive and earn. Each driver is both a seeker and a giver, so every trip makes the network more useful.
Success metrics to track after launch: time spent searching for parking, the share of spots confirmed with I’ll take it, and how often drivers share again.
