MapaTrhu · 02
See the home and its surroundings.
The map and listings stay together. Explore an area and a selected home without losing context. The app distinguishes exact and approximate locations.

Why the product keeps changing
The product grew from a shared map into a data platform, then a simpler everyday interface. Each stage addressed a different obstacle in property search. Screens shown here belong to V3.
V1
Bring listings together
The starting point was fragmented property search. A shared map made it possible to view listings alongside their location.
V2
Build the data foundation
A list of adverts cannot explain a price on its own. The next stage developed the data work needed for more useful comparisons.
V3
Less friction at the surface
The current production version connects search with the property detail. Behind the interface, data processing and trained models support the figures, with their limits kept visible.
Numbers you can put in context
A product counter and a model evaluation answer different questions. These figures include their method and date. Live product totals will change.
