Privacy-focused mobile app for UK house buyers and renters to easily bookmark property listings and help understand the market.
The UK housing market post-COVID, post-Brexit, post-Truss has been unpredictable to say the least. For those looking to buy or rent their next home, the challenge has never been greater, with soaring prices and a cost of living crisis upending the property landscape. How do you navigate this chaos to discover your perfect place to live?
Enter Property Tracker, a privacy-focused mobile app on iOS and Android developed by Add Jam to be your trusted companion in the home search journey.
Born from our own frustrations with the complexities of property search, Property Tracker empowers buyers and renters with tools to organize, personalise, and optimise their home search experience:
In an age where personal data has become currency, Property Tracker champions a privacy-first approach. All your saved listings and notes are stored exclusively on your device, never leaving the safety of your own phone. Your home search journey remains yours alone.
The Add Jam team built Property Tracker as a cross-platform app using React Native, allowing for seamless deployment to both iOS and Android devices from a single codebase. The app architecture is designed around offline-first principles, ensuring full functionality and data persistence even without an internet connection.
One of the key challenges we solved was structuring the data models to flexibly handle the diverse property listing formats from various portals while still enabling efficient search, filtering, and comparison of saved properties. Our solution provides a smooth, intuitive user experience for organizing and managing the complexities of a property search.
Ready to take control of your property search and stay organized through the home buying or renting process? Download Property Tracker today for iOS or Android and start your journey to finding your perfect place with peace of mind.
To ensure maximum visibility and downloads for Property Tracker, we implemented comprehensive App Store Optimization (ASO) strategies for both iOS and Android platforms.
