At Smart MasterKey, we know that security is only as strong as its usability. That’s why we’ve redesigned our mobile app interface, and rebuilt its foundation to deliver a faster, more adaptive experience for both users and administrators.
Whether you manage a few access points or a portfolio of properties, the new Smart MasterKey mobile UI is built to reduce friction and speed up day-to-day operations.
Designed for Simplicity. Built for Scale.
Previously, our mobile interface worked well for large-scale setups, but felt underwhelming for smaller environments—especially when managing just one or two doors. You told us this. We listened.
What’s new:

- Single Access Point
The app now opens straight to the device view—no extra taps, no confusion. You get instant control over access, users, and logs. - Two to Three Access Points
A streamlined card layout presents each access point with clear visuals, lock status, and quick actions giving you a fast operational overview. - Refreshed Device Details
We’ve updated the layout to surface core actions (unlocking, PIN, users, location) more clearly. Visual and map improvements make navigation intuitive even in complex facilities.
Powered by Kotlin Multiplatform: One Codebase. Faster Progress.
We’ve rebuilt our mobile apps using Kotlin Multiplatform. This means we now use a single codebase for both iOS and Android. It speeds up development, reduces bugs, and ensures new features reach all users at the same time. Alongside this refactor, we reviewed and improved all data models. The result is a faster, more stable app with better caching and performance. It also sets a stronger technical foundation for future updates.
Why This Matters

This update matters because it makes your work faster and easier. Security managers can respond to incidents quicker and handle daily tasks more smoothly. Real estate teams get faster tenant onboarding and spend less time on manual admin. For C-level leaders, it shows Smart MasterKey is focused on scalable tech, higher product quality, and long-term value.
Get the Update
The new app will be available on both the App Store and Google Play. Simply update to the latest version to start using the new interface.
