Boon is a property-tech product built around a practical promise: make apartment-building access simpler, safer, and easier to manage from a phone. Our work on the product covered the iOS and Android apps as well as ongoing maintenance of the Java backend that supports device communication, user flows, and building operations.
What the product includes
- HD intercom audio and video calls from a phone
- Smart door and gate opening from the mobile app
- Visitor history with screenshots and cloud video access
- Quick actions, Bluetooth-based entry, and building features such as cameras, packages, parking, elevators, and payments
What makes the system interesting
The live product and local iOS repo show that Boon is much more than a remote door-opener. The current iOS app is a native Swift codebase with SwiftUI, MVVM, a Redux-like app store, async networking, VoIP push handling, CallKit, and native PJSIP integration over TLS for intercom calls. That gives the resident-facing app a clean mobile experience while still dealing with very hardware-adjacent problems under the hood.
Why the work mattered
This kind of product has to feel simple in the hand while juggling a lot in the background: mobile permissions, device state, intercom timing, access control, notifications, and backend coordination. Supporting both mobile platforms while continuing to maintain the Java backend meant keeping the whole system dependable, not just shipping screens.
Why it stands out
Boon stands out because it sits at the intersection of mobile UX, building hardware, and operational reliability. It is a consumer-facing app, but it behaves more like infrastructure. That combination makes it the kind of product where engineering quality has a direct effect on everyday trust.
