Zerene
Zerene is a revolutionary smart mouthguard and app ecosystem that tracks and treats bruxism. It uses gentle biofeedback to stop teeth grinding and improve sleep quality.
The Problem
Bruxism affects millions, leading to chronic TMD pain, dental attrition, and severe sleep deprivation. While Zerene had perfected the hardware—a device capable of sensing clenching via pressure—they required a high-performance mobile "command center."
The challenge was twofold:
- Seamless IoT Integration: Maintaining a persistent, ultra-low-energy Bluetooth connection during 8-hour sleep cycles.
- Complex Data Translation: Converting high-fidelity sensor metrics into an intuitive "Z-Score" and actionable clinical insights for the user.
The Solution
Leenspace engineered a robust, cross-platform Flutter application that serves as the bridge between the user, the hardware, and Zerene’s professional coaching team.
Key technical milestones included:
- Reliable BLE Communication: We implemented a custom Bluetooth Low Energy (BLE) layer to ensure friction-free pairing and background data synchronization, preserving both phone and device battery life throughout the night.
- Three-Phase User Journey: The app was architected to guide users through distinct stages: Study Mode (baseline tracking), Training Mode (active biofeedback), and Maintenance Mode (habit reinforcement).
- Advanced Visualization: We built a custom dashboard that visualizes grinding intensity, bite frequency, and the proprietary Z-Score, allowing users to see their progress in real-time.
The Impact
The Zerene app successfully launched on iOS and Android, transforming a piece of hardware into a comprehensive digital therapeutic. By providing a stable link between the "Moon Module" and the cloud, we enabled:
- Clinical Efficacy: Early clinical data showed a +90% reduction in grinding intensity for many users within the first 21 days of training.
- Operational Excellence: 100% of sleep sessions are now securely and instantly synced to Zerene’s servers, allowing human coaches to provide personalized feedback based on accurate data.
- Scalable Architecture: A cloud-synced backend that supports Zerene’s growth from a startup to a leader in sleep-health technology.
