Project Development Progress
Hardware
The CloudBell Unit hardware is already 60% complete. The core electronic components and circuit board are fully functional, and the design of the enclosure is finalized. The next steps focus on refining durability, miniaturization, and ensuring stable performance in different environments.
Software
Our software development phase has reached 75%. The CloudBell App already handles real-time synchronization, smart alerts, and seamless integration with the Unit. Current efforts are centered on optimization, cloud stability, and preparing for multi-device management.
Testing
Testing is actively in progress, reaching about 40%. Prototype units are being tested in real school environments to ensure reliability and user safety. Each feedback cycle helps us refine both firmware and mobile app performance before the public release.
UI/UX Design
Our software development phase has reached 75%. The CloudBell App already handles real-time synchronization, smart alerts, and seamless integration with the Unit. Current efforts are centered on optimization, cloud stability, and preparing for multi-device management.
Countdown to Full Launch
CloudBell Development Timeline
Early 2025 — Building the Core Desktop App
The journey began with the creation of the CloudBell Desktop application, written in Python. It became the foundation of the entire system — managing bell sounds, schedules, and alerts directly from a PC. At this stage, the focus was on stability, fast response time, and cross-platform compatibility.
Spring 2025 — Expanding Features & Cloud Integration
New features were introduced, including multi-device synchronization, cloud control, event logging, and backup support. The app also gained a communication module for future integration with the physical CloudBell Unit, bridging digital and hardware layers of the system.
Autumn 2025 — The CloudBell Unit Prototype
The first physical prototype of the CloudBell Unit was developed and successfully tested. Built on Raspberry Pi Zero 2W with a custom Hi-Fi DAC expansion board, it transformed the software into a tangible, connected device — bringing clear, synchronized alerts to every classroom.
Winter 2025 — System Integration & Launch Preparation
All system components were unified under a single cloud environment — CloudBell App + Unit + Dashboard. Final tests, UI/UX refinements, and user feedback collection are paving the way for the full public release in 2026.
