About Calotick
Calotick is a calendar and clock app designed to repurpose old smartphones and tablets as always-on smart displays.
Repurpose Your Old Devices
Many households have old smartphones or tablets gathering dust — devices with cracked screens or degraded batteries that are no longer suitable for calls or heavy app use, but still perfectly capable of displaying information over Wi-Fi.
Calotick addresses this by turning these devices into always-on smart displays. Simply plug in your device and place it on your desk, bedside table, or kitchen counter. No special hardware purchase required — just use what you already have.
Because Calotick is built for continuous display, it includes thoughtful features to prevent screen burn-in. Our mission is to bring the concept of digital signage into everyday personal life, making information access seamless and effortless.
Key Features
Burn-In Protection
Slowly shifts display content to prevent burn-in on OLED and LCD panels, enabling safe long-term always-on use.
Wake Lock Support
Uses the Screen Wake Lock API to prevent device sleep. Just plug in and leave — your display stays on showing the latest time and calendar.
Google Calendar Integration
Displays Google Calendar events in real time. Use it as a smart display to check meetings and reminders at a glance.
Multi-Device Support
Works on any device with a browser — Android, iPhone, iPad, PC. Install as a PWA for an app-like experience.
Development
Calotick is an open project built by an independent developer, aiming to contribute to reducing electronic waste while making information display more accessible.
