About this app
Nightbell is a serverless uptime monitoring application designed specifically for Android devices. It allows you to monitor websites, HTTP endpoints, web page elements, or GitHub repositories directly from your phone without requiring any third-party accounts or external servers. Checks are executed locally, and when an outage is detected, Nightbell bypasses standard dismissible notifications by triggering a full-screen alert paired with a looping, persistent alarm to ensure you actually wake up and notice the downtime.
