UptimeOwl
Free Uptime Monitor for Android
Monitor your websites, APIs, and services from your phone. Get push notifications when something goes down, track response times with graphs, and keep a full check history. No account, no cloud — everything runs on your device.
Features
Monitor Dashboard
See all your endpoints at a glance — green for up, red for down, yellow for checking. Response time and uptime percentage on every card.
Push Notifications
Get notified instantly when an endpoint goes down or comes back up. Never miss an outage again.
Response Time Graphs
Custom-drawn line graphs show response time trends. Green lines for success, red dots for failures.
Flexible Intervals
Check every 1, 5, 15, 30, or 60 minutes. Each monitor has its own independent schedule.
HTTP & HEAD Checks
Support for GET and HEAD methods. Configure expected status codes (200, 301, etc.) per monitor.
Check History
Full history of every check — status code, response time, errors. See exactly when and why things went wrong.
Background Workers
WorkManager-powered background checks that survive app restarts and device reboots.
Dark Theme
Beautiful Catppuccin Mocha dark theme. Easy on the eyes for checking your monitors at any hour.
Privacy First
No cloud, no account, no telemetry. All monitor data stays on your device. Your endpoints are your business.
