Android app to check TLS cert expiry, TCP ports and HTTP endpoints Latency/Status

Posted by Dependent_Stretch_25@reddit | sysadmin | View on Reddit | 1 comments

Tired of getting surprised by expired TLS certs or services going down, I built OpsMon as a solo developer — an Android app that monitors your infrastructure directly from your phone.

What it checks:

TLS/HTTPS certificate details and expiry
TCP port availability
HTTP endpoint status (non-2xx detection)
Latency with phase breakdown: DNS / TCP / TLS / TTFB

Things to know:

Free app, no account required.
No agent on server. Everything runs on-device.
Ads via Google AdMob (banner).
Built with AI-assisted design/development — no AI at runtime.

Google Play Store link here for OpsMon (or check this user guide for screenshots and details. )

Happy to take feedback for future improvement.
