SSL Certificate Monitor

Track SSL certificate expiry with smart alerts and widgets

SSL Certificate Monitor is a focused, no-nonsense tool designed for admins, developers and site owners who can’t afford an expired certificate surprise. Rather than trying to do everything, it concentrates on one critical job: tracking the validity of your web SSL certificates and warning you before they become a problem.

The core experience is built around organizing certificates into folders, which works well if you manage multiple sites or environments (for example, separating staging, production and client projects). Adding hosts is straightforward, and once configured, the app quietly polls their certificates in the background, keeping an eye on expiry dates and changes.

Notifications are a standout feature. Instead of cryptic messages, SSL Certificate Monitor sends clear, concise push alerts summarizing which certificates are close to expiry, so you know exactly where to focus. The optional home screen widget is equally useful, giving you an at-a-glance view of upcoming expirations without having to open the app.

A thoughtful extra is the built-in backup of all settings. If you switch devices or need to restore your configuration, you can bring back your folders and hosts instead of starting from scratch.

On the downside, the free tier is limited to one folder with a single certificate host, which might feel restrictive for users managing several domains. It also only tracks web certificates, not those used for FTP or mail servers, so it won’t cover every possible use case.

Despite these limits, SSL Certificate Monitor excels at what it promises: dependable, organized monitoring of web SSL certificates with timely alerts that help prevent costly downtime and security warnings.
