SSL Quick Check

Never get caught out by an expired certificate again. Track your sites' SSL/TLS certificates on-device, with early expiry reminders. Free & unlimited.

SSL Quick Check keeps an eye on your websites' SSL/TLS certificates so you're never caught out by an expired certificate again.

Add the domains you care about and the app checks each certificate right on your device — no account, no server, no data collection.

WHAT YOU GET • Expiry at a glance — see how many days are left, sorted so the soonest-to-expire are on top. • Early reminders — get a notification a month, a week and a day before a certificate expires. Expired or broken certificates always alert you. • Full certificate details — issuer, validity dates, SAN, TLS protocol, cipher suite, signature algorithm, key, serial number, chain length and hostname match. • Problem detection — instantly spot expired, untrusted or hostname-mismatched certificates. • Tags & grouping — organise sites with tags and group the list by tag, with a colour-coded status for each group. • Search — filter by name or domain. • Free and unlimited — track as many sites as you want.

PRIVATE BY DESIGN Everything runs on your device. The app only connects to the domains you add, purely to read their public certificate. It collects no personal data, shows no ads, and contains no trackers.

Perfect for developers, sysadmins, agencies and anyone who runs websites and wants a simple, reliable way to stay ahead of certificate expiry.
