CertWatch

SSL certificate expiry tracker

Free · In‑App Purchases · Designed for iPad. Not verified for macOS.

Monitor TLS certificate expiry before it becomes an outage. Add a hostname, inspect the live chain, and get local alerts — all on your device, no account required. CertWatch is a local-first SSL/TLS certificate expiry tracker for iOS. Add the domains and hostnames you care about, inspect their live certificates, and get notified before they expire — without signing up for a service or sending your data to a backend. Built for developers, sysadmins, and anyone responsible for keeping sites online. WHY CERTWATCH? Certificate expiry is one of the most avoidable causes of downtime. CertWatch gives you a clear, focused view of when certificates expire across the endpoints you monitor — directly from your iPhone or iPad. No accounts. No cloud sync. No tracking. Your monitored endpoints and certificate data stay on your device. FREE FEATURES • Monitor up to 5 endpoints • Live TLS certificate inspection for any hostname or IP you enter • Expiry dashboard with colour-coded status badges and validity progress • Certificate detail view with subject, issuer, SANs, serial number, and full chain • Copy or share certificate PEM data • Manual refresh for individual endpoints or your entire list • Local expiry notification 30 days before a certificate expires • Clean, dark developer-focused interface CERTWATCH PRO (ONE-TIME PURCHASE) Upgrade once to unlock: • Unlimited endpoints • Custom notification thresholds (e.g. 30, 14, 7, and 1 day before expiry) • Home Screen widgets — small and medium sizes showing your soonest expiring certificates • Daily background refresh to keep certificate data up to date • Tags and notes for organising endpoints • Export and import your endpoint list as JSON HOW IT WORKS 1. Add a hostname or URL (e.g. api.example.com or https://example.com:8443) 2. CertWatch connects over TLS and reads the presented certificate chain 3. View expiry dates, issuer details, and certificate metadata 4. Get local alerts before certificates expire CertWatch only connects to hostnames you explicitly add. It does not scan your network or monitor anything in the background without your action.
