PingKit Cert Monitor showing TLS certificate expiry tracking for monitored domains PingKit Uptime Watch showing website availability monitoring with hourly HTTP probes

Five new superpowers.

Everything in Guardian, plus the tools that ops teams and security-conscious users have been asking for.

🔒

Cert Monitor

Add domains to your watch list and PingKit checks their TLS certificates every hour. Get a push notification at 30, 14, 7, and 1 day before a cert expires, or immediately if it fails validation. Never get caught by a surprise expiry again.

📄

ISO 27001 PDF Export

Generate a timestamped PDF certificate inventory covering issuer, subject, SANs, expiry, key size, signature algorithm, and TLS version for every monitored domain. Hand it to your auditor as evidence for ISO 27001:2022 control A.8.24 (Use of cryptography).

🧠

Network History AI

AI summarises your network activity over the past day, week, or month. See trends in latency, device churn, cert health, and uptime - explained in plain English instead of raw charts.

Apple Watch Complication

Glance at your wrist for real-time network status. The complication shows connection state, current latency, and alerts you with a tap when something needs attention.

Unlimited AI

No daily AI query cap. Ask the AI assistant as many questions as you need, generate unlimited security explanations, fix-it guides, scan summaries, and device classifications.

Questions & answers.

How does Cert Monitor work?

Add any domain to your watch list. PingKit connects over TLS once every hour and checks the certificate chain, expiration date, and signature algorithm. You get a push notification on your iPhone and Apple Watch at 30, 14, 7, and 1 day before expiry, or immediately if validation fails.

What does Uptime Watch actually monitor?

Uptime Watch sends HTTPS health checks to your endpoints at regular intervals. It records response codes, response time, and calculates an availability percentage. When an endpoint returns a non-2xx status or fails to respond, you get a push notification (reliably when the Mac Agent is running, best-effort from iPhone in the background). Your monitored targets and their results are stored on PingKit's backend to drive those alerts; the rest of your data stays on-device and syncs via your private iCloud.

How does the ISO 27001 PDF help with audits?

The PDF generates a timestamped certificate inventory for every domain you monitor: issuer, subject, SANs, expiry date, key size, signature algorithm, and TLS version. This provides evidence for ISO 27001:2022 control A.8.24 (Use of cryptography) and for certificate lifecycle management. Export it any time and share it directly from your iPhone.

Where is my Cert Monitor and Uptime Watch data stored?

Your monitored domains and their latest certificate and uptime results are stored on PingKit's own backend (a Cloudflare Worker) so alerts and push notifications reach you reliably, even while your devices are asleep. That backend holds only the domains you choose to monitor and their check results, nothing else, and it is never sold or shared. All of your other data (device inventory, scans, and diagnostics) stays on your device and syncs only through your private iCloud. See our Privacy Policy for the full breakdown.

What is the difference between Guardian and Guardian Plus?

Guardian ($2.99/mo) includes AI chat, security explanations, Mac Agent monitoring, Uptime Watch, smart alerts, and iCloud sync. Guardian Plus ($4.99/mo) adds Cert Monitor for up to 25 domains, ISO 27001 compliance PDF export, Network History AI summaries, an Apple Watch complication, and unlimited AI queries with no daily cap.

Can I try Guardian Plus before subscribing?

Yes. Guardian Plus includes a 1-week free trial. Set up Cert Monitor, configure Uptime Watch, and explore every feature. Cancel any time during the trial and you will not be charged.
