Everything in Guardian, plus the tools that ops teams and security-conscious users have been asking for.
Add domains to your watch list and PingKit checks their TLS certificates on a schedule. Get a push notification when a cert is expiring, misconfigured, or uses a weak cipher suite. Never get caught by a surprise expiry again.
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 Annex A.12 cryptographic controls.
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.
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.
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.
All 19 tools are free. Pick the monitoring level that fits your needs.

Add any domain to your watch list. PingKit connects over TLS on a schedule you choose (hourly, every 6 hours, or daily) and checks the certificate chain, expiration date, and cipher suite. When a certificate is within your configured expiry threshold or fails validation, you get a push notification on your iPhone and Apple Watch.
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 an immediate notification. All data is stored on-device and synced via iCloud.
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 the evidence auditors need for ISO 27001 Annex A.12 (cryptographic controls) and certificate lifecycle management. Export it any time and share it directly from your iPhone.
No. All monitoring data stays on your devices and syncs through your personal iCloud account. PingKit never stores your domain list, certificate data, or uptime results on PingKit-operated servers. AI features send anonymous, ephemeral data for processing but nothing is retained.
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.
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.
