SentryPingUptime monitoring
in your pocket.
SentryPing watches your websites, APIs, and servers — and tells you the moment something goes down, right on your Lock Screen.
Everything you need to stay ahead of downtime
A focused, native iOS monitor — not a bloated dashboard bolted onto an app.
Monitor anything
Any URL or host — websites, REST APIs, health checks, home servers. Set expected status codes, a latency ceiling, and a failure threshold to avoid false alarms.
Smart alerts
Get notified when a monitor goes down, and again when it recovers. Debounced so a single blip won't spam you.
Live Activity & widgets
Watch an outage's downtime tick up in the Dynamic Island. Home Screen and Lock Screen widgets show status at a glance.
Quick Ping
One-tap “ping ×3” to any URL over HTTP — or any device on your network over ICMP, even one with no web server. See min / avg / max latency.
History & insight
Latency sparkline, uptime %, recent checks, and an incident log for every monitor.
Private by design
Fully on-device. No account, no sign-up, no tracking. Your endpoints and tokens never leave your iPhone.
