SentryPing keeps an eye on your websites, APIs, and servers — and tells you the moment something goes down, right from your pocket. Add an endpoint, and SentryPing checks it in the background and alerts you on outages and recoveries. Everything runs on-device: no account, no sign-up, no tracking. MONITOR ANYTHING • Watch any URL or host — websites, REST APIs, health checks, home servers • Set expected status codes, a latency ceiling, check interval, and a failure threshold to avoid false alarms • See status at a glance: Up, Degraded, or Down GLANCEABLE, EVERYWHERE • Home Screen widgets with your status summary and top monitors • Lock Screen widgets — circular, rectangular, and inline • Live Activity + Dynamic Island: watch an outage's downtime tick up in real time • A "Check Now" control for the Lock Screen and Control Center — also available in Shortcuts and Siri SMART ALERTS • Get notified when a monitor goes down, and again when it recovers • Debounced so a single blip won't spam you ON YOUR WRIST • A SentryPing app for Apple Watch — your status summary and every monitor at a glance • Kept up to date by your iPhone automatically FIND DEVICES • Find the devices on the network you're connected to — router, NAS, printer, home server • See each device's address and which common ports answered, then add it as a monitor in a tap • Everything happens on your device; nothing about your network leaves it QUICK PING • One-tap "ping ×3" to any URL over HTTP, or any device on your network over ICMP — even a router, NAS, or printer with no web server • See per-request latency plus a min / avg / max summary — like ping, in your pocket HISTORY & INSIGHT • Latency sparkline, uptime %, recent checks, and an incident log for every monitor PRIVATE BY DESIGN • Fully on-device. Your endpoints and tokens never leave your iPhone. Note: background checks are best-effort — iOS decides when apps may run in the background.
