Site Monitor - Uptime Tracker

Downtime Alerts & Status Check

$1.99

New: iCloud sync for your monitor list. Turn a spare iPhone, iPad, or Mac into an uptime monitor with response time, downtime, and status graphs. No server needed. Is your website or API actually online right now? Turn a spare iPhone, iPad, or Mac into a dedicated uptime monitor that checks for you — 24/7, with no server and no account. ■ How It Works Site Monitor sends periodic GET requests to the websites and APIs you choose, then records response time, HTTP status, and success or failure for every single check. All monitoring, recording, and charting happens right on your device — nothing is sent to us, and there's no subscription to manage. ■ Key Features · Uptime monitoring for any URL via periodic GET requests · Response time recording, down to the millisecond · HTTP status code recording, checked against your expected status · Timeout detection · Automatic uptime percentage and downtime calculation · Average, fastest, and slowest response time · Automatic incident detection when a site goes down, and when it recovers · Response time graphs (1 hour, 24 hours, 7 days, or 30 days) · History screen with per-site and per-status (success / failed / timeout) filters · Add, edit, delete, and enable/disable monitors anytime · Configurable check interval, timeout, and expected HTTP status code · Local notifications the moment a site goes down, and when it's back · Prevents your device from auto-locking while monitoring runs · CSV export of logs, ready to share or save · Log retention settings (7, 30, or 90 days, or forever) with automatic cleanup · Optional iCloud sync — share your monitor list across your other devices · Light, Dark, and System appearance · Available in Japanese and English · Native UI tailored to iPhone, iPad, and Mac ■ Who It's For · Independent developers who want uptime monitoring without a monthly subscription · Anyone running a personal site, blog, or small API who wants peace of mind · Solo operators and small teams keeping an eye on a service without enterprise tooling · Anyone with a spare iPhone or iPad looking for a genuinely useful second life for it ■ Why Site Monitor · No server, no account, no subscription — everything runs in the app itself · 100% free, with every feature listed above included · All check history is stored only on your device · A real native UI for each platform — iPhone, iPad, and Mac all feel right at home ■ Privacy The results of checking your monitored URLs (response time, status codes, and so on) are stored entirely on your device. Other than contacting the URLs you specify for monitoring, the app never sends your data to an external server. If you turn on iCloud sync, only your monitor settings (names and URLs) are synced to your own iCloud account — check history always stays on-device. Stop wondering if your site is still up. Download Site Monitor and put a spare device to work watching it for you.
