Description
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.
