Website uptime
Scheduled HTTP(S) checks with your own expected status range, keyword rules and User-Agent. Response time and uptime history for 24h, 7d, 30d and 90d.
No account · No servers · Encrypted on device
Know the moment your site, API or certificate goes down.
Uptime Guard watches your websites, API endpoints, SSL certificates and domain expiry dates from your phone — and tells you the second something breaks, then again when it recovers.
Free · Android 8.0 and later · iOS coming soon

One app for everything that can quietly break
Uptime, APIs, certificates, domains, DNS and mail configuration — checked on a schedule, reported in plain language.
API monitoring
Import a Postman collection or paste a cURL command, fill in your variables, and every request is run on a schedule with per-request pass/fail, status codes and timings.
Auto-login for protected APIs
Mark one request as your login call; the returned token is captured and injected into the rest. Credentials and variables are stored encrypted on device.
SSL & domain expiry
Certificate validity is read straight from the host and registration data via public RDAP, with escalating reminders at 30, 14, 7 and 1 days so nothing lapses unnoticed.
Domain Health report
An MxToolbox-style report in one tap: DNS and SOA validation, MX, SPF, DMARC and DKIM, blacklist screening across five RBLs, plus web server and TLS reachability.
Alerts where you work
Local push notifications the moment a monitor goes down or recovers — and, if you want them, the same alerts forwarded to Slack, Discord, Telegram or any webhook.
Tools with zero setup
Test any URL on the spot, look up A, AAAA, CNAME, MX, TXT, NS and SOA records, or run a full health report — without saving anything to your monitors.
Real-time mode
Opt in on Android to a foreground service that re-checks every monitor every 1–5 minutes, for genuinely near-real-time alerts when you are mid-incident.
Private by architecture
There is no cloud to opt out of. Monitors, history and credentials live in an encrypted database on your device, optionally behind Face ID or a fingerprint.
A look inside
Built for people who get paged: dense where it matters, quiet the rest of the time.

Add what you care about
Enter a URL or domain, or import a Postman collection or cURL command for an API. Attach a logo if you like.
Define what “up” means
Pick the expected status range, an optional keyword that must appear in the response, and how often to check.
Get told when it breaks
Allow notifications and, optionally, point alerts at Slack, Discord, Telegram or a webhook. Then forget about it.
Privacy
Your monitoring data never reaches us
Uptime Guard has no backend. We could not read your monitors, credentials or history if we wanted to — there is nowhere for them to go.
Read the privacy policy- No account or sign-in — the app works the moment you open it.
- Local, encrypted storage — SQLCipher, with the key held in the Android Keystore or Apple Keychain.
- No analytics, ads, tracking or crash SDKs — none, at any tier.
- Only the connections you ask for — the sites you monitor, plus DNS and RDAP lookups when you run them.
- Optional app lock — Face ID, fingerprint or device PIN.
- Deleting is deleting — uninstalling removes the database and its key from the device.
Common questions
More answers, including troubleshooting, on the support page.
Do I need an account?
No. There is no sign-up, no login and no cloud backend. Everything lives on your device from the first launch.
Does it keep checking when the app is closed?
Yes, within the limits the operating system allows. Android uses WorkManager with a ~15-minute floor; iOS schedules opportunistic background tasks, so timing is decided by the system. The app always runs a catch-up check when you open it and shows an honest “last checked” timestamp. For near-real-time checks, Android has an opt-in Real-time mode. Guaranteed 24/7 checks with the app closed would require a server — which is exactly what Uptime Guard does not have.
Can I forward alerts to my team?
Yes — Slack, Discord, Telegram or any custom webhook. Alerts contain the monitor name, the affected host and the event, and nothing else.
Is it really free?
Yes. There is no subscription, no per-monitor pricing and no ads. Because there is no infrastructure behind it, there is nothing to bill for.
Is there an iOS version?
The app is built for both platforms and the iOS release is on its way. Android is available on Google Play today.
