About this app

■ Is your site loading fine right now?
Site Internet Speed Monitor (NetWatch) automatically monitors the response speed of the websites and servers you run or use often. If your site slows down or goes
offline, it notifies you right away with a push notification — no need to keep refreshing to check.

■ Key features
▷ Automatic status monitoring
Just register a site address, and it automatically checks the connection at the interval you set (10 min, 30 min, 1 hour, 3 hours, or a custom value). The server
does the checking for you even when the app isn't open.

▷ Instant push notifications
Get notified when your site goes down, when it slows down, and when it recovers. Each notification type can be turned on or off per site.

▷ Response speed graph
View response speed over time in a graph to see at a glance when your site slows down. Outage history is recorded for each site as well.

▷ Multiple check methods
Combine HTTP response, Ping, and TCP port checks however you like. Beyond websites, you can monitor game servers, mail servers, or anything with an open port.

▷ Measure your phone's internet speed
Instantly measure the download speed and latency (ping) of your current Wi-Fi or mobile data. When the internet is slow, tell whether it's your connection or the site.

▷ Adjust the sensitivity yourself
Decide "how many seconds counts as slow" and "how many consecutive failures before an alert" yourself, so you're never bothered by unnecessary notifications.

■ Recommended for

· People who want to find the cause when the internet is slow

■ Supported languages
Supports Korean, English, Japanese, Chinese, and Spanish, and follows your device language automatically.

What’s new

• SSL certificate expiry alerts: Get notified before your HTTPS site's certificate expires. See the expiry date and issuer right on the site screen.
• Slowdown & outage cause hints: When a site is slow or unreachable, we now estimate which stage (DNS, connection, server) is at fault.
• Clearer packet-loss labeling: Servers that block ping now show "Ping blocked" instead of a misleading "100% loss."
• Stability improvements and bug fixes.
