VÖRDNET is a lightweight monitoring app for checking the status of your services, domains, and network from your iPhone. Configure monitors to check URLs, DNS, TCP ports, TLS certificates, your public IP address, latency, and possible captive portals. VordNet stores recent results, displays status information in widgets, and can alert you when it detects important changes. Designed for users who want to know whether their services are still responding without relying on complex tools. Main features: • HTTP monitors to check whether a URL responds. • DNS monitors to validate domain name resolution. • TCP port monitors to check whether a host accepts connections on a port. • TLS certificate monitors to validate HTTPS connections. • Public IP monitor to display the IP address detected from the internet. • Detection of possible captive portals on the current network. • Latency monitor to measure approximate response times. • Widgets for viewing recent status information from the Home Screen. • Alerts when a monitor’s status changes. • Privacy mode for hiding sensitive information. • Network tools such as Ping and Subnet Ping. VÖRDNET is designed for practical monitoring, quick checks, and basic diagnostics. Widgets display the latest result saved by the app; they do not perform tests on their own. Use it to check personal services, websites, APIs, domains, network devices, important ports, or connections you want to monitor from your iPhone. VÖRDNET lets you configure up to 3 monitors.
