Network Radar vs ContactKeeper

Whether for troubleshooting, security, or simple curiosity, it’s always helpful to know which devices are connected to your network. Network Radar is a powerful yet easy-to-use network scanning and management tool for iPhone and iPad that gives you detailed insights into all devices on your network. As Network Radar scans, it instantly displays newly discovered devices. For each device, you can view comprehensive information such as IP address, DNS names, mDNS name, open ports, response time, and more. You can also create scans with custom IP ranges. All scans are saved and can be revisited later — even when your device is no longer connected to that network. Take advantage of the built-in network utilities, including Ping, Port Scan, Whois, and DNS lookups (forward and reverse). These tools work not only within your local network but also with external IP addresses and domains. Network Radar is not limited to your local network. Specify custom start and end addresses to scan any reachable segment of any network from your device. With its intuitive user interface, Network Radar is simple to use across all your iOS devices. It’s a modern, efficient app designed for iOS with minimal impact on your network. By the way, Network Radar is also available for macOS — check it out!
