NETWORK TOOLS

• Port Scanner: Instantly scan any host for open TCP ports. Grabs service banners, identifies running services, and can launch the right app for known protocols (SSH, Telnet, HTTP, HTTPS, FTP, SMB and more).
• Port Scanner Multi (Pro): Scan an entire IP range to discover every device and their open ports in one sweep.
• Local Network Scanner: See every device on your network. Identifies device vendors from MAC addresses so you always know what's connected.
• WiFi Analyzer: Scan nearby networks, analyse signal strength, and browse channels across 2.4 GHz, 5 GHz, and 6 GHz bands. Find the quietest channel for your router.
• Speed Test: Measure your real download speed, upload speed, ping, and jitter. Track results over time to spot trends.
• Ping: Test reachability and latency with ICMP, TCP, or HTTP ping. View min/max/average stats and packet loss.
• Ping Graph (Pro): Visualise ping latency over time with a live graph. Great for spotting intermittent drops.
• Traceroute: Map the path your traffic takes across the internet, with geo-location and map visualisation of each hop.
• mDNS Browser: Discover Bonjour/mDNS services on your local network, including printers, media servers, and smart home devices.
• UPnP Browser: Find UPnP devices on your network using SSDP discovery.

SECURITY AND DIAGNOSTICS

• Certificate Viewer: Inspect SSL/TLS certificates for any host. Check validity, expiry dates, issuer chain, and subject alternative names.
• DNS Lookup: Query any DNS record type (A, AAAA, MX, TXT, CNAME and more) with exhaustive lookup support.
• Reverse IP Lookup: Find all domains hosted on a given IP address.
• WHOIS Lookup: Look up registration details, registrar, nameservers, and expiry for any domain.
• IP Calculator: Calculate subnet masks, network addresses, host ranges, and broadcast addresses from any IP and CIDR prefix.
• Device Info: View your device's full network configuration including IPs, MAC addresses, and connection details.
• Wake-On-LAN: Wake compatible devices on your network by sending a magic packet to their MAC address.

Ratings and reviews

I don't know much but as an average user of home networking...I like the application and the features ..some adjustments and I think this application will be very useful...Ports usage and protocol is excellent and a programmer is able to have a better understanding of common ports and protocol use...I gave it a three star because some minor glitches and the pinging of certains ports weren't working well. As a member of beginnings of the digital age these are some things I noticed.

Why use anything else? This app does everything I could want. I even made a feature request for mDNS and the developer responded within minutes, and released the feature within a day! Absolutely incredible! The pro features are reasonable in that they're purely nice-to-haves. The free version does everything you'd need but the pro features are great add-ons and worth it. I did the lifetime purchase and couldn't be more pleased. One of the best made apps I've used. Bravo!

Overall a great app, while a bit lacking upon first use, it's improved dramatically over a past few months. I'm thoroughly surprised at the maintainer's commitment to engaging with users and doing their best to implement the features requested. At this rate, it'll will likely become one of the more notable apps on the market.
