Radien - looking for VoiceOver feedback on my network diagnostics application

Hi! I am an independent developer with more than 10 years of experience writing production code for big companies. I have just finished my own app, Radien, a network diagnostics toolbox for iPhone and iPad running iOS 18 or later, which also runs on Apple Silicon Macs. I have just released an update that makes it fully usable with VoiceOver, including Audio Graphs on the latency chart, so ping results can be heard as tones. Here is the link to the app on the App Store: Radien: Network Toolbox I built it exclusively with Apple frameworks: no third-party SDKs, no ads, no trackers, no analytics, no accounts and no servers. Nothing leaves the device except the connections the user asks for.

What is on the screen

The first screen is a catalog of the tools, with a live network status card at the top that shows your connection type, your local IP address and your router's address. Activating that card opens a details sheet with more, such as your public IP address and DNS servers. Below it the tools are grouped into three sections. Diagnostics holds Ping, Multi Ping, Traceroute, Port Scanner and TLS Inspector. DNS holds DNS Lookup and Reverse DNS. Calculators holds the Subnet Calculator, IP Converter and MAC Converter. Every tool screen follows the same shape: a host field at the top, a Start or Stop button to the right of it, then the list of results, and a verdict card in plain language at the end of a run.

What every tool does

• Ping - latency, jitter and packet loss to any host, with a live chart and a plain-language verdict.
• Multi Ping - compare up to four hosts side by side, at once.
• Traceroute - every hop between you and a destination, with reverse-DNS names and an honest read on where delay or loss begins.
• DNS Lookup & Reverse DNS - query A, AAAA, MX, TXT, NS and more against the system resolver or Google, Cloudflare and Quad9. Enter an IP for a reverse PTR lookup.
• Port Scanner - see which TCP ports are open, closed or filtered, over an honest model, never a fake vulnerability claim.
• TLS Inspector - read a site's real certificate chain, protocol versions and cipher support, straight from your device. No third-party grading service.
• Subnet Calculator - IPv4 and IPv6 math: CIDR, network, broadcast, host ranges and equal splits, with a live bit view.
• IP Converter - turn any IP notation into every other form, and see how an IPv4 address rides inside IPv6.
• MAC Converter - every MAC notation, EUI-64, link-local, and a fully offline vendor lookup. Randomized phone MACs are flagged honestly, never given a fake vendor.

The VoiceOver work

• Every long-press action is available as a rotor custom action, so nothing requires a long press.
• Result rows are grouped, so a hop or a port reads as one sentence.
• The ping chart supports Audio Graphs. Focus the chart, twist two fingers on the screen until you reach Audio Graph in the rotor, then swipe up to play it.
• "Started" and "Finished" are announced, and on Ping the finish also speaks the verdict.
• Controls that need the paid unlock announce that before you activate them.
• Decorative visualizations are deliberately hidden, because the result rows already speak everything they show.
• Larger Text, Reduce Motion and Voice Control are all supported as well.

Feedback

I would like to know how Radien behaves in real use: starting and stopping the tools, the announcements, the results and the verdict cards, and whether anything is confusing, too noisy or missing. I am especially interested in feedback from Braille display users, because unfortunately I have no Braille hardware and could not test that myself. If someone in the community would be willing to review Radien and add it to the AppleVis Directory, I would be very grateful. Radien is localized into English, Chinese, German, French, Italian, Japanese, Korean, Portuguese and Spanish, including all VoiceOver labels, hints and announcements. If you use any of these languages, I would really appreciate your feedback on how accurate and natural the VoiceOver translations sound.

Price and promo codes

Radien is free, with a one-time Radien Pro unlock for $9.99. There is no subscription. If you would like to test Radien but the price is a problem, I would be happy to provide a few promo codes in exchange for accessibility feedback. You can contact me through the AppleVis personal contact form, or leave a comment asking for a code. English is not my first language, so I used an AI tool to help with the wording. The app, the testing and any mistakes are my own. Thank you, and I look forward to hearing from you. Igor
