Radien - looking for VoiceOver feedback on my network diagnostics application

By Igor Arsenkin, 28 July, 2026

iOS and iPadOS
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.
I put a lot of effort into making it fully accessible. I'd be grateful if members of the AppleVis community could try it and let me know about any accessibility issues or suggestions for improvement.

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 for your time, and I look forward to hearing your feedback.
Igor

Hi,

Thanks for posting this, it’s always nice to see a developer taking interest in accessibility and it’s clear how much thought you have put into this already.

I’d love to test this out if you’d be able to provide a code?

By Igor Arsenkin on Tuesday, July 28, 2026 - 21:09

Hi!
I just sent you the promo code in a direct message. Happy testing, and thank you for offering!

The same goes for anyone else reading: if the price is a barrier and you would like to test Radien with VoiceOver, just ask and I will send you a code.

This sounds like a great app, an I love that you've leveraged the audio graphs feature, which is not widely used outside Apple's own ecosystem.
I'm looking forward to giving it a spin!

Thank you for the kind words! Audio Graphs were my favourite part to build, and you are right that almost nobody outside Apple uses them.

On the Ping screen, focus the chart, twist two fingers until you reach Audio Graph in the rotor, then swipe up. You will hear the latency as tones, with gaps where a packet timed out. I would love to know how it sounds to you in real use.

Hi everyone,

Radien 1.7 is out today. It is a small polish update, but it includes two useful changes for VoiceOver:

Network Details now hides rows that your current connection cannot answer, so there are fewer empty rows to swipe past.

On cellular connections, the details sheet now includes two new spoken rows: radio technology and the NAT64 prefix.

Callum, did you get a chance to test the app with the code I sent you? Mlth, did you have a chance to try the Audio Graphs feature? I would still be very grateful for any reports, especially from people who use a Braille display.

Radien itself is free. I still have codes that unlock Radien Pro, for anyone who would like to test it with VoiceOver. The current batch is valid until 31 December. You can contact me through the AppleVis personal contact form, or leave a comment here, and I will send you a redemption link.

Also, if a community member feels Radien is suitable for the AppleVis App Directory, I would really appreciate an honest entry. The AppleVis guidelines do not allow developers to submit their own apps, so it can only happen through a community member. Please include anything that does not work well too - honest feedback is the most useful kind.

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!
Igor

Thanks for adding VoiceOver support to your app. This sounds like something I'd find useful and I'm definitely going to check it out. I'd love a promo code if you have any remaining, but I'll be back with my feedback regardless.

Hi!
I just sent you a redemption link through the AppleVis contact form - it should arrive by email. Radien itself is free; the link unlocks Radien Pro.

Thank you for giving it a try. I am looking forward to your feedback, good or bad - and if the link does not arrive or something goes wrong with the redemption, leave a comment here and I will resend it.

Just spent some time playing with the app, and I think it works very well with VoiceOver. A lot of developers ignore the VoiceOver rotor, so it's cool to see it used here.
I particularly like the preset destinations, such as the user's router for the ping command, and the intentionally expired SSL certificate test.
Thanks for the work you've done here. I don't have anything negative to say. This will certainly come in handy and has replaced an older app called Network Tools that I used to use.

By Igor Arsenkin on Wednesday, August 19, 2026 - 06:22

Thank you - this comment made my day. Replacing an app you already used is the biggest compliment a developer can get.
The rotor work was a deliberate goal of the accessibility pass: nothing in Radien should require a long press. I am glad the Router preset and the expired-certificate targets landed too. The badssl targets are there because an honest tool should also show you what a bad result looks like, safely.
If anything ever reads wrong with VoiceOver in a future update, please tell me here and I will fix it. Thank you again for testing!

I was wondering if I could get a code for this app. I will be glad to submit feedback. Thanks.
