Radien - looking for VoiceOver feedback on my network diagnostics application

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.

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

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.

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!

Thank you, WhappleMcFootenball, for adding Radien to the App Directory!
"Fully accessible with VoiceOver and easy to navigate" is the sentence I worked hardest for, and reading it from a real user means a lot. If a future update ever falls short of it, tell me here and I will fix it.

Hi!

The redemption link is on its way - I sent it a moment ago through the AppleVis contact form, so please check your email. A quick reminder: Radien itself is free to download, and the link unlocks the paid Radien Pro features.

Thank you for offering to test! If the email does not show up, just write here and I will send you a new link.

Hi!
Yes - plenty of codes left. I just sent you a redemption link through the AppleVis contact form, so please check your email. Radien is free to download; the link unlocks Radien Pro. If nothing arrives, write here and I will resend it.

"I've been looking for something like this" is exactly what I hoped someone would say - I would love to hear how it works for you.

Thank you - and perfect timing indeed!

For a freshly upgraded network, two fun first stops: Ping with the Router quick target, and the Subnet Calculator - it opens already filled in with your own network's numbers.

If anything ever reads wrong with VoiceOver, tell me here and I will fix it.

Enjoy the new connection!

Thank you!
The info buttons were built exactly for that - a short reference that lives in the app and sticks to what matters. I am really glad they read well.

And a Braille display test would mean a lot: it is the one part of the accessibility work I could never test myself, since I have no Braille hardware. Whatever you find - smooth or broken - I want to hear all of it.

Hello again, and an update on this one.

Something in my first post was wrong

I listed Larger Text among the things Radien supported. That was true at the ordinary text sizes and not true at the accessibility ones. When I went through the app at the largest setting, screen by screen, I found host fields shorter than the text they were holding, values cut to a few characters, a status card that lost the end of every line, and one sheet whose whole column collapsed to about a quarter of the screen width. Calling that supported was wrong, and version 1.10 is the fix.

What changed

At the accessibility text sizes every screen now changes its shape instead of shrinking or cutting text: fields grow to fit their font, values sit under their titles, and nothing is squeezed into a narrow column. I went through the app screen by screen at the largest setting on the smallest iPhone, in all nine languages.

What this release does not change

This is a Dynamic Type release, not a VoiceOver release. I did not add VoiceOver features and I do not want to suggest otherwise. What I did was go back through the app with VoiceOver on to check that nothing regressed: the status card still reads as one element, every long-press action is still available as a rotor action, and the decorative visualizations are still kept out of the swipe order.

Testers are very welcome

If you use the larger accessibility sizes, I would like to know whether anything is still cut off, overlapping or simply awkward, and on which screen. Feedback in the other languages is just as useful: the layouts are hardest in German and Japanese, and I cannot judge how natural the wording sounds in them.

Radien is free, and the advanced tools are a one-time unlock. I am happy to give that unlock away to anyone here who wants to try the whole app: just ask in a comment below, and I will send you a redemption link privately, through your AppleVis contact form or mine. It is not a trial. The unlock is permanent and stays with your Apple ID, restorable on any device, exactly as if it had been bought.

Radien was added to the Directory in August by WhappleMcFootenball, which I appreciated more than I said at the time.

Radien: Network Toolbox

Hello again. Radien 2.0 is out today, and this time most of the news is for VoiceOver.

What VoiceOver got wrong, and is now fixed

In September a full review of the app's code found places where VoiceOver was not told the truth about the screen. I had missed every one of them:

• The Port Scanner's start screen read each port set as plain text. It never said "button", never said which set was chosen, and never said that a set needs Radien Pro. The Pin, Unpin and Remove actions sat on items VoiceOver could not reach.
• Network Details announced its values as buttons that did nothing, and its Copy action sat on a row VoiceOver never focused.
• The Radien Pro teaser in the TLS Inspector opened a screen when activated, but it read as two lines of plain text.
• The record type switches in the DNS Lookup options had no names at all.
• After a language change in Settings, a tool screen that stayed open kept the spoken names of its icon-only buttons in the old language.

All of these are fixed in 2.0.

What is new

• Radien Checkup, new in Radien Pro, checks your Wi-Fi, router, internet, DNS and website access in one run. With VoiceOver on, you hear "Checkup started", then each result as soon as it is known, one after another, for example "Router, passed. Your router answered, 4 milliseconds". You do not need to move around the screen while it runs, and when it ends, VoiceOver moves to the result.
• Every Options sheet now opens for free users too. A value that needs Radien Pro is not hidden: it says "Requires Radien Pro", and so do the alternate app icons.
• A new Home, with tabs for Home, Tools and Settings, and a free "What is my IP?" screen with your public IPv4 and IPv6 addresses.

Before the release I went through the new screens with VoiceOver: Home, the Checkup with its details page and Share menu, "What is my IP?", the Tools tab and the Radien Pro screen.

Testers are very welcome

I would most like to hear about the Checkup: is the pace of the spoken results comfortable, is anything said twice, and is the result easy to find when the run ends? If you use a Braille display, I would like to know how it reads there too.

The offer still stands. Radien is free, and I am happy to give the Radien Pro unlock, the Checkup included, to anyone here who wants to try the whole app: just ask in a comment below, and I will send you a redemption link privately, through your AppleVis contact form or mine. The unlock is permanent and stays with your Apple ID.

Radien: Network Toolbox

Hi Enes,

Not too late at all, and not disrespectful either: the offer is still open. I just sent you a redemption link through the AppleVis contact form, so please check your email. Radien is free to download, and the link unlocks Radien Pro for good, the Checkup included.

For a slow Wi-Fi connection, I would start with the Checkup on the Home tab. It tests your Wi-Fi, router, internet, DNS and websites in one run, and VoiceOver speaks each result as it comes in. For a longer look, open Multi Ping and ping your router (the Router button) and a public address such as 1.1.1.1 side by side. If your router's replies are already slow or lost, the trouble is between your iPhone and the router, usually the Wi-Fi itself. If the router answers fast and only the internet side is slow, the problem is further out, often at your provider.

One honest limit: Radien does not run speed tests, and iOS does not let apps read the Wi-Fi signal strength. So it shows where the delay starts, not how fast your line is.

If the email does not arrive, write here and I will resend the link. I would love to hear how the spoken Checkup results work for you.

Hi Enes,

Thank you for testing, and for such careful notes. Here are my answers, one by one.

The device model: "iPhone17,5" is Apple's internal model code for the iPhone 16e, and "iPhone14,6" really is the code of your SE (3rd generation). So, sorry, no iPhone was made just for you 😉. iOS gives apps this code, not the model's name, which is why many apps show it. Radien shows it at the bottom of Settings only to help with support, but you're right that it reads like a mistake, and I'll change it.

"Languages": you're right again. The row sets one language, so it should say "Language". I'll fix that too. Turkish is not one of Radien's nine languages yet. I've noted your request, and requests like yours help me decide which language comes next.

Home and Tools: a fair point. Home is meant as a quick look at your own network: its status, your public IP and the Checkup. Tools is the whole toolbox. The six tool shortcuts that version 2.0 added to Home repeat what the Tools tab already has, and I'm reviewing them now. Letting people pin their own favorite tools on Home is a good idea, and I've noted it.

The DNS result: the Checkup asked the DNS server that your Wi-Fi gives your iPhone (usually your router) to look up a name, and no answer came within 4 seconds. Please run the Checkup again later to see whether it happens every time. If it does and websites are slow to start loading, the router's DNS is likely part of your slow connection, and the suggestions on that result screen are the place to start. If websites open normally, your iPhone may get its names another way, for example through iCloud Private Relay, which does not use the router's DNS. You can also compare the two in DNS Lookup: look up the same name with System DNS, then with Cloudflare or Quad9. If the public server answers and System DNS does not, the router's DNS is the one to fix.

If you'd like me to look at your result, tap Share on the Checkup's result screen, choose Share Report, and send it to me through the AppleVis contact form or with Send Feedback in Radien's Settings. The report contains no IP addresses unless you choose Share with IP Addresses.

The Audio Graph: it is on Ping's latency chart. Open Ping (on the Home tab or in the Tools tab), choose a host, for example the Router button, and tap Start. Let it run for a minute, then tap Stop: the graph sounds best once the ping has stopped. Then double-tap the graph in the result card to open the full chart (VoiceOver reads the graph as "Latency, button"). Focus the chart, twist the rotor to Audio Graph, swipe up or down until you hear "Play Audio Graph", and double-tap. My first post left out that last double-tap, sorry.

Thanks again. I'd love to hear how Radien does with your Wi-Fi.

Hi Brian,

Not too late at all: the offer is still open. I just sent you a redemption link through the AppleVis contact form, so please check your email. Radien is free to download, and the link unlocks Radien Pro for good.

Since you studied networking with Cisco, here are a few things you may like to try.

Traceroute judges a path only by what reaches the destination, so a router that just rate-limits its own replies is not blamed for loss.

The Port Scanner tells open, closed and filtered apart, and it says when a probe never left the iPhone. It scans TCP only, with full connections: iOS gives apps no raw sockets, so there are no SYN or UDP scans.

DNS Lookup builds its own queries, so you can ask Google, Cloudflare or Quad9 directly and read SOA, SRV and CAA records.

The TLS Inspector lists the cipher suites a server accepts and the TLS versions it supports.

If you use VoiceOver, my reply to Enes above has the steps for hearing the latency chart as an Audio Graph.

I'd especially value your view as a network person: if a result claims more than the iPhone can see, or misses something you would expect, please tell me here.

Igor

Hi Brian,

Thank you for both reports. They are exactly what I hoped for, and they found a real bug.

Your network was fine; Radien was wrong. Defender's web protection works as a small VPN that stays on your iPhone and checks your DNS lookups (Microsoft calls it a local VPN). Radien recognizes a VPN only when all of your traffic goes through it, so it missed this one: that is why your first report says "VPN: Off". The Checkup then most likely sent its DNS question straight over Wi-Fi, to a DNS server that answers only through that VPN, and got nothing in 4 seconds, while the public server, also asked over Wi-Fi, answered in 33 ms. So "Your DNS server is not answering" was the Checkup's mistake, and your second run, with the VPN off, shows your network as it really is.

I'll fix this: Radien should notice a VPN like this one, say so in the report, and ask your DNS server the way your other apps do. You don't need to turn the VPN off for Radien in the meantime: only the Checkup keeps its checks on Wi-Fi, and the other tools follow your iPhone's usual route.

One question would help me reproduce it: which Defender feature uses the VPN on your iPhone, web protection or privacy protection?

And a small tip: Share Report already leaves out your IP addresses unless you choose Share with IP Addresses, so there's no need to remove them by hand.

Enjoy the tools this weekend. I'm looking forward to your feedback on Monday.

Igor
