What's New in Radien

1.10

September 16, 2026

Every screen now works at the largest text sizes. Set Larger Text as high as you like: Radien changes its layout instead of cutting words. A host field grows to fit its font and its button moves above it, result rows put a value under its title rather than squeezing it into a column, the 32 bits of an IP address take one octet per row where each bit is big enough to tap, and the home card puts your status, address and router on lines of their own. Options sheets, help sheets and Network Details follow the same rule, in all nine languages. Nothing changes at the default text size.

User reviews

Very handy little utility!

I've been getting more into network utils lately and was happy to have stumbled upon this. The UI is simple and clean, works as advertised and works flawlessly with the VoiceOver utility.

If you are doing network diagnostics, Radien is definitely worth your time.

Response from developer

Thank you! The VoiceOver line made my day: Radien's accessibility was shaped by blind and low-vision testers from the AppleVis community, so "works flawlessly" is the sentence I was hoping someone would one day write. If a diagnosis ever leaves you missing a tool, write me at radien@arsenkin.name. I read everything.
