Test on your phone
Scan a QR code to open your running preview on a mobile device.
Desktop previews hide the problems thumbs actually hit: tiny buttons, wide tables, forms that fight a phone keyboard. Every running web preview has a QR code in the Preview Hub — scan it and the same isolated app opens on your phone.
Scan and use it
-
Start the web preview in the Preview Hub and wait until it is ready.
-
Open the QR panel on that preview card and scan it with the phone camera. You can also copy the preview URL and send it to yourself.
-
Use the app as staff or customers would: one hand, small screen, mobile data. Note what breaks, then annotate or describe it in chat.
The URL is a real address on the public internet, so a colleague can open it too — no Evonx account required. That makes a short feedback session possible before anything is published.
