What is a plugin or application for a phone to display a design from photoshop to a mobile phone?

Question

User interface

Hello. I remember once I was designing a phone app, and I used some kind of plugin or phone app that synchronized the screen in photoshop and on the phone. You could immediately see on your device, the result of the work ... I can’t remember now. Haven't done this in a long time. Maybe someone came across.

Answer 1

In the latest 3-4 versions, there is a built-in thing.

Answer 2

Try to start using InVision. It is not "on the fly" but a handy thing

Answer 3

Pixl Preview works great.
