What real users are saying
I cast my iPad straight to the projector in class — students can see all my drawings and annotations. No more turning around to write on the blackboard.
When clients visit, my laptop connects and casts instantly — way faster than hunting for an HDMI cable.
When my kid wants to watch cartoons on the phone, I cast them to the TV — bigger screen is better for their eyes.
I cast directly from my device for group meeting presentations — no need to copy files to the meeting room PC. So much easier.
I can update display screens at every store right from my phone — no dedicated staff needed. Saves a lot of hassle.
When I demo remotely for clients, I just open a browser and cast — no software install needed, very convenient.
