Frequently Asked Questions
What is PlainCast?
PlainCast puts your phone's apps on a big screen. Its signature feature, Parallel Screen, opens each app in its own window — so you can watch, navigate and chat side by side. Full-screen mirroring is there too when you want it.
What is Parallel Screen?
Parallel Screen runs your phone's apps in separate windows on the big screen while your phone stays free for normal use. You can even turn the phone screen off and playback keeps going.
Which devices can display it?
Anything with a modern browser on the same network: smart TVs and set-top boxes, car displays (including Tesla), laptops, tablets and phones.
Does it work on a Tesla?
Yes — the Tesla's built-in browser works. Open the address shown in the app on the car's touchscreen and approve the device, and your apps run right on the car display. Connect the car to the internet (for example through your phone's hotspot) so the page can load.
How do I set it up?
Install PlainCast, connect your big screen to the same Wi-Fi or hotspot, open the address shown in the app, and approve the device. No cables, no extra hardware.
Why does the first-time setup need Wi-Fi?
The first-time setup uses a phone setting called "Wireless debugging", and Android only allows it while the phone is connected to a Wi-Fi network — with only a hotspot, the switch turns itself back off. So for the first-time setup, connect the phone to any Wi-Fi (the hotspot of a computer or another phone counts) or use the Shizuku option. This is only needed once: after that, PlainCast works anywhere, even with just mobile data.
Does it use the internet or my mobile data?
Video, audio and input travel directly between your devices over your local network — never through a cloud server. If your big screen uses your phone's hotspot for its own internet, that traffic counts as usual.
Is it private?
Yes. Everything is end-to-end encrypted, stays on your local network, and every new device must be approved on the phone. Nothing is uploaded or stored anywhere.
Is PlainCast free?
PlainCast is a premium app on Google Play with a free trial — try everything before you buy. No ads, no tracking, no data collection.
Does it work with an iPhone?
PlainCast needs Android 14 or later on the phone — iPhones aren't supported, since iOS doesn't offer the APIs required. The big-screen side works with any modern browser.
Can I control apps from the big screen?
Yes. Click, scroll and type right from the big screen — your input goes straight to the phone. The phone's touchscreen keeps working too.
How is PlainCast related to PlainApp?
PlainCast is made by the PlainApp team. PlainApp is a full phone-management suite; PlainCast is a focused screen-mirroring app built for the big screen.
