App Reviews from Marketplaces

Marcelo Machado

Finally i found a program that screen the device screen to ubuntu 20.10 but…. is possible do the oposite? share the pc screen to cellphone? im thinking use that to use the “VR cardboard” for doplhin emulator or other similar….

Claude Gaborit

Very easy to handle. I just made a try in between laptop sous UBUNTU and tel huawei via the wifi network of the house. DIRECT succès without any hassle. Simple and efficient. Congratulations.

Disaster Area

Terrific! Runs smoothly. No problems at all. I got the Windows version for a few euros. I’m very happy with that too. I can’t transfer sound. But since I don’t need that anyway, I didn’t delve very far into the settings. Maybe will go. So thanks to the developers! A really very helpful app!

Philipp B

An earlier review of mine (I don’t see it, I hope it doesn’t appear here after 2) was completely unjustified and very negative. I simply didn’t understand how the app worked. The app must be installed on both devices. She wasn’t with me. Now I understand the app and use it to mirror the display content of the tablet to the TV via Chromecast. For example, I can play Baldur’s Gate or Sanitarium on the big screen.

Torsten Arendt

Works without problems. Very fast transmission.

pc pete

Works great as described on Samsung phone and tablet, on Xiaomi and Realme phone

T “Low” Jenkins

Works just fine for me. I read the instruction

Márcio Silva

Great app! Very easy to use. The connection is very good according to the devices I have connected. An important tip… Be careful not to leave files and your password visible when transmitting your presentation, etc.

Elena Makhinina

An interesting program, there are instructions in Russian, everything is clear. Everything connected and worked for me right away. I recommend!

Works fine with Windows 10 and Android 10. I would like also to be able send most clicks through this app. But view cart is also useful. It is very good that by default low quality because this is faster.

Jay M

For some daft reason screen mirroring was removed from Android TVs released after 2020, i tried so many apps to bring it back and none worked. There was a few apps that would connect but then just disconnect. So i wasnt expecting alfacast to work either but its currently free so got nothing to lose by trying it. Turns out not only does it work but it works every single time. I just wish there was more settings for things like fullscreen and display orientation. cheers dev/s

Imane Oussaide

It’s interesting and effective

Manjushri Bodhisattva

So far it works great, ‘out of box’, just run it on both devices and be on the same network. It seems all the bad reviews are from people that did not understand what the app is actually for… Screen/Audio Streaming from one Android Device to another (or to/from a desktop pc). It is not a movie player, use VLC… It is not for your XBox, use XBox Link for that… Steam Link for Steam. You get it.

Manuel Jesús Muñoz

Very good app and easy to use. If you meet the compatibilities, it will not cause problems. Obviously if you use very old devices, they may not be compatible, and I think that is the reason why some users give it few stars. 100% recommended!

Vladimir Kai

The only app that worked for me! Thanks to the developers!

David Moreno

This is good, it fulfills the function of reflection.

Es Campur

Very useful for switching screens

Ekrem Demirel

In one word, perfect.

Luiz Ricardo

Excellent!! I’m casting Android to iPad IOS. For some reason it doesn’t transmit with audio. Only with microphone. If you can, please help with the configuration. Abs

Washington Rodrigo

This app is very good, I’m even going to buy the 4k version, I really loved it, the only one that didn’t leave it talking about the Xbox one ❤️🥰💪🙌

Jurgen JUROVSKY

Works both ways without problems, connects quickly Sony smartphone+ Huawei tablet video from the screen is transmitted with a delay to another screen without sound or haven’t figured it out yet no advertising
