Well the other reviewers had me scared to death but I finally parted with my $.99. Whats all the complaining about. I have an iPad Air and a good internet connection (Uverse with consistent 11.30 Mbps) and I was surprised. Browser speed was decent and I am able to Cast some videos that other apps couldnt. Some suggestions to those having trouble. Use the A/C power for your Chromecast (not the USB) and download a Speedtest to check your wifi speed. Good chance your problem is not with the app. This applies to most apps. Not just this one.
