The iSpoofer is a wonderful application for iPhone and iPod Touch users. It lets you listen to high quality audio while travelling on the road or in a plane (I've used it on a plane before). It's incredibly simple and easy to use, but also features a large library of sounds perfect for travel. The main problem I have seen with it, however, is that the iPhone version doesn't seem to be as good as the one available through the website iSpoofer.
I started out by trying the free version of the iSpoofer but quickly discovered that it lacked a few important features - such as hooking up to a PC to transfer the sound over to headphones, and not having the ability to change the volume from your car stereo system. After finding several apps which claimed to have the necessary functionality I decided to give the paid iSpoofer pogo download a go for a couple of days. It was pretty obvious to me that the iSpoofer pogo download just wasn't anywhere near as good as the free one. While the free version still has some pretty impressive features, the quality of the sound produced through the iSpoofer iPhone version is very poor. If you want to use a car simulator application or some other kind of similar device in your car, then the iSpoofer iPhone version simply isn't worth it. If you want to use it to listen to music though, then that's probably going to be able to suffice.
The final part of the review I want to write is about the many different ways that you can use the iSpoofer. Because it's an iPhone app, it allows you to take the device wherever you like to travel - including being able to listen to music or take pictures of new places. The only major drawback that I've noticed so far is that although the iPhone version works quite well when connected to your car stereo, the iPhone doesn't seem to work at all when connected directly to the ipod. This may not be a problem for you, but it's something to think about if you're planning on using the Pokemon go journey on an Apple device.
