One of the best tools for JSON

I normally don't review applications, but this app is great. I find it very easy to use JSON now thanks to the simplicity of this program. I highly recommend this to anyone who uses JSON.

I have been working with JSON data and Xcode and was delighted when a fellow developer recommended this. I couldn’t imagine not having it now.
