Use it almost every day.

I bought this app when I first got in the trade and have used in countless times since. Very quick go-to when a code book isnt handy. Ive also contacted the developer with a request for a new module and they provided a quick friendly response and the module added the next day. This app may seem pricey, but I find it indispensable and recommend it to all my fellow sparkys.
