Reef Tank Pro Iphone App Review

So I needed somewhere to store all my tank parameters as well as additions and deaths in my tanks. I'm good with excel and had created a couple sheets for that kind of stuff when I was working as a pool supervisor so I modified them to fit my needs with Reef Keeping. They work good for what I need, but I wanted something that I could easily carry with me as well as keep pictures of things as I add them to the tanks. I looked around and tried a couple apps, but the one that got me was the $5 app Reef Tank Pro by Eric Cosner. I liked the look as well as the capabilities it had. I've been using it now for well over a year and it really fits well with my needs.
