I have this app as well, but rarely take the time to use it. If something is off in my testing, I just use my dry erase board until I get it back in line.
I use an older program called AquaLog on my computer. It was free to download. It doesn't have a bunch of fancy bells and whistles but it is much easier than keeping an actual book and I didn't have to format a spreadsheet. I am very glad I started to record things onto my log, as much as I smoke I can never remember what day I did what to my tank, my log keeps my tank strait when my head isn't.
I use an excel spreadsheet for now. When neptune releases their parameter logging feature in fusion (should be in the next month or two), then I will just do everything there so I can do everything from one interface.
