I just looked into aquatic log, it looks pretty cool, the only thing for me would be the yearly cost. Just a simple way to track and graph my parameters is all I'm looking for so aquarimate works well for me. I did discover another issue with the app, which I plan to email them about, is that you have to manually tell it to back up your data. My phone broke and I got a new one this week, fortunately I realized this before I sent my old one back, and I just put the sim card back in the old one and backed it up. However, from what I can tell, if you lose your phone, you'll lose everything since your last backup.
