I decided to try this app to log all my aquarium parameters. Long story short: $10 wasted. The iPad app just plain does not work at all.
Also, if you have two devices like me (iPhone and iPad) the app does not share data between them. You have to log in (which is really clunky) and do a backup. Then grab your other device and do a restore. Oh and did I mention that it logs you out every time?
Really shoddy programming here.
Do yourself a favor and use anything else!
