Very useful app, needs FAQ

I’ve been using this app for 18+ months. I really like being able to compare values across months of tests on the graphs. I’ve figured out how to change dates and expand the graphs, more or less by trial and error as the FAQ for the app isn’t extensive.

So far I haven’t lost a single piece of data covering my reef tanks or my freshwater tanks. My only complaint is the update that broke writing notes, but that seems to be fixed.

Give it a shot

The instructions for running various tests are great! I really like that there are color samples to help you compare your results. LFS finder is great too. Setting a date range to view your tests isn’t quite as intuitive as it might ought to be. Hoping the app will continue to develop overtime with additional features.

Awesome app, great features easy to use!

I love the ability to look up stuff through critter ID in the app. Doesn’t just take you to the web browsers. Definitely worth the money for keeping your reef on track.
