First impression

I just downloaded this and tried my first test, ammonia from Salifert. The linked video in the test section is wrong, you should check it, it shows Melev’s reef saying he should get more tests (?).

The instructions for the Salifert ammonia kit are for the NH4 kit, I have the NH3 which has different instructions. Maybe you could specify this because it might be confusing, all online stores sell the NH3 kit as standard ammonia test.

I will continue trying it out and report back.

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.

Pretty good overall, little room for efficiency gains.

I’ve been using the app for a while, very shortly after the initial release, and like it overall. The only suggestion I can offer is that it would be helpful if the app would retain test kit selections to save a few clicks.
