Aquarium Assistant

★★★★★ I tried every aquarium app I could find, paid and free, and this was one of the best. Great little app for keeping track of what's happening with your aquarium. I really like on the parameters graphs that you can have up to 3 different ones on the same graph. So if you're cycling your tank, you can have ammonia, nitrite, and nitrate all on the same graph to easily see where your at in your cycle.

★★★★★ I think I tried all the higher-rated aquarium management apps on the Play Store. This one is by far the best. Very easy to use and has a pleasing user interface. Unlike most others, this app is highly customizable and allows you to track (or not track) water parameters, livestock, plants, equipment, costs, EI ferts, and more. It also has about 20 different calculators and a bunch of unit converters. The only two things I didn't really care for are the database area and the account area. I signed up for an account, but it doesn't do anything. The database is woefully incomplete. There is absolutely nothing in the library directory, the plant index is extremely small, the fish index is much better, but still incomplete. There is a video section also, but unfortunately all the videos are in what I believe to be Polish language. It's not like I was planning on using the database often, but it would be nice to have a better database since it is a feature. The advertisements aren't bad at all. A banner at the bottom and an infrequent shippable video when exiting. But, I went ahead and purchased the app to support the developer. It really is the best aquarium manager on the Play Store that I've tried.

★★☆☆☆ When I do multiple water tests in the same day, the charts just equally space each measurement, so three tests in a row look the same as one test every day for three days. The x-axis needs time, not just date. Edit: I'm not sure how your variables are set up, but couldn't you just linearly interpolate between the two days? Every measurement shouldn't be equally spaced.

★★☆☆☆ I feel a 2 is harsh. But then again, that's just related to how I use it. Currently totting up my expenses and about it really. Can't edit the sections at all so practically just a basic notepad and calculator. There are various calculators for water chemistry that some will find useful but too complicated for me and not any guidance. Some volume calculators etc., useful but prob a use once thing. Feel this started with potential but then died and not updated forever
