I still consider myself a newbie since I've only kept fish now for a couple of years. This application has made my life so much better. in those two years I have progressed from 1 five gallon, to a 7.5 gallon, and now a 10 gallon. Now with all 3 I really need the app to keep everything organized and track any issues. Thanks so much for this application and all the work you do to keep it growing and developing.

Whatever you need to know, or keep track of, regarding your aquarium (or fish) is included in this app. Don't waste time trying other apps ... this one is the absolute best. I have four tanks, and this app is both a time saver and keeps all related information in one place, so it is easy to track and monitor. In addition, the developer keeps updating and adding better features ... something you seldom see with apps ...

Although there are still many shortcomings and it may be difficult to use, thank you for writing such a good review. I will continue to improve it.

This app is great! You can customize what's in your tank, your maintenance, your equipment, set water quality measurements that are recorded in a graph, keep notes and a diary, save pics, and set reminders. They have a large database of fish, plants and invertebrates, most of which have detailed descriptions of what it is and how to care for it and you can add new things to the database that aren't there. You can also save your data to cloud. I strongly recommend this app for aquarium hobbyists!
