Ratings and reviews

Updated 08/02/26: Bumping from 2 to 3 stars. There have been some minor updates since November 2025. I really like this app. At one point I had given it 5 stars. However, I haven't seen many updates from the developer in several months.. It feels like there's almost no support for the app anymore. I've emailed several times asking if anything new was on the way and while I usually hear back quite quickly, these last several emails have received no response. It's been several months now.

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!

Excellent app for keeping track of animal and plant stock, but also for setting reminders or journaling maintenance. Downsides: I wish there was better multi-device sync functionality but dev said they are working on it. I also wish you could export data, not only measurements but also livestock data and maintenance history. Overall, highly recommended for aquarium enthusiasts and beginners!
