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.

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!

Thank you for your feedback and kind words! Multi-device sync is in progress, and I’ll work on adding data export options for measurements, livestock, and maintenance history in future updates. Your suggestions are greatly appreciated! 😊
