Very organized, been very helpful when jotting down everything u do to your tank, the only thing I would change is if there is a note option for each inhabitant/fish only because I like the weigh my fish and I k this has to be a small percentage who do this. Not a big deal though.

Love this app!

I started back up a couple tanks and I found this app which makes managing them much easier.
The app is great! There are just a couple things I’d love to see. I have planted tanks so I want a place to track plants, what kind. when they were planted and bonus points for linking to care information from the internet.
I’d also love a place to insert pictures as I’m taking notes about the tanks. I want to have the progression of tank photos saved to the app.

Looks good

Just bought this because I need to keep track of tank and this has everything. $2 is much cheaper than a crash of my tank. Only con which isn’t a con is the ability to write down cost of equipment. I’m going to die knowing how much I’m paying for a reef tank setup.
