## What is Tank Mate?

Every aquarium has a story. Keep yours together with Tank Mate.

Track water quality, care routines, inhabitants, and photos in one app for freshwater, planted, marine, and reef aquariums.

YOUR TANKS, ORGANIZED
Give each aquarium its own photo, water tests, notes, reminders, and inhabitant log.

SEE CHANGES OVER TIME
Choose your parameters, set ideal ranges, and explore interactive graphs with pinch-to-zoom and exact reading selection.

TOOLS BUILT FOR AQUARIUM KEEPERS
Plan water changes with evaporation and a finishing reserve. Calibrate salt-mixing estimates to your own salt and scoop. Calculate aquarium, sump, and refugium volumes, account for rock and sand displacement, and estimate sand-bed requirements.

KEEP TRACK OF YOUR INHABITANTS
Search common-name suggestions or add your own. Record quantities, photos, observations, and moves between tanks, with advisory compatibility notices for supported species.

YOUR RECORDS, YOUR CHOICE
Work offline, enable optional private iCloud sync, or export a separate backup with photos. Available original Tank Mate records migrate automatically when you update.

Make it yours with light and dark appearance, accent colors, and matching app icons.

No subscription. No separate Tank Mate account.

### 1/5 — bad app

*2022-09-06*

Not recommend you can maintain your fish tank in your notes this app does not help just a fancy way of taking notes of your tank just in an app that’s all 🤦‍♂️

### 4/5 — Review

*2019-04-26*

I’ve been using this since starting up my new FOWLR last October, it’s perfect for storing test results each week so that trends can be seen in a graph form when needed. I don’t use the salinity calculator as I use natural sea water. 
One addition i would like to see would be the ability to upload photos with test results to monitor changes over time.

### 4/5 — Good app

*2018-04-20*

App works well for tracking routine maintenance,but it would be better if it had a section for adding information on tracking livestock

### 3/5 — Great but could be better

*2018-04-09*

Great app!! the only thing I would like to really see is a graph that shows all my element levels on 1 graph not 1 graph for each element. Other than that so far I’m happy.

### 4/5 — 4 out of 5

*2016-12-16*

The push notifications, if enabled, are great reminders for my various daily, weekly, and monthly reef tank tasks. The calculators aren't really all that helpful though.

### 5/5 — Best Aquarium Log App out there

*2015-12-03*

This is by far the best app for keeping track of everything to do with your aquarium/s.
It's easy to use & setup and the customer support is fantastic.
I can now keep all my logs of all the water parameter tests for all of my tanks in 1 place, and the graph makes it very easy to see any differences in the test results.
Plus I can add & keep track of all my notes, eg maintenance carried out on which day, for the tanks AND set reminders with an alarm for when things, eg check filter wool, need/are due to be done.

### 5/5 — Amazing

*2015-08-18*

Tried a few other similar apps and nothing compares to the ease of use and options included. Should be triple the price. It's a steal @ the current price. Don't miss this ones your aquatic friends will thank you!
