The Apex is the world's most popular aquarium monitoring and control system.
From anywhere in the world, with your internet-connected Apex system and this app, you can:

- Monitor the health of your aquarium by observing current and past history of your Temperature, pH, ORP, Salinity and much more (depending on how your Apex System is equipped of course)

-Observe your aquarium via connected IP web cams.
Enter key water testing parameters such as Alkalinity, Calcium, Phosphates, etc.

- Enter notes about observations of your aquarium, maintenance, fish health, etc.

- Remotely feed your fish, right from your handheld device!

- Monitor and control more than one aquarium - either yours or friends.

- Get immediate iOS notifications when something goes wrong in your aquarium (leaks, overheating, pH out of range, water level issues, etc.)

Any Apex System (Apex Jr., Apex Classic, Apex Gold, or the new Apex System)

Works great


It has worked fine for me from the beginning. Oh and your controls being greyed out is on purpose so you don’t accidentally change things. You will notice that you can unlock the coverings is you wish. This app has been really nice especially when I am away. I am really glad I got the unit

Typical apex quality

This is yet another failed attempt by this company to get this product right. Be prepared for a 1990s device setup experience in 2017. Everything from not recognizing your fusion credentials that you already use to authenticate through the web version of fusion, to not having an option to generate a link token so as to sync the ios app to your fusion account. A confusing ui and setup process to say the least. Sad there is no real competition in this area.



Been waiting for a real app for 2 years now. Was tired of having to re-login to the browser version . Plus now notifications will be great. Thanks Neptune team keep up the great work. My fish are thankful too!
