I have the Neptune Apex and you can control your tank from virtually anywhere you have an internet connection after some configuration of your Apex. There is a very thorough document out there for configuring the Apex. As Origami2547 mentioned there an app that can do it with as well (Android and IPhone), but you may not even need to use an app. I have a Evo can can monitor and control my Apex from virtually anywhere. At home I monitor and update programming in my loft and see the changes instantly. I can look at the status, turn outlets on and off, view graphs, change programming, etc. all from my phone with no app. There are so many possibilities!
