I could not get the app to work. I downloaded the app, installed the software on the laptop amd thats it
Here you go step by step:
Open up the "AT Remote Control Configuration Tool"
Select the "New Profile" button top left of the application.
A new tab with "Button 1" should appear, you can now edit this button to perform whatever function you wish.
Press the "Green Plus" button to add more buttons to the profile, each button will allow you to add another measurement function.
Once you have all the buttons programmed the way you like press the "Save Profile As" button and name your profile.
Then press the "Load Profile" button to access your recently saved personal profile.
Then turn the WIFI on your cell phone on and connect to the tracker network.
Once the WIFI is connected press the "Server Settings" button on the configuration tool (has a wrench & screwdriver in the icon). Press the start button, the ball should turn green.
Open up the remote app on your phone and connect to the server.
Once your connected you will be able to swipe side to side to access all of your created buttons.
As far as I know there's no app for android, but You can use any remote desktop app i.e. teamviewer, tightvnc or similar, there's lot of it. It's not the same but helps a lot.
