Download the iSolved Go app from the Google Play store (see the attached image) and install it. On the login page of the CTR app you enter the email address you used when setting it up, and the password you created during setup. Check the Remember Me box so you don’t have to re-enter this info every time. Also on the login page you will see a gear in the lower left corner . Tap on the gear and type CTR in the box below Network Partner, then tap the Save button. Each time you setup a new device CTR will send you a code to verify that it is you. You should only have  to enter the code once on each new device.
