not sure why i downloaded it but i no longer want it. i cant uninstall it from the app manager, and i cant find the application anywhere. please help and advise...

When you set it up (once you first installed it) you had to set a configuration password.

You need to send a text to yourself just saying that password and that will automatically start that config again. Once you've done that, there is a checkbox option to allow you to uninstall it, once you then save the config, it will be available to uninstall in the app manager.

If you've forgotten your password, speak to the developer as I believe he has alternative ways to recover it
