What does this mean? "Authentication Failed. Calenmob could not log in..."

[iMore Question]

I bought the calenmob app yesterday and downloaded it onto my iPad and iPhone 5. Whenever I turn these devices on, a box appears on my screen that says "Authentication Failed. Calenmob could not log in, please check your user name and password". And then a single click to "ok"

I don't know what this means or what to do. Any help is greatly appreciated.

It seems you need to enter in your Google account log in
