Beware of payments
The app in itself is fine. A bit dry in its style but thd kids occasionally get set it as homework, and O have enjoyed it myself on occasion however ...as others have said...it auto renews for paid services of which you have no recollection of signing up for! There are no payment reminders sent before payment taken and no way of finding any subscriptions on your account thus no way of cancelling anything before payment comes out. Thankfully, customer service have been swift to assist. I will be cancelling my accounts to ensure no future errors in payment though.
