Although every effort is made to ensure correct functionality, this cannot always be guaranteed. Please ensure that the trapp is suitable for your use, remembering that they are targeted to train students in getting over a particular area of difficulty. We cannot provide refunds as it is anticipated that once the trapps have been used for a while, the student will become more proficient in the area they previously found difficult thereby making the need for the trapp redundant. Feedback is welcomed in terms of adding functionality to downloaded trapps, which could be made accessible at no further cost from Apple's App Store.
