The App is simple and works for most part. Sometimes it throws out an Error Message and you have to start all over. Worst thing however is that is does not keep you personal data, you have to enter everything all over and over again. There is no "profile" function and no "my bookings" overview. It is just another interface to the regular booking site. Also it does not allow copy&paste in fields like phone number and creditcard number. Therefor no reason to install this app as it does not bring any benefit towards the regular booking webpage.
