no login-function, no use
The iPad app is lacking a login button, so that you can enter your details, but then never login...must be a bad joke. The iPhone app is capable of logging you in, but then is missing any option to add an existing booking or to simply check-in. Dear Cathay, suggest to look how Lufthansa, BA, Eurowings, etc. are doing it - even the KLM app is more usable.
