Rubbish - can't login as the password reset doesn't send an email - thought perhaps they have archived my login details (as last time I used it - it was a pile of pants) but when I tried to re-create the account I was advised that account was already in use! Absolutely rubbish. Will have to drive down to the surgery in the morning as otherwise it will be a 50 mins wait in their call queue. So much simpler when they would just pick up the phone!

A duplicate of the NHS app, not sure why I need two apps doing the same thing. Tried to book an appointment this morning and had to try several times as the answers to the questions are highly subjective and my answers several times led it to tell me to ring 999 - how much unnecessary work does this app cause to the ambulance service? Once I'd given the right answers, too late all the appointments had gone. I can't imagine how the elderly deal with this. Really poor.

Awful, badly designed app. I wanted to send a message to my GP which did not correspond to one of the offered categories so I wasted my time trying several different options none of which were helpful, ended up having to book a telephone appointment for something that could have been an email. So now I'm going to waste a doctor's time as well. Seems to have been designed to add barriers to deter people from contacting GP.
