I actually tried to cancel on the app but couldn't find any way to do so. I did try to use it as well, but it was rubbish so I couldn't
Did you email them or google how to cancel a Tastecard?
I have had one for about three years (I’ve never paid more than £1 for trial, normally it’s free). I live near an area that has a lot of chain restaurants in a marina with lovely views so eat there quite often. I meet my friends in the evening or have a relatively inexpensive lunch out (around £24 for both of us). It’s also handy for cheaper cinema tickets, I have an unlimited card but then I can get my friends a cheaper ticket.
