Yes, I managed to send them an email ( to their publications reviewers) and I got a reply thanking me.
They will make sure that my feedback gets forwarded to their app designers.
That sounds like a great idea.
Have you let Macmillan know? I've found some information about contacting them on their website, which I hope can help: https://www.macmillan.org.uk/about-us/contact-us/how-to-find-us.html#310046
Take care, Becca at Breast Cancer Care.
I have just downloaded this App. It’s very useful for keeping everything in one place. I just wish it had a way of tracking my reactions to my treatment (a colour coded key of symbols on a calendar) just like the menstrual cycle app that I use has.
