    This is exciting! I spent four years with body pain and told I had Fibromyalgia only to find out that my thyroid medication needed to be adjusted!  I cannot wait to try this app out and keep track of my symptoms! That way, I have something to bring to my doctor. It is difficult to get doctors to listen to me!

    What fantastic idea! This would definitely be a huge help in our daily lives. Let me add that you are a wonderful husband to be this concerned about your wife's well being. Most spouses or partners don't have a clue as to what we go through and deal with on a daily basis. Thank you!!!!

    This sounds amazing! I currently use 2 different apps to manage my health, neither of which are designed for thyroid stuff, and even between the 2 of them they don't quite do what I'd like. I've looked at many of the existing apps for thyroid and found them to be too basic or limited in their scope. I like how your symptoms page is formatted and how easy it will be to record symptoms. I'm really excited about how good this could be.

The Butterfly Story

My wife has suffered Hypothyroidism for many years, but its only over the past 12 months that we really understood that. It’s difficult to get the right treatment in the UK, but we’ve been very lucky to have spent time with Dr Barry Durrant-Peatfield, who has helped enormously.

But therein lies the problem. In order to design the correct regime for my wife to follow, Dr Peatfield needs a wealth of data. Both my wife and I have struggled with keeping track of various paper diaries, private tests, medication schedules and symptom tracking. At times of great stress, and when the brain fog descends, its the last thing we need.

What’s missing is a way to bring all of those things together in one place, and so the idea for Butterfly was born...
