I have created a website to help people suffering from heartburn and GERD so that they can keep a log with the relevant information whenever a heartburn episode occurs:www.heartburnlog.com
I initially created the website for me as I do experience heartburn episodes occasionally.
The site is at early stage, but soon it will include analytics so that you can discover patterns in your log history - for instance discover which combinations of food and drinks appear recurrently, and get some insights whether the remedies you are taking are working for you.
I would be very glad if anyone is interested in beta testing the website and provide feedback.
Hopefully this website will help users achieve a better quality of life.
