This app is essential for anyone following the fast tract diet to address reflux and IBS. It’s easy to use and helps to keep track of pretty much everything you eat and any symptoms you may have. Plus it sets out the basics behind the theory of the FTD. It works without any hitches and the only reason I’ve given it 4 instead of 5 stars is that I’ve been told it’s going to be updated shortly and will have even more possibilities in the next version (more foods and more symptoms).
