What does this app do?

The FODMAP by FM app guides you through each stage of the diet (Restriction, Re-Introduction, and Personalisation) and provides you with details of which foods are suitable and which ones you need to avoid.

The app can scan food barcodes to help you find suitable food products and uses reaction ‘smiley’, ‘neutral’ and ‘sad’ faces to identify whether the food product is suitable or not.

Other key features of the app are:

  • Discover every day products you can eat
  • Portion guidance for specific foods
  • Record and track symptoms
  • Create personalised dietary profile
  • Watch short videos that detail how the low FODMAP diet works and how to follow it
Can I follow the low FODMAP diet using this app alone?

The diet is not recommended to be used without specialist dietary advice from a registered dietitian. This app should be used in conjunction with the advice the dietitian has given you to support you with the food choice you need to make. It can also can help you monitor and review your symptoms as you follow the different stages of the diet.

You do not have to use the app but some people may find it helpful when selecting suitable products in supermarkets, tracking symptoms and following the different stages of the diet. 

Where can I buy this app from?

This app is currently available on the Apple and Google Play stores and costs £3.99. You can download it by clicking below:
