BariBuddy is a free app that is of course available for both iPhone and Android. The app is available in Swedish, Danish and English and it is the language of the phone that controls which language the app has. Users who have Norwegian as the language in their phone will receive the app in Swedish other languages that the app is not translated into will receive the app in English.
Behind the app are Carl-Magnus Brodén who is a doctor and Joanna Lenner who is a dietitian. Both work at Sweden's largest clinic in obesity surgery, where approximately 700-1,000 obesity surgeries are performed each year. They have developed the app together with the company Baricol Bariatrics, which designs tailor-made products and services for people who have undergone obesity surgery.
