What WETID does – in 30 seconds
WETID is a company based in Mutterstadt, Germany, that develops digital and analog tools for people with diabetes and other metabolic conditions: the free nutrition app MyDia, the WETID nutrient pocket book and the knowledge and community platform WETID Beyond – connected by Nori, our AI layer. Our goal is to make nutrition a dependable part of care, for patients, their families and healthcare professionals.
The problem
For diabetes, obesity or PKU, nutrition is part of the therapy. Yet between training sessions and the next appointment, patients are left alone with rules of thumb and estimates.
Our approach
Tools that work in everyday life: nutrition values in seconds, knowledge that is easy to understand, exchange with others – as an app, a book, a platform and training material, connected by Nori, our AI layer.
Who we serve
People living with a metabolic condition, their families, schools, childcare and nursing staff – and diabetes care teams, practices, clinics and partners from industry.
Our products
One company, several tools. Each one solves a concrete problem in everyday life with a metabolic condition. Availability today: German-speaking markets; an international version of MyDia is planned.
MyDia – the free everyday app for diabetes
Nutrition values in seconds instead of guessing: MyDia delivers carbohydrates, fat-protein units and portion sizes for more than 350,000 foods – and brings a nutrition report to the conversation with your diabetes care team.
- Barcode scanner, search and favourites for a fast daily routine
- Carbohydrates and fat-protein units (FPU) at a glance
- Diary and nutrition report for the conversation with your care team
- Kids mode for families, childcare and school
The app and its website are currently available in German. An international version is planned; partners interested in a localised version are welcome to get in touch.
WETID Beyond
The platform for knowledge, courses, recipes and community around nutrition and metabolism – across conditions, for patients and professionals alike – with Nori as its AI assistant. Multilingual from the start.
Get in touchThe WETID nutrient pocket book
Carbohydrates and fat-protein units in pocket format – for every moment when there is no phone at hand. Currently available in German.

Order the kitNori: the AI layer of the WETID platform
Nori is the artificial intelligence behind our products – not a single app, but the layer that connects knowledge, tools and your personal context. So that nutrition values turn into answers: easy to understand, usable in everyday life and with clear limits.
Nori does not work with arbitrary internet knowledge but with curated expertise from nutrition counselling and clinical guidelines, and with the WETID food database. What Nori knows about you is up to you.
Understand
Nori explains the links between food, metabolism and therapy in plain language – with sources and a clear note on where the limits are.
Recognize
A photo of your plate, a label or a recipe, spoken or typed: Nori recognises what you eat and delivers carbohydrates, fat-protein units and portions from the WETID database.
Accompany
With your consent, Nori knows your profile, favourites and diary. It can make patterns between meals and glucose curves visible or suggest meals that suit you.
Connect
One Nori for every touchpoint: in MyDia, in WETID Beyond, in the future in your own AI assistant and in reports for your care team.
What Nori does not do
No insulin or medication dosing, no diagnoses, no substitute for your care team. Nori explains and suggests; decisions are yours, together with your clinicians. Functions of a medical nature will only follow certification as a medical device.
Your data, your rules
Nori accesses personal data only with your explicit consent, revocable at any time. Your data is not used to train AI models; processing follows the GDPR with data processing agreements in place. Health data is treated as what it is: especially sensitive.
Today: AI image recognition, a meal planner and glucose analysis are already in use for MyDia Pro users in the WETID toolbox (German). Next: Nori as an assistant in WETID Beyond, then the connection to your own AI assistants via MCP.
Our vision: nutrition as a tool of care
Nutrition is part of the therapy for almost every metabolic condition – and in everyday life it is often the hardest part. In Germany alone, more than 9 million people live with diabetes and almost 13 million adults with obesity. The numbers grow; the time available in practices and counselling does not.
We believe that people who understand their nutrition and can apply it in everyday life receive better care. Not with more rules, but with tools that fit their lives.

Our goal
A platform that brings together patients, relatives, caregivers, healthcare professionals and industry: knowledge, tools, training and exchange – personalised and fitting each life situation.
Each condition has its own key figures: carbohydrates and fat-protein units for diabetes, phenylalanine for PKU. Our solutions show exactly the values that matter for a person – and Nori, our AI layer, turns values into understandable answers.
We are working towards certification of our software as a medical device under the EU Medical Device Regulation (Class IIa), so that our solutions can become a fixed part of care.
Our path
- TodayDiabetes
MyDia as the everyday app, community and material for diabetes care teams.
- NextObesity, prediabetes, GLP-1
Nutrition as a companion to weight and metabolic therapy.
- ThenPhenylketonuria (PKU)
When every meal depends on the phenylalanine count.
- HorizonDementia and metabolism
Conditions in which nutrition and insulin metabolism are linked.
What we stand for
Evidence-based
We work with medical societies, diabetes educators and clinics and gather their feedback early.
Made for everyday life
Benefit before numbers. Nobody should be reduced to values – our tools adapt to life, not the other way round.
Independent and transparent
Profits flow back into the project. Data is hosted on servers in Germany. We give no dosing recommendations.
Together
Community, education and webinars – for patients and for professionals. Care improves when everyone sits at the table.
WETID products are information and support services. They do not replace medical advice, diagnosis or treatment decisions.
The people behind WETID
From a family's need to help for thousands
When my son was diagnosed with type 1 diabetes in 2014 at the age of two and a half, counting carbohydrates and insulin became a daily challenge – for the family, the grandparents, the childcare centre. So I built WETID: first as a private project, today as an app that supports thousands of people with diabetes in their everyday lives.
To keep it well-founded, I trained as a preventive nutrition counsellor with a focus on diabetes and nutrition. In 2025 this work received the Thomas Fuchsberger Award from diabetesDE, the German Diabetes Aid.

Voices from practice
“WETID supports diabetes educators in training and counselling – with instantly available carb and FPU values, practical portion sizes and helpful material for everyday life with diabetes.”
“A father who is affected himself shares his knowledge through the “carrot app” and the pocket-sized book, which make everyday life easier for diabetes families. I recommend WETID to all of them.”

These include the free nutrition app MyDia, the WETID nutrient pocket book, information material for healthcare professionals and the platform WETID Beyond, which is under development. WETID was founded in 2014 by Heiko Scharfenort after his son was diagnosed with type 1 diabetes at the age of two and a half.
What is MyDia and what does it cost?
MyDia is WETID’s everyday app for people with diabetes. It shows carbohydrates, fat-protein units and portion sizes for more than 350,000 foods and offers a barcode scanner, a diary and a nutrition report for the conversation with the diabetes care team. The core functions are free on iOS and Android; an optional Pro version extends the feature set. The app is currently available in German; an international version is planned.
Is MyDia a medical device?
No. MyDia is currently an information and support service and gives no dosing recommendations. WETID is working towards certification of its software as a medical device under the EU Medical Device Regulation (MDR, Class IIa). Until then the app does not replace medical advice, diagnosis or treatment decisions.
What is Nori?
Nori is the AI layer of the WETID platform. It connects curated expertise from nutrition counselling and clinical guidelines, the WETID food database and – only with consent – the user’s personal context. Nori recognises meals from photos, voice or text, explains the links between food and metabolism and suggests suitable meals. First building blocks already run in the WETID toolbox for MyDia Pro users; as an assistant, Nori will appear with WETID Beyond.
Does Nori give insulin or dosing recommendations?
No. Nori does not prescribe insulin or medication doses, makes no diagnoses and does not replace a diabetes care team. Nori explains, calculates nutrition values and makes suggestions; treatment decisions remain with users and their clinicians. Functions of a medical nature will only be offered after certification as a medical device.
Is WETID available outside Germany?
WETID’s products are currently available in German and focus on German-speaking markets. The website wetid.de/en informs international partners, professionals and patients about the company and the platform.
