The new Nutribook patient app puts the diet a nutritionist writes in Nutribook straight onto the patient's phone. Patients see the day's meals, swap foods within the alternatives their nutritionist allowed, build a shopping list and follow their progress between visits.

Context

An app worth a place on the home screen

An app worth a place on the home screen

Nutribook is the most widely used software among dietitians and nutritionists in Italy. They came to us with a very specific brief: design and build an app that connects patients with their nutritionist and shows them their body measurements and, above all, their diet.

It couldn't be a bare-bones app made only to give access to a service. It had to earn its place on the phone, next to apps from the biggest brands.

Decision

Freedom, inside the nutritionist's limits

Freedom, inside the nutritionist's limits

A diet from a nutritionist is more than a few meals and a list of foods. It's a carefully thought-out plan that comes with a shopping list and, above all, alternatives.

So patients can put their diet together day by day, week by week, choosing what suits them, while always staying within what their nutritionist told them to do.

The hard part

Made for patients who aren't tech people

Made for patients who aren't tech people

Many patients aren't comfortable with technology, so there are no passwords. They join from an invite sent by Nutribook and sign in with their email and a code by SMS. The diet stays on the phone without a connection, and their changes sync when they're back online.

Let’s create

great things.

How do you work?

We keep things transparent and collaborative. We share updates consistently throughout the process, so nothing comes as a surprise. Weekly 1-to-1 meetings keep the work aligned and give space to review what's been done and plan what's next.

Why should I choose Heterochromia?

We work fast and we have an opinion. We don't just ask "what do you want?" and execute. We guide you through the process, challenge your assumptions when needed, and help you get to something better than what you imagined. Damn, we love what we do.

Do you do outsourcing?

Over the years, we have met a lot of talented people. Some of them work with us regularly on projects that require specific expertise.

What timezone are you in?

We are based in Milan, Italy (CET/CEST), but we work with clients in the USA and Japan with full flexibility.
