Flat Tummy is one of the most recognized names in women's wellness across North America. Known for their strong online presence and effective product line, they wanted to take things a step further by giving their audience a dedicated app, something that could bring fitness, nutrition, and shopping together in one easy place.

The problem

Where things stood.

The brand was doing great online, but users had to jump between platforms: following workouts on Instagram, manually tracking meals, and shopping separately on their website. It wasn't smooth, and it was clear they were missing out on keeping users engaged in a consistent, meaningful way.

The solution

What we built.

We created a mobile app using Swift (for iOS) and Kotlin (for Android) to ensure smooth performance and native feel. Inside the app, users can follow structured workout routines, stay on top of diet plans, and shop Flat Tummy products, all without switching apps. It's fast, clean, and designed to support daily health habits.

Goals

What we set out to move.

  • Build a mobile app that brings everything together, workouts, meal plans, and their product store.
  • Make daily fitness and nutrition feel effortless and personalized.
  • Turn app users into customers by making it easy to browse and buy products without leaving the app.
  • Keep the visual style and experience true to the Flat Tummy brand.

How we did it

The shape of the engagement.

  • Designed a bold and easy-to-use interface, tailored to the brand's visual style.
  • Integrated Firebase for secure login, progress tracking, and personalized notifications.
  • Connected the brand's Shopify store directly to the app, allowing users to browse and order products from the same place they track workouts.
  • Set up analytics tools to understand what users loved, and where we could improve.
