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 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.
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.

Flat Tummy didn’t just need an app — they needed a tool that felt like an extension of their users’ lifestyle. By giving their audience workouts, meal planning, and shopping in one polished platform, the brand leveled up its digital experience. It’s now more than a brand — it’s part of their users’ daily routine.
