  • Period: 7 months.
  • Client location: US.
  • Business model: Dedicated team.







As a cashback application, brands and retailers can use this tool to connect directly with shoppers. In return, shoppers get to bring home the healthy and sustainable products they desire while saving money on their purchases.


Client background

This app is more than a coupon platform. It stems from a US team that envisioned an easy way for people to discover healthier, sustainable products while connecting with like-minded people and building something positive together.


Business challenge

Shrink’s main challenge was to connect app shoppers, retail, and brands in one app while providing each segment an advantage by using the app.

The Solution

Perpetio created a location-enabled app that offers shoppers a cashback service for buying health products. Retailers can add Shrink labels to their existing loyalty program, replace clipped coupons with swipe-able digital cards, and increase the total amount spent by natural product shoppers. Thanks to hashtags and recommendations on social media, users can help brands become famous.

UI Design

Once we tested and found all usability іnaccuracies, we began creating the UI design for app screens.

We applied a fresh and light visual style within the color pallete agreed upon with our client.
All screens were made for both IOS and Android platforms. Our design team followed the Material Design and IOS Styleguide.


The Result

This app is a useful and feature-rich solution for both retailers and shoppers. Shoppers can now find the most suitable products to meet their unique needs while earning cash, rewards, free samples and even recipes.

One of the best advantages for retailers is the ability to engage with consumers before they shop, when they shop and after they shop. The app also provides special rewards to loyal customers and helps brand-loyal shoppers find their products in just a few clicks.
