Yonda: track your spending & earn cash rebates

Yonda is a free, contactless, pre-paid card controlled via the Yonda app, available on both iOS and Android. When users use their card at one of Yonda's partner retailers, restaurants or experiences, they will earn cash back as Coin, which can be put towards future holidays, treats and gifts. Most notably, the app enables users to track how much money they are spending, and how much cash they have Coined in and is headed their way.


Red C was commissioned by the Blackhawk Network to build iOS and Android apps for its new proposition, Yonda. Yonda is a prepaid card that encourages users to set a savings goal, clearly breaks down payments by type so they can see what they have spent their money on and then rewards them via loyalty cashback each month.

Red C worked with Blackhawk Network and its branding agency to create an optimal experience for Yonda app users. It was essential for us, and Blackhawk Network that the entire user process from 'sign-up', to topping up and using the card was as simple and user friendly as possible.

Additionally, ensuring that processes were secure when handling user's money was of the upmost importance to our client, and so, to enhance security we included Touch ID for both iOS and Android versions of the app.

In order to track the user's 'saving' progress we animated the Yonda illustrations to depict progress towards achieving goals in an engaging format.



Red C worked with Blackhawk Network and its branding agency to create wireframes for all the user journeys. We then created full visual designs for each screen, these were tested using InVision, an online prototyping tool. Once the designs were signed off Red C worked with Blackhawk Network's in-house development team to clarify and specify the API requirements. Additional API's were developed alongside the app development process using Jira to manage progress and resolve queries.


After a period of Beta testing with a closed group of users the app was released to the Apple App Store and Android Google Play store. The app has been very well received by the public with interest growing fast. Red C are working with Blackhawk Network to develop future enhancements for the app.
