At Numbrs, we set out to redefine banking. Our multi-banking mobile app became the #1 finance app on the German App Store with more than 700.000 downloads in the first 8 months.
I built a UX team of 4 truly awesome designers that is in the forefront of defining product strategy and designing new features and improvements.
I designed several of the core features of our app for both iOS and Android. The design process I follow is highly iterative, working very closely with management and the cross-functional teams. I use research, validation and customer feedback to inform design decisions.
Due to my NDA, I can only share a very limited selection of designs.
I designed the current send money flow for both iOS and Android, a project that resulted in a huge lift in engagement, and received very positive user feedback.
Here's the final interaction:
My goals were to improve the adoption rate and to drive repeated usage.
In order to achieve the goal, Numbrs had to offer a clearly superior send money experience to other mobile banking apps. We also needed to build trust to make our users feel confident making financial transactions with a third-party app.
To guide my design process, I laid down some guiding principles:
Following my research and the concepting phase, I created the skeleton model for the feature:
I refined the flow into lo-fi wireframes first:
Lastly, I created the hi-fi wireframes and prototypes to test the flow.
The new send money flow introduced new interaction patterns, especially by merging the flow for contact search and new contact creation. To validate the proposal, I created an interactive prototype and tested it with a handful of people. The tests (and later hard usage data) confirmed that the interaction was immediately clear to users.
