Combining two mobile apps for a unified experience

Commonwealth Bank had two mobile apps where the Commbank app was used by majority of CBA’S mobile customers despite being limited to features that Kaching provided. Due to the overall usability and functionality of Kaching, the decision was made to align Kaching’s designs to the Commbank app to unify the two apps.

Working within a team of 3-5 UX designers, a concept was created to introduce a dashboard which surfaced payment options as they were the most used features (which also included Kaching’s social payments) and an off-canvas navigation to separate the users’ tasks.

The work was laid out to plan and sort the screens which required changes as well as the measure of how much effort it would involve.

Flows for existing screens which required header changes or new component designs were included.


New flows were created which included an improved registration process and on-boarding to the new app.

A specification document was produced for all screens with annotations and interaction details.
