Overview
Banking app development brings together UX, security and integration: an app must be simple enough for every customer, secure enough for a financial institution and connected to cores, payment systems and partners in real time. We design and build banking apps for web and mobile, including onboarding, account management, payments, cards, notifications and in-app support, backed by APIs designed for them.
Common use cases
- New banking appApps for a new banking brand or product.
- App redesignImproving usability and ratings of an existing app.
- Wealth or savings appFocused apps for savings and investments.
- Companion business appMobile approvals for business banking.

Frequently asked questions
How do you ensure banking apps are accessible?
We design to WCAG guidelines and test with assistive technologies on both platforms.
Can you improve our app store ratings?
Ratings usually improve with faster performance, fewer login problems and clearer journeys — which we measure and address directly.
Do we need a banking licence to launch a neobank?
Many neobanks launch in partnership with a licensed sponsor bank or e-money institution, while others hold their own licences. That is a legal and strategic decision for you and your advisors; our platforms support both models technically.
Can you integrate with our existing core banking system?
Yes. We build API layers and middleware over existing cores, or implement a modern ledger alongside the legacy core for new products.
