Fintech Mobile App Development in Exeter

Consumer and business financial apps for Exeter fintechs. Authenticating a payment on a phone carries a requirement most teams meet late: the approval must be bound to the specific amount and payee, so a customer confirming a fingerprint has to be shown what they are actually authorising, not just asked to confirm.

Why this comes up

The problem

The app authenticates the user beautifully and then asks them to approve a payment described as "confirm transaction".

What you get

What we deliver

  • Payment approval showing amount and payee at the moment of confirmation
  • Biometrics bound to the device and re-established when the device changes
  • In-app copy about products treated as promotional material, with the checks that implies
  • Fee and cost information presented before commitment, not in a linked document
  • Fraud warnings placed where the risky action happens
  • Account recovery designed against the way accounts are actually taken over

Fintech Mobile App Development in Exeter — common questions

What does binding an approval to a payment mean?
The customer must be shown the amount and the recipient when they authenticate, and the approval must be valid only for that payment. A generic confirmation prompt does not satisfy it, and it is one of the more common findings in app reviews.
Is a fingerprint enough on its own?
It is one factor, combined in practice with possession of the enrolled device. What matters is that enrolment is properly tied to that device and re-verified when the app moves to a new one, since device change is where account takeover concentrates.
Do the promotion rules apply inside the app?
Where the copy invites someone to take up a financial product, yes — including onboarding screens, upgrade prompts and notifications. Teams treat in-app text as product design and marketing text as regulated, and the distinction does not exist in the rules.
Where should fraud warnings go?
At the point of the payment that fits the risk pattern, not in a general notice at sign-up. A warning shown when someone sends a large amount to a new payee for the first time changes behaviour; the same words in the terms do not.
Do you work with businesses across Devon?
Yes. We are based in Leicester, United Kingdom and work with clients throughout South West, including Exeter and the surrounding Devon area. Most collaboration happens remotely, and we travel for kick-offs and key milestones.
What kind of Exeter businesses do you usually work with?
Field service scheduling and routing for businesses covering a wide rural patch, plus professional services systems. Beyond that we work across Higher Education, Professional Services, Healthcare, Retail and Environmental Science.
Do you cover the areas around Exeter?
Yes — we work throughout South West, including Plymouth, Truro, Bristol. Exeter is an urban area of roughly 130,000+, and we take on work across the wider Devon region rather than the city boundary alone.
