Fair Finance

A mobile app for Fair Finance, a UK lender. Customers work out a loan, apply in three steps and then repay it from their phone.

About the project

For Fair Finance, a UK lender offering a fair alternative to expensive payday loans, we designed and built a mobile app for iOS and Android. New customers set the amount and term in the calculator and instantly see the monthly or weekly repayment, the fees and the total to repay. They apply in three steps, then follow the decision in the app, upload their documents and sign the contract. Existing customers log in with Face ID and see how much is left to repay. They pay an instalment with one tap, can settle the loan early at no extra cost at any time, and borrow again with a higher limit.

Strategy: UX strategy, a simpler loan application, clear terms in line with FCA rules
Design: UI/UX design, mobile app (iOS and Android), design system, clickable prototype
Client: Fair Finance
Technology: Swift, SwiftUI, Kotlin, Jetpack Compose

Design notes

11 screens: welcome, log in, calculator, application, application status, home, payment, repayment schedule, documents, profile and help.
The calculator updates the repayment live. New customers can borrow £400 to £1,000 over 6 to 12 months, existing customers up to £3,000 over 18 months.
The application has three steps and a clear consent to a credit check. It can't be submitted without it.
A timeline tracks the application from submission all the way to payout. Customers get a notification with the decision; in the demo, a button moves the application along.
The representative example, the APR and the FCA regulatory details are always one tap away, as UK rules require.
Bricolage Grotesque for text, DM Mono for figures, and two colours: blue #2D57E5 and a warm yellow #FECD5C for what matters most.
