1. SBI Bank’s 25% Increase in New Users
[Source: Surf]
Challenge: SBI Bank needed to revamp its outdated family banking app to attract more users. Surf was tasked with developing a native app from scratch that’s simple enough to be used by non-tech-savvy users as well, with a focus on shared accounts, budgeting, and financial education.
Solution: Surf built a new mobile app with modern, pastel-themed visuals. The team integrated features such as shared accounts, task-based rewards for kids, and family-wide cashback programs. The app was envisioned as a transparent family banking tool where the main account owner can monitor linked cards, set individual spending limits, and track expenses.
Results: Compared to the old app, the solution saw a 27% rise in monthly active users and a 25% increase in new users. In 2022, the product was also voted a notable family banking product, boasting over 9,000 users.
2. A Fintech Startup’s Successful Launch with 3,000 Users
[Source: Surf]
Challenge: Pakistani fintech startup sought to create the country’s first neobank app and provide accessible digital banking services to the largely unbanked population, targeting tech-savvy millennials.
Solution: Surf developed a Flutter-based app that allowed virtual and physical card ordering, remote verification, online transactions, and bill payments. The mobile solution introduced several essential features previously unavailable in Pakistani banks, including transaction history, bank-to-bank transfers, intrabank transfers by phone number, card limit settings, and more. The app was designed with a minimalistic UI and integrated various software development kits (SDKs) like I2C and IDWise to accelerate development.
Results: The app was launched as an early access program, boasting over 3,000 users. It has later become an in-house project, with the bank continuing to manage and expand its functionalities. The app also represents one of the first Flutter-based fintech solutions in the region.
3. A Banking Group’s 20% Increase in User Activity
[Source: Surf]
Challenge: A newly merged banking group needed a unified mobile app that would cater to customers of all five distinct banks. The project had a tight deadline for the first release, requiring adaptation of the bank’s processes and infrastructure to fit mobile development standards.
Solution: Surf helped the client transition to a mobile app by optimizing business requirements for mobile, adjusting backend processes, and addressing technical constraints. The team streamlined the UI design and supported the banking group in adapting business flows for mobile operations, such as QR code payments, online loan applications, and geolocation-based ATM searches. To ensure stability, 824 manual tests were conducted on payments, transfers, and product features before the app’s first release.
Results: The unified app led to a 20% increase in user activity, particularly in payments and transfers. Additional features like personalized offers, online chat, and a loyalty program further enhanced user engagement.
4. B2C Mobile Bank’s 70% Cost Reduction

Challenge: A B2C mobile bank struggled with poor authorization and registration issues, requesting a complete overhaul of its outdated native banking app. Additionally, the client wanted to implement test automation for faster bug fixes and quality maintenance, all within a large scope and tight development timeline.
Solution: Surf developed a new Flutter-based app with multiple authorization mechanisms. The app’s home screen provided an overview of all banking products, allowing users to hide unused items and access accounts, cards, loans, and deposits. The product enabled users to filter transaction history by type and date while featuring an expense analysis tool that breaks down spending by category.
Results: The app’s underlying Flutter framework enabled significantly accelerated development, entailing a 70% cost reduction for the bank's second app, which shares the same codebase.
