By integrating Firebase, we can optimize user engagement, monitor performance, and make data-driven decisions to continually enhance the app's functionality and overall user experience.

This diverse and powerful set of tools allows our teams to work in harmony, propelling the successful development, evolution, and maintenance of Tinka's innovative mobile application.

Key features and functionalities

The Tinka mobile app offers a diverse range of user-friendly functionalities, designed to streamline access to Consumer Credit, Spread Payment, and Buy-Now Pay-Later financial products . This fintech mobile app simplifies the process of purchasing online loan products for Tinka's customers.

One of the app's key features is passwordless login, allowing users to access financial products without the hassle of remembering passwords. Instead, users receive a one-time code or link via email after entering their email address, which they can use to log in.

Tinka provides easy access to consumer credit, enabling users to receive funds directly through the app without waiting in long bank queues. The company also offers a physical credit card for versatile in-store (offline) payments. However, the most popular feature is the Buy Now - Pay Later (BNPL) option, which allows users to purchase items and choose a later date to pay or spread payments over several months. Users can also choose from various credit products, payment arrangements, or loans that best suit their needs.


Security is paramount, with biometric security, credit risk calculation, and fraud prevention measures in place. Users can also access Tinka's in-app chat support for assistance.

Account management features ensure users stay informed, with optional push notifications providing updates. The app also implements the latest standard in KYC (Know Your Customer) processes, utilizing iDIN for advanced identity verification. With these comprehensive features, the Tinka app offers a seamless and secure experience for customers seeking flexible financial solutions.

Duration, milestones and team

Our collaboration with Tinka began in 2019, with an initial project delivery timeline of six months. To ensure an efficient and flexible development process, we adopted the Agile Scrum methodology, working in 200-hour sprints.

The initial team consisted of 2 senior Flutter developers, who were responsible for crafting the app's core functionality and user experience. Over the years, we have delivered more than 8,000 hours of development work, continually refining and expanding the app's features.

Throughout our collaboration with Tinka, we have consistently adapted to their evolving needs by scaling the team up or down as required. This flexible approach optimizes Tinka's costs, ensuring that resources are allocated efficiently and effectively. By maintaining this level of adaptability, we can provide the necessary support and expertise for the ongoing development and success of Tinka's innovative mobile application.


In early 2022, a senior backend developer joined the team, focusing on AWS CDK to develop essential backend microservices that support and enhance the app's capabilities. With this expanded team, we continue to work closely with Tinka, ensuring the ongoing success and growth of their innovative mobile application.

As the Tinka app has become the primary driver for consumer reach, there are plans to scale up both the Flutter and Backend teams to accommodate the increasing demand for new features and enhancements. Additionally, we will allocate a full-time QA engineer dedicated to writing a comprehensive set of end-to-end automated tests. This expansion will ensure the app maintains its high quality and continues to meet the evolving needs of Tinka's growing customer base.
