Testing & QA for a Crypto Portfolio Tracker

About project

Client

Our client for this project is a fast-growing Japanese fintech startup specializing in cryptocurrency portfolio management. They offer users a comprehensive mobile app to track, analyze, and manage digital assets, aiming to simplify crypto investing for a global audience.

Project overview

Let’s make your software quality its biggest asset.

Challenge

The client needed to ensure their crypto portfolio app could deliver accurate, real-time data despite the volatile nature of cryptocurrency markets. Even small errors in calculations or data display could destroy user trust and impact financial decisions.

The app also had to perform consistently across multiple mobile platforms and devices, which required thorough cross-platform regression and UX testing while still in development. This added complexity to an already tight schedule.

Finally, the client wanted an improved, user-friendly interface that would make complex market trends and transaction details easy to understand. Balancing accuracy, performance, and usability was a key challenge for the testing team.

Solutions

To address the challenge of delivering accurate, real-time cryptocurrency data, our team implemented thorough functional testing focused on verifying all calculations, data updates, and core app features. This ensured that portfolio values, profit calculations, and market fluctuations were displayed correctly and reliably under various conditions.

Given the need for consistency across multiple platforms, we conducted extensive regression testing and cross-platform testing on both iOS and Android devices. This helped identify inconsistencies and bugs introduced during development, ensuring the app’s performance remained stable and uniform across different screen sizes and operating systems.

To improve user experience and meet the client’s UI/UX goals, we performed detailed UX and UI testing, evaluating the intuitiveness of navigation, clarity of graphs, and accessibility of transaction histories. Our feedback enabled the client’s development team to optimize the interface, making complex crypto data easier to understand for users at all expertise levels. Throughout the project, continuous quality assurance practices and effective communication with the client ensured fast issue resolution and smooth progress toward a polished final product.

Testing types we used included:

• Security testing
• Functional testing
• Regression testing
• Cross-platform testing
• UI/UX testing
• Compatibility testing

Results

As a result of our focused QA efforts that lasted for three months, the client received a fully refactored, stable, and user-friendly mobile app that met all functional and usability requirements. The improved UI and optimized UX made it significantly easier for users to track assets, review transaction history, and follow market trends. With all critical bugs resolved and the app tested across a range of platforms and devices, the client was able to move forward confidently with the release, delivering a polished product to their growing user base.
