Project Duration
3 months
Team Composition
2 Manual QAs
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.
