Mobile application testing services

Unbiased mobile testing for maximal user buy-in and fail-safe performance of your product

Our mobile application testing services

We provide comprehensive functional app testing services and mobile device testing across the USA and globally ensuring that your software shows stellar quality at all levels.

Compatibility testing

We assess your product compatibility with its target environments (devices, OSs, browsers) as well as operational guidelines imposed by app stores.

Functional testing

Our QA team runs mobile testing of your app against all of its functional requirements, from the interface to the mobile backend, to make sure the app behaves as expected.

Performance testing

We check system resources for weak spots and bottlenecks that may affect memory use, load resilience, and stability, rigorously testing performance at both the client- and server-sides.

Network connectivity

We test how the app performs under various network types, connection speed, and quality levels, including slow and interrupted connection.

Interrupt testing

Our online app testers evaluate how your app behaves when interrupted by other mobile apps and system events (incoming calls, charging, turning Bluetooth on/off, etc.)

Usability testing

Our experts identify usability issues through UX audit and testing to help businesses make the app as enjoyable and engaging for end users as possible.

Security testing

We run all-round vulnerability assessment and cybersecurity tests to assure your app protection and compliance with OWASP Mobile Top 10 and other standards.

How we choose devices for your app QA

To maximize the time- and cost-efficiency of your mobile app testing, we carefully select the most relevant devices, considering the software functionality, target audience, and industry specifics.

As a mobile software testing company, use our three-step approach:
  1. Requirements analysis

    • Formulate the needs and identify the target audience
    • Look into specific hardware and software features
  2. Review of the most popular devices in the region/world

    • Analyze market trends across multiple platforms
    • Collect statistics
  3. Selection of devices for testing

    • Define devices by their priority
    • Develop test roadmap, including automated testing probability

Frequently asked questions

Within their mobile testing scope, QA companies typically offer compatibility checks, functional validation, performance testing, network connectivity assessment, interrupt handling (e.g., incoming calls), usability testing, and security testing, with each activity is aimed at detecting different types of potential flaws.

Mobile app testing is performed by a dedicated QA team using both real devices and proven simulated devices to test apps. These specialists are typically well-versed in detecting performance bottlenecks, usability flaws, and security concerns in mobile apps and are often involved throughout their development.

Early detection of crashes, performance slowdowns, or OS-specific bugs helps teams fix them promptly before the app’s release, so it’s better to start testing as early in SDLC as possible. Continuous checks with each update also ensure that new features don’t conflict with the mobile app’s existing code.

Yes, within our CoE, we evaluate and adopt emerging testing technologies, tools, and methodologies, consolidate hands-on knowledge from real project experience into reusable best practices, and train and certify our mobile testing engineers to ensure they consistently deliver high-quality, user-centric solutions.

We rely on 180+ Android and 160+ iOS devices across a wide range of operating systems, screen sizes, and hardware configurations for accurate and reliable app performance validation.

Yes. Our QA team performs a detailed review of UI/UX compliance, navigation patterns, and adherence to platform-specific design and behavior expectations. They also check areas that often lead to app stores’ rejection, such as incorrect permission handling, unstable performance, crashes, incomplete features, and improper use of background services.

We use authentic devices from our fleet containing specified aspects, verifying the apps’ functionality, accuracy, permission management, and behavior under diverse real-world conditions such as low connectivity, sensor blocks, hardware bottlenecks, and others.

Yes, we automate testing for mobile products as part of our standard offering. This encompasses generating and managing automated test scripts for core operations, regression cycles, and vital customer workflows across multiple devices and environments. Testing automation is linked to CI/CD processes to facilitate fast, repeatable checks for every build, supplemented by manual testing for exploratory and usability goals.

Our specialists conduct upgrade and downgrade testing to ensure that the software installs successfully over previous versions without losing or corrupting files. They also verify older version support, API alterations, integration points, and regressions of core features.

Yes. We check screen reader compatibility, accurate tagging of UI elements, color visibility, flow, and usage habits to confirm the product is accessible to individuals with varying needs. We also verify apps’ adherence to universal design rules and platform-specific requirements, assisting in the creation of a welcoming experience across all hardware.
