    Frequently Asked Questions

    Can you test my app on all devices?

    If we talk about real physical devices, unfortunately, no. Testing an app on every device model available in the market is not practical and expensive. However, we have a broad range of the most popular and widely used gadgets and unlimited virtual systems. This approach helps ensure that your app works well for your target audience.

    Can you handle large enterprise projects?

    Absolutely! Our testing company can manage testing requirements for large enterprises, including multiple app versions, complex integrations, and high-security demands. We can scale and customize our operations to ensure thorough testing and quality assurance.

    What tools are used for mobile app testing?

    We use automated testing tools like Selenium, device and browser simulation tool BrowserStack, and CI Jenkins. It helps us automate repetitive tasks, simulate various scenarios, and effectively manage and report on testing outcomes.

    Do I need to buy devices for you?

    You don't usually need to buy devices for our testing service. We have access to many devices through our labs and partnerships. If your app requires an uncommon device, you might need to provide it, but this is rare.
