On device testing
We have our own physical devices lab where our testing experts ensure your app is working exactly similar on different devices and screens. We have Apple devices, Android Mobile Devices & Tablets, MacBook, Windows PC, Linux PC, and more to ensure smooth execution of your app.
Automation testing
Automation Testing is one of the best methods to ensure that the newer app version does not hinder the existing functionality of the app or create a new bug. Automation Testing ensures that you are able to market your product in a lesser time with less risk of human error.
UI/UX testing
GUI of the app is the only presented part of the application that user interacts with and any errors in its design can result in serious consequences. Our UI testing services measure the performance and effectiveness of the UI by checking menus, buttons, forms, and other graphical elements to ensure they appear and work smoothly on standard devices and platforms.
User acceptance testing
In User Acceptance Testing, we put the app through actual user testing on multiple platforms and multiple cycles to measure the performance of app by capturing user actions in granular detail through tools which automatically takes screenshots and statistics so that the app can be calibrated in performance according to your expectation and real-world scenarios.
