AppSierra has done a great job and provided a highly professional QA service for our project. Team AppSierra works with pas-sion, is very dedicated, committed, has perfect communication skills and provides the best services to its clients. I would highly recommend to take advantage of AppSierra’s testing services!

Team AppSierra was incredibly responsive to my needs and had a deep technical understanding of what was required. We tried 3 other performance testing companies before coming across AppSierra. We’ll definitely be using their services again and will extend their scope of work, based on the success of this project.

AppSierra team is the most conscientious, well organized and productive developer group I have ever had the pleasure to work with. AppSierra truly has a talent for matching the best developer for a job, an extensive pool of enthusiastic, skilled and creative people to choose from.

I have been working together with AppSierra on a number of new releases. The AppSierra team has always provided us with prompt response, when it comes to the setup of the team, getting to know the contents of the new release package and reporting on the status. I would recommend working with AppSierra.

BrandAlley UK Limited has been trusting AppSierra for all its Manual Quality Assurance and Automation testing services. For the entire 2+ years of engagement and partnership, we have always been satisfied and impressed with the performance, dedication and quality of work shown by the 2 QA’s assigned to our account.

AppSierra team was a great support, customising their solution to our requirements, and providing everything on time. They have done extraordinary quality work on our test automation project, meeting strict deadlines. I’m happy to recommend them to companies who are looking for razor sharp and efficient teams.
