We couldn't be more pleased with our experience with TouchZen. They took over a bad situation left behind by our previous development team and have been able to continue to build new features while cleaning up the old project. We have been very pleased with their developers responsiveness as well as the project management. I would highly recommend working with them for any of your web or mobile app development needs.

Mobile App Development Review from Dr Asa Frey
They worked on our app and continue to work on it to this day. We originally had a bad experience with various developers and ended up with a bunch of code and no functioning app - touchzen took the code and audited it and made it work and it work great now. Can't complain - still going to work with them and I would recommend to anyone who wants it done right.

Software Development Review from Vladimir Raykov
Perspecta Ltd provided exceptional server management and WordPress development services for our company. Their technical expertise was evident from day one, handling complex server configurations, security implementations, and WordPress customizations with remarkable skill.What truly set them apart was their outstanding responsiveness - consistently replying within 30 minutes, even outside business hours. Their communication was always clear and professional, translating technical concepts into understandable terms for our team.The project was delivered ahead of schedule with all deliverables exceeding expectations. Server performance has been flawless, and the WordPress implementation runs smoothly with excellent security measures in place.Their proactive approach to identifying and solving potential issues before they became problems demonstrated genuine partnership rather than just service provision. The team maintained transparent communication throughout, providing regular updates and detailed documentation.While minor improvements like more comprehensive initial project timelines would be beneficial, these are minimal considerations given the overall excellence of their work.I highly recommend Perspecta Ltd for any server management or WordPress development needs. Their combination of technical competence, rapid response times, and professional project management makes them an invaluable technology partner.

- Good work culture.- Healthy competition.- Co-founders aren't just our co-founders, they are moreover mentors.- Colleagues never let one another felt like colleagues. Friendship or I can say brotherhood is dominant.- Last but not the least, here developer word is not used instead we are called as engineer because here we get chance of learning and working on different frameworks, databases other than what we have mastered.

Frequently Asked Questions About Software Testing Companies
What services do software testing firms provide?
Software testing companies provide different testing services to identify errors, security risks, performance issues, and how the software behaves in real-life situations and across devices. As part of their software testing service, they also check if each feature works as expected, fix bugs, make improvements, and make sure new software development updates don’t break existing functions, so the software quality remains stable.Â
Hourly rates for QA testing range from $25 to $200+. The final cost is determined based on the size of the software or application, its complexity, required testing type, tech stack (custom-built and older legacy systems cost more), and niche. Â
The rate will also depend on the seniority of the software tester. Across the United States, junior quality assurance (QA) tester may charge $70 to $110 per hour, while the rate for a senior QA mentor and automation engineer can range from $130 to $200 per hour. Â
Special software testing services such as QA audit goes from $5,000 to $25,000.Â
How can businesses know what type of software testing do they need?
Businesses can determine what type of testing solutions they need based on the potential impact of failures and the likelihood of defects. Namely, if they encounter:Â Â
Core functionality issues: Use functional testing to verify features work as expectedÂ
Unstable code or new features: Use unit testing for individual components and integration testing for modules working togetherÂ
Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing featuresÂ
Performance and load issues: Use performance and load testing to evaluate speed and scalabilityÂ
Security issues: Security and penetration testing are commonly used across apps handling sensitive user dataÂ
Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end usersÂ
Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versionsÂ
There is also the option to choose between manual and automated testing. Â
Is automated testing more expensive than manual testing?
As an investment, automated testing is pricier than manual testing but offers a lower cost-per-test over time as it can run the same scripts repeatedly, without human intervention. Conversely, manual testing entails lower upfront fee, but its cost grows linearly as the project grows, as every test cycle requires paid hours from QA testers. Â
So, for short-term projects or ones with shifting requirements, manual testing is considered a more economical option, whereas for maintenance and regression cycles, automated testing grants better return on investment.Â
The main distinction between these methodologies is that manual testing relies on human observation and interaction to identify defects, whereas automated testing uses software scripts to compare outcomes against predicted results. Â
Manual testing is best suited for exploratory testing, usability assessments, ad-hoc bug hunting, and minor hotfix verifications where script development would be inefficient. Automated testing, on the other hand, is primarily used for regression testing to make sure the new code does not break existing features.Â
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:Â
Code coverage: The percentage of the code that has been testedÂ
Defect density: The number of defects found per unit of codeÂ
Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective testsÂ
Time to detect and fix defects: The time it takes to identify and fix software defects and software bugsÂ
Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase Â
