Mobile App Development Review from Karan Magu
It's been an absolute pleasure to work with Sunny and his team at Quokka these past couple of years on myweb - an interface for organizing personal digital activity. Couldn't have chosen a better technical partner to bring my vision to life. This compact yet extremely capable team are the ones who transformed a mere sketch on a piece of paper into a proper and performant software, which I would say works as well as any global software you may have installed on your device (often created by large venture funded team of engineers). I found Sunny after having a poor experience with the quality produced by a previous software development firm, and was instantly convinced by his professionalism and intelligence. I've worked with the team across multiple domains - whether it's iOS Swift and working on a complex share extension for iphones, or Kotlin for Android, or backend work for syncing data, or making a desktop client, even UI/UX design - and would wholeheartedly recommend them to anyone looking for a transparent, trustworthy and capable young team in the realm of software dev. One thing I really appreciated is the regular updates and check ins from their end at each step of the journey, which keeps things clear and transparent.

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
Core services include:Â
- Functional testing Â
- Performance testing Â
- Security testing Â
- Usability testing Â
- Regression testing Â
- Automation testing Â
- Accessibility testing  Â
- Mobile app testing Â
- API testing Â
- Compatibility testing across devices/browsers Â
- Compliance testing Â
- Testing with artificial intelligence (AI) tools
- QA auditÂ
How much do software testing services cost?
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
