Mobile App Development Review from Vasco Rouw
Weve been working with Kevych Solutions full-time for over a year, and the experience has been excellent. They handle the complete end-to-end development of our AI-powered mobile apps, including UI/UX, frontend and backend development, AI integrations, infrastructure, deployment, and ongoing support.
What stands out most is the extremely high level of their technical expertise and execution quality. They actively use AI and modern development workflows to maximize efficiency and deliver results quickly. The team is highly responsive, proactive, and always goes the extra mile to meet deadlines.
Since working together, we scaled from 0 to over 100,000 subscribers in just 8 months, and our apps are now generating more than $1M in monthly revenue. Whenever challenges came up, we solved them together efficiently, and Kevych Solutions continuously adapted and grew alongside our projects.
We highly recommend them to anyone looking for a reliable, high-level mobile app development partner.

Web Development Review from Anastasiia Cherednichenko
We worked with Stubbs on a project for a shared client. Our team was responsible for the web application layer, and they handled the blockchain backend. The integration points were clear and well-structured, which made our side of the work manageable. Communication was straightforward throughout, and we didn't run into any major blockers. There was a short alignment phase at the beginning where we had to figure out how the two parts would connect, but once that was sorted things moved without issues. Overall a solid team to work with on a technically split project like this.

Daria Mateichenko's Review Sourced from Google
We partnered with HS on few projects. Started with small test work to see how things would go on a small scale. During this test we were able to talk with mgmt team (both PM and Top mgmt), CTO and few tech team members and we liked what we heard. Team was really focused on suggesting to us different options and describing pros and cons of each. So we proceeded to a bigger project planning. It's mid the journey and so far we are happy with the approach and quality, especially when some tension comes up with bugs or anything - we're able to figure out the win win, and we receive reasonable outline of why this or that happened.

El porqué de las cosas's Review Sourced from Google
One of the worst software companies we’ve ever worked with.
If you're considering working with them, read this first:
They never delivered the product they committed to — after getting paid, they vanished, leaving us with nothing.
Their business model seems to be: drag out projects endlessly, then charge extra to fix their own technical mess.
Endless bugs — every fix introduced more problems. It was a never-ending cycle.
The product never worked at any point, not even partially.
They talk a lot about “best practices”, “scalability”, and “clean architecture”, but:
Their code, reviewed by external experts, was a disaster.
Functions with over 500 lines, no automated tests, no proper error handling, and no security.
Critical security flaws:
Users could access and modify other users’ resources — a massive breach of trust and privacy.
Ultimately, it was a complete waste of time, money, and energy.
When challenged, they were arrogant and even mocked us instead of taking accountability.
🔴 Avoid them at all costs. If you value your time, your budget, and your sanity — don’t even call them.

Steve Fecske's Review Sourced from Google
Internet Soft stepped in as my development team providing their team of programmers to my platform. They are a group of talented, skilled, and conscientious in everything they do, assigning the best people they have to the various types of technology I needed from UI/UX, php, API, and database. They adopted my platform as theirs and immersed themselves to learn the processes, concepts, and workflows needed to fulfill the promise of our platform's services. They apply their technical skills to understand and write the necessary algorithms. They work hard and diligently to get projects fully defined before undertaking, and then get it done on time. They test their work, present it to our marketing team, then tweak, then provide public testing, and only when ready, open full access to the target audience and advertising. They are well organized to execute our needs by providing a project manager and project leader who communicate with me as to what I want, select the right development talent, and then present it to them so they understand what is required. They have also given me direct access to the developers to further ensure they understand my vision and needs. I have enjoyed their hard work and we have endured the details. I look forward to the results, and proudly recommend Internet Soft for your technology.

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.
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.
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.
Special software testing services such as QA audit goes from $5,000 to $25,000.
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:
Core functionality issues: Use functional testing to verify features work as expected
Unstable code or new features: Use unit testing for individual components and integration testing for modules working together
Poor system stability after updates: Seek regression testing to make sure new changes didn't break existing features
Performance and load issues: Use performance and load testing to evaluate speed and scalability
Security issues: Security and penetration testing are commonly used across apps handling sensitive user data
Hard-to-navigate user experience (UX): Pursue usability testing to determine how intuitive the application is for end users
Low compatibility across devices: Compatibility testing can evaluate how good the app works on different browsers, devices, and OS versions
There is also the option to choose between manual and automated testing.
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.
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.
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.
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.
How do businesses measure the effectiveness of software testing?
The effectiveness of the software testing is measured via:
Code coverage: The percentage of the code that has been tested
Defect density: The number of defects found per unit of code
Test case effectiveness: The percentage of test cases that identify defects; helps prune redundant and ineffective tests
Time to detect and fix defects: The time it takes to identify and fix software defects and software bugs
Defect leakage: The number of bugs that "escaped" to production versus those caught during the testing phase
