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.

I had an excellent experience working with this engineering firm to build a React Native app. Oleg and Ihor were exceptional software engineerstheir technical skills were top-notch, and they consistently delivered clean, well-structured code on time.
What really set this team apart was Volodymyr, their CTO. He was incredibly hands-on, maintaining clear and frequent communication throughout the project. He was always responsive and proactive in managing the work, which made the entire process smooth and stress-free.
The team was professional, reliable, and genuinely committed to quality. They understood my requirements and provided valuable input that improved the final product. Highly recommend this firm for anyone seeking skilled developers and excellent project management!

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.

The solution provided by the Spiral Mantra team involved creating a data identity to identify and extract the right data when needed using DDL; this made it easier for the data team to extract data much faster when needed.
The solution improved decision making with reports that are formed with processed data. This has not only improved their overall loan management system but has created a sustainable and future-proof pipeline of data.

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.

We spoke to a few different companies as we set out to find someone to create a website/database application to augment our desktop software. We chose The Demski Group in part because we found them very easy to talk to in our interview. That first impression stuck as we have a great relationship with them now. We are currently planning to farm out another project and are not even considering looking for anyone else to take it on.

What services does a software testing company provide for your business in the United States?
They provide a comprehensive range of services designed to validate and improve software quality through systematic evaluation and advanced tooling.
Core testing services include:
Quality assurance and testing strategy: Audits software and defines testing scope, priorities, coverage, approach, and reporting.
Functional testing: Verifies that software features work according to specified business and functional requirements.
Regression testing: Detects unintended issues introduced by system changes and releases.
Performance and load testing: Measures the application’s reliability and responsiveness during peak usage.
Security testing: Identifies and resolves security vulnerabilities and tests against compliance and governance requirements.
Usability testing: Assesses user experience, interface intuitiveness, and overall accessibility of the solution.
Integration and API testing: Validates how different system components and third-party services work together.
In addition to these services, software testing companies implement a mix of manual (often for exploratory and user experience-focused scenarios) and automated (repeatable checks throughout the development cycle for speed and consistency) testing models.
How much does software testing cost?
Software testing costs about 15%-25% of the development costs or 23% of the IT budget. In terms of hourly rates, US software testing companies charge an average of $100-$250 per hour, with more complex systems or specialized tests going beyond $300/hour.
The final rate will depend on solution complexity, testing coverage, quality requirements, project timeline, and current technical debt.
Here’s how much software testing costs as a percentage of the software development budget:
Critical systems and highly regulated industries: 40%-50%
Enterprise applications: 25%-35%
Consumer-facing applications: 15%-25%
Mobile applications: 20%-30%
In practice, basic one-time testing projects, such as a website penetration test, cost approximately $5,000-$10,000.
On the other hand, continuously evolving software solutions that require regular comprehensive testing can fetch between $20,000 and $70,000+ per month.
Are there any additional costs to consider when working with US software testing agencies?
Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA:
Tooling and platform fees: Software license or subscription fees for device farms, performance testing platforms, and security scanning tools may be billed separately from the company’s overall rates.
Device/browser lab coverage: For tests that require broad compatibility coverage, costs can increase based on access to real devices, operating system versions, and browsers.
Scope growth: New testing requirements, additional integrations, new platforms (mobile/web), or expanding acceptance criteria often require a change order.
Additional test cycles: Extra rounds of re-testing and regression tests beyond what’s defined in the service level agreement (SLA) incur additional costs.
Defect remediation effort: Fixing defects is often outside the testing scope and is billed as an additional engineering or development fee.
Compliance and security deliverables: If you require additional formal evidence (e.g., audit artefacts and traceability) or expanded security testing, expect incremental charges.
How long does software testing usually take?
On average, software testing takes around 20%-40% of the total software development time. However, the final timeline will depend on infrastructure complexity, test scope and methodology, and quality requirements.
Here’s an approximate software testing timeframe based on the typical software project schedules:
Full Release Schedule
Software Testing Timeframe
Small software builds (e.g., Landing platforms)
12-24 weeks
2-4 weeks
Mid-sized builds (e.g., Fully customized mobile apps)
16-40 weeks
3-4 months
Large builds (e.g., Multi-module platforms)
36-144 weeks
6-12 months
Notably, software testing is often integrated into the software development lifecycle (SDLC). As such, it’s common to see QA and testing done in 1-2-week sprints rather than a separate stage altogether.
What industries do US software testing firms typically work with?
US software testing providers work with a wide range of industries, as all digital solutions need to be tested in some capacity. However, these are the sectors that quality assurance (QA) and testing experts work in based on the State of Testing Report 2025:
Tech: 35.2%
Finance and insurance: 16.9%
Others: 12.7%
Healthcare: 10.9%
Business and information: 4.5%
Retail: 4.1%
Marketing: 3.7%
Transportation: 3%
Government: 3%
Gaming: 2.6%
Education: 1.9%
