Chop Dawg took our iOS app from concept to launch, handling design, development, AWS, and App Store requirements. Their team was responsive, practical, and highly supportive throughout the process. They also stayed involved after launch with updates and fixes, and even helped promote the app through their network. Their support contributed to strong early growth and helped position the company for a later acquisition.

Mobile App Development Review from Guiulianna Cespedes
Our company needed an Android app that could support a mental health platform in a way that felt calm, easy to use, and dependable for daily users. We hired Simpalm to build that product in Kotlin and help us move from concept into something real customers could use. For us, trust and simplicity mattered more than packing in too many features.They took a fairly hands-on role, which was helpful because we were still making product decisions as the project moved. Some weeks I was deeply involved reviewing screens, and other weeks they pushed things forward on their own. That balance worked well. They would usually come back with two or three options instead of just asking what we wanted.We did hit one rough patch around notifications where the first version didn’t behave the way we expected, so that had to be revisited. They fixed it without making the process difficult.The finished app runs smoothly, feels organized, and gave us a much stronger mobile presence on Android. Most importantly, early users found it approachable rather than overwhelming, which was exactly what we wanted.
Mobile App Development Review from Amanda Chalofsky
My experience with Simpalm was very good. They made a full prototype of our neuro-wellness app so we could show partners and investors what our system looks like. It matched our brand and showed the flow in a simple way. Their communication was steady, they stayed on time, and they explained things clearly. The prototype helped people understand our idea fast, and it moved our project forward. I felt supported the whole time.
Mobile App Development Review from Matt Rudnick
Working with Simpalm has been a really positive experience. We hired them to handle the frontend development of our mobile app for iOS and Android, while our backend was already in place. From the start, their team communicated clearly, stayed organized, and met every deadline we set. They were flexible when we added new features, and their designer’s input really helped improve the look and usability of the app. I appreciated how reliable and easy they were to work with having a U.S.-based team made communication smooth and fast.

Software Development Review from Sidharth Dugar
We worked with Techstack to develop a digital platform that could support the financial and operational needs of our growing client base. Our vision was to create an integrated web solution that would bring together financial management, client communication, and digital infrastructure into one cohesive system. The goal was to give small and medium-sized businesses the same level of data visibility and workflow efficiency that large enterprises enjoy but through a user-friendly, scalable product.Techstack company quickly understood what we were trying to achieve. They built a modern web application architecture that unified financial analytics, project tracking, and CRM capabilities while ensuring top performance and security. Their team handled everything from backend development to UX optimization.What stood out most was how seamlessly Techstacks team balanced precision with flexibility. We had tight deadlines and evolving priorities, yet they consistently delivered on time without compromising quality. Communication was clear and proactive, we always felt aligned, even as the project evolved.The result was a platform that allowed us to operate more efficiently and deliver a better experience to our clients. It centralized our data, reduced manual processes, and helped us scale faster without adding unnecessary complexity. Techstack brought strong technical expertise and a genuine sense of ownership to the project, turning a challenging concept into a powerful business tool that continues to grow with us.
Web Development Review from Sri Sharma
When we brought Techstack on board, our analytics subsystem was at a breaking point. Performance issues, data inconsistencies, and outdated architecture were slowing us down and creating friction for both our internal teams and end users. Given the scale of our platform: millions of customer interactions generating terabytes of data daily we needed a partner who could not only fix the flaws but also future-proof the entire system.Techstack company took on the challenge with impressive precision. Their team started with a deep audit that revealed critical weaknesses in our existing infrastructure. From there, they restructured the backend, optimized performance, and built a reliable synchronization flow between our internal tools and third-party CRMs. Techstack introduced a new architecture powered by Amazon Redshift and an asynchronous analytics engine, which dramatically reduced data retrieval times and improved responsiveness across the board.What we appreciated most was how seamlessly they integrated into our process. They communicated clearly, delivered consistently, and made sure every change was fully tested and stable before rollout. The results were: system reliability improved, performance bottlenecks disappeared, and we could finally handle large-scale data processing without worrying about stability. Techstack company combined strong engineering skills with a genuine commitment to understanding our goals. They helped us rebuild confidence in our platforms ability to scale and perform at its best.

Our team can easily log into the CMS and update case studies without needing a web developer, which has been a huge advantage. Our primary concern was the seamless conversion of our old templates, and RichestSoft handled this flawlessly.

Flutter Development Review from Undisclosed
The company has a salesman who overpromised, but once the project started, he was never found to address the underdeliver. Since the first brief, I made clear our products two main selling points. Two years after, I have had to learn some code to look under the hood and discover a half-baked and improvised "solution". Now, I ended up with an incomplete product that fails to deliver the two main functions I requested (and was promised). On top of that, there is a lack of order in terms of naming, cleanliness, and hierarchy. I cant recommend them.

Throughout the seminars, Upcore Technologies fostered multiple open talks to ensure that they thoroughly understood our unique objectives. The end product was a well constructed proposal that specified practical AI solutions. The major milestones and strategic roadmap delivered clear, measurable results that demonstrated considerable progress toward our objectives. They stuck to the timetable, completing each milestone on time. Their attentiveness to our demands was particularly notable; they were always ready to answer any questions or concerns, ensuring that communication flowed smoothly throughout the project. Upcore Technologies' ability to simplify difficult AI concepts was particularly impressive. They presented these concepts well to both our business and technical departments. Furthermore, their collaborative approach and commitment to fully understanding our specific needs set them apart from other organizations with whom we have previously partnered.
Generative AI Review from Nigel Bannister
The major aim was to develop an AI-powered health bot that could analyze market data independently, find health opportunities, and execute medical analysis with precision. To accomplish this, key deliverables included the creation of a sophisticated AI-powered health bot, the integration of machine learning and natural language processing (NLP) technologies, real-time market trend analysis and decision-making capabilities, and extensive testing and optimization to ensure maximum returns while minimizing risks. Upcore Technologies delivered an advanced AI health bot that used machine learning and NLP to analyze real-time trends and historical data, interpret news and market signals to make informed medical decisions, execute medical issues with remarkable speed and accuracy, and demonstrate significant improvements in our health performance and management.
Mobile App Development Review from Rory Bordiuk
Upcore's team displayed a thorough comprehension of our project's vision and objectives right away. They spent a large amount of time debating every aspect, which was critical in determining the project's path. Their persistent engagement throughout the discovery process, final release, and beyond was quite comforting. Upcore Technologies excelled at taking our ideas and transforming them into mock-ups, color schemes, and layouts. They were careful and diligent, ensuring that every aspect was consistent with our concept. The final design exceeded our expectations and demonstrated their commitment to excellence. The app has gotten incredibly good reaction, with many other businesses adopting and promoting it. Even before the formal introduction, the notion sparked interest.

Mobile App Development Review from MohamedAH Ouedraogo
My experience with Xtrem design house and downtown applications was worse. Adam knight, Randoph, Micheal and Dudley drove me crazy. Three projects, one a delivery application, second a bill payment application(not even the alpha version done)and an online academy. $11000, $6000 and $4500. None was done from January 2021 to December 2022. I did not get any money back from them except the files. Adan knight continued to ask for money and gave arguments that the unique developer had his daughter sick. The backend was a mess. I filled claims against them but they never responded to the better business bureau .com. The result is now I am seeing the follow of my application same as someone else application. They were nice until they started wrong things. I am fighting actually to correct these projects. Just be careful with them and dont let them fool you with the nice things. My project PORTER had to be rebranded because even 3 months work Micheal to run the SEO, they agreed to the name PORTER, but there was a company in India with THE PORTER has a trademark. That company sent a note to change the name but Adam knight kept it and gave it to me 2 months later. The painful is the bill payment app. We started the project in December 2021. To November 2022 we were at the alpha version with a payment of $6000 done.
Mobile App Development Review from Karen Stearns
Adam and the team at Downtown Applications have been great to work with. They are knowledgeable and quick to respond to all needs and requests. The overall cost for the mobile app project was reasonable, especially considering the amount of work and skill required. The Downtown design team does and excellent job at creating and building a brand that will stand out. If you're looking to achieve positive results we would recommend the team at Downtown Applications.
Mobile App Development Review from Damahn Miller
A good company that I will recommend to anyone that has any questions or needs with any business opportunity questions. The whole team is great but Adam and Randolph are the best.

Always calling with plans and ideas that I love and they never play with your money. Great princess!!!!! We achieved so much already and Im thankful

The company was taking over from another software company, and it was a lot of work for them to initially understand what they were taking on. The communication was great if I wasn’t happy about something, they would always try and do something to ensure they delivered exactly what I wanted. Sometimes when you are spending your own money, it’s hard to not have the scope creep they hold you accountable to ensure success. I would definitely work with Moby again.

Common mistakes include:
When asked about the most significant challenges to automated software testing deployment, struggles with implementation (36%), automation skill gaps (34%), and high upfront costs (34%) were among the most commonly reported.
Per the State of Testing Report, these are the most common metrics businesses are using to measure a software testing team’s effectiveness:
Rated 4.8 on Google and 4.7 on Trustpilot, DesignRush Agency Directory is a reliable resource for finding software testing companies in the United States. We owe this to our executive selection team, which follows a strict screening process when featuring agencies on the platform, assessing key performance indicators, like portfolio, client reviews, and industry reputation.

They provide a comprehensive range of services designed to validate and improve software quality through systematic evaluation and advanced tooling.
Core testing services include:
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.
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:
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.
Beyond project scope, complexity, and timeline, these are additional costs to consider when working with software testing agencies in the USA:
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 | 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.
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:
