Mobile App Development Review from Malik Boyd
Chop Dawg helped us turn our gifting app concept into a working prototype, handling wireframes, UI design, coding, data storage, and automation from scratch. Their team has been transparent, proactive, and highly responsive throughout the process. They provide clear schedules, flag issues early, and keep us informed at every stage. We’ve been very happy with the prototype so far and are excited to move into full iOS and Android development.

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.

Web Design Review from Anonymous
Chop Dawg supported us with UX/UI design for a new fintech web application. They took the time to understand our users, product requirements, features, and overall vision before moving into design. Over a 6 to 7 week engagement, their team shared regular Figma reviews, incorporated feedback quickly, and stayed highly responsive. They finished ahead of schedule with no budget issues, and the internal response to the final designs has been very positive. Their attention to detail, professionalism, and ability to keep the process organized made them very easy to work with.

Mobile App Development Review from Mica Palmer
They helped us solve issues. They designed an app for us.High level/quality of client attention and interaction. All communications, information exchages, and client servicing were well-conceived and well-executed. They kept me on my toes to provide them the information they needed from me. They kept excited about the project and, because of that, kept me optimistic and driving toward the success of my project.
The culture of coaching and support they provide start-ups. They don't sleep well unless they know you have all the tools and chops to obtain success. I've never seen any other company provide such rich and valuable deliverables along with ingenious and compassionate client support. Kodevent is a beacon of know-how and wisdom in an otherwise dark ocean for any start-up that is hoping for success.

We needed help designing the Frontend pages on my website. Also some design work.
Everyday I would assign my Frontend developer some key tasks and deliverables.
He would report back to me. An example of key deliverable he did was help design the logic of flow of grading when we have multiple types of questions. They were quick to respond and professional.
They had great professionalism, good talent, and good support.

Kodevent and their team were always great at communicating with our team. They worked very hard to finish tasks in the allotted time frame. When we had requests or changes, they were always quick to find a superior solution.
Our project is still ongoing, but they are waiting on our side of things to complete and go live. I am appreciative of their great communication skills.
They were always quick to respond and worked within our time frame.

During my tenure at Beaver Creek Resort Company I was tasked with building and launching a guest-facing app for the hundreds of thousands of visitors to Beaver Creek Mountain. I worked very closely with Quartus Technology and their team to meet the budget, the timeline and all the required features for the project. The app launched early! It's been an incredible success and the app has continued into phase 2 and 3 with added functions. I highly recommend Quartus Technology if you are in search of a quality app, strong development team and transparent pricing.

Mobile App Development Review from Chris Caputo, PMP
After looking at multiple vendors to build an app to provide information on municipalities we selected Quartus. The scope included the development of the app (including designs) and integration to a service that our development team created. Quartus was successful. They delivered in a timely, cost-efficient manner and were easy to work with. When we decided to have a second app created, we did not look elsewhere and stayed with Quartus. This app involved the development of a calculator to calculate and email title insurance premiums. Like our first app, Quartus had to develop the designs (they were able to leverage a portion of the work from our first app) and integrate to a different service that our development team created. Once again, Quartus delivered. These apps were for Android and iOS. They are a good partner.

Startups Software Development Review from Hector Castillo
We engaged with aTeam with the goals of designing and building a web app for out customers to monitor and control their IoT devices as well as an admin panel for our team to manage users and devices.
I was most impressed by the fact that aTeam did some initial work and wireframing during initial discussions which gave us confidence that aTeam has a solid understanding of our goals and vision before hiring them.
I think the main area of improvement is how QA and testing was done and the impact on our timeline. aTeam was good about delivering milestone deliverables on schedule, but there were often issues that would arise in our own testing that were not caught earlier in their testing, which would create additional work. I think impacts to our timeline could have been minimized if their testing had been more thorough and tailored to the user experience, and if expectations were made clearer at the beginning that, after the final milestone was delivered, there would still be an additional debugging period. Otherwise, aTeam was very good about sticking with issues until resolved.
Overall, I would be very happy and willing to work with aTeam again in the future and to refer them to others.

Mobile App Development Review from Anonymous
It’s been pretty cool using this app for handling all our company’s accounting stuff. You just snap pics or upload your receipts and docs right from your phone, which saves a ton of hassle. On the other side, the accounting team can grab everything they need from the web dashboard, so no more chasing papers or emails back and forth. It’s made tax time way less stressful, especially since it’s tailored for the UAE rules and all that. Plus, the folks behind it don’t just drop the app and disappear, they actually keep checking in, throwing out ideas, and sometimes pushing us to think differently. Communication’s been smooth, and they’re not just doing what you ask but really getting into the project. Definitely a game-changer for us.

We needed a fresh website that actually worked for us, something that could pull in new folks and keep our regulars in the loop without feeling like a hassle. These guys nailed it. The site looks great and runs super smooth, which honestly makes a big difference. Plus, they helped set up a way to grab emails from visitors, so we’re actually turning clicks into real leads now. They’re pretty chill to work with, always open to ideas and explaining stuff without the techy mumbo jumbo. Definitely made the whole process way less stressful than I expected.

The Wool Factory itself is an iconic landmark, blending historic character with contemporary architecture.
Its central location provides easy access to many of Charlottesville’s attractions, including historic buildings, museums, shops, restaurants, hotels, and the mall. WillowTree is an outstanding company to work for—they truly value their employees and provide a top-tier in-office experience.

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%
