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 Dennis Temko
Dreamers was the only firm capable of building my ambitious vision for HyperCite. They transformed an unprecedented concept into a patented, production-grade legal technology platform designed for fact-checking. This included help in product strategy, and leading UX, algorithm development, AI, database and cloud architecture, frontend and backend engineering, scalability, observability, CI/CD, deployment, and ongoing maintenance. They delivered two California product versions and a dedicated Arizona implementation integrated directly with the appellate court, where HyperCite has operated for more than five years. Today, HyperCite not only automates hyperlinks between legal briefs and cited records; its AI fact-checking system compares claims against supporting evidence, flags contradictions and unsupported assertions, and takes judges and attorneys directly to the underlying source. The result is faster, clearer, and more reliable judicial review, delivered through close collaboration with HyperCite’s leadership and the Arizona court CIO.

Sito Pons's Review Sourced from Google
We just wrapped up a several-month project with the team at Kodexo Labs Austin and they were fantastic to work with. The project was complex, but they stayed patient, responsive, and super professional the whole time. Their team made everything feel smooth and well-organized, and the end result really speaks for itself. Definitely one of the best software development companies in Austin and we're already planning our next project with them.
Sean Peterson's Review Sourced from Google
Worked with Kodexo Labs Austin on a custom app for our delivery service, and they really impressed me. We wanted to integrate some AI features to predict delivery times and optimize routes they not only made it happen, but explained the tech in a way that actually made sense. Communication was smooth, no BS, and they stuck to the timeline. If you need mobile app development in Austin, especially anything AI-related, I’d definitely recommend them.
Georgia Andrama's Review Sourced from Google
My project was complex, I knew that going in. But what truly amazed me was how Kodexo Labs tackled the challenges in my idea and brought it to life with precision and creativity. I deeply trust Kodexo Labs as a top-tier custom software development company in Austin. Working with their team has been an outstanding experience. Highly recommended.

We recently worked with Geeks to do a scoping workshops/Solution Design for the development of a application for streamlining our reporting and surveying processes.The process from opening meeting to final wireframing was seamless. The knowledge and approach of the Business Analysts and the whole team were excellent, they listened, advised and offered thoughtful suggestions for improvements.The end specification for the application met and in many ways exceeded my expectations.Professional, friendly and smart. Great experience
Bradley Ebsworth-Willis's Review Sourced from Google
We recently completed a solution design project with Geeks, and I can not speak highly enough about the service we received. Geeks really are experts are making the complex appear (relatively) simple. Through a thorough and detailed solution design process, we created a prototype product that met all of our requirements. Geeks focus on producing visual representations of the product you are seeking - which is a far more efficient and helpful way of solution designing (as opposed to a written specification). Thank you very much for your support once again and I look forward to working together again in the future! Bradley (Associate Director)

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:
