Admios Reviews & Testimonials
Will McDonald
VP Product at Conductor
5.0★
Web Development Review from Will McDonald
I was able to dictate requirements at a high level without having to deal with the details. The Admios team was able to make technical level decisions on their own. They were a first class partner of the team.
Mark Griffin
Director of Engineering at Latent AI
4.8★
Software Development Review from Mark Griffin
Due to past experiences, Latent AI is always cautious when hiring external engineering resources for a project. But collaborating with Admios is a breath of fresh air. The agencys account manager is nothing short of professional, attentive, and understanding of client needs. Furthermore, Admios seasoned and self-sufficient engineers fit seamlessly into the Latent AI culture. The team treats and trusts them as one of their own. (Verified via email)
Matt Attaway
VP, Software Engineering at Off the Grid
4.7★
Mobile App Development Review from Matt Attaway
Off the Grid has had a longstanding developer partnership with Admios. Recently, the client trusted Admios with building a complex React Native POS system and a guest order-ahead app. Given the complexities of the project, Off the Grid wouldn't have chosen any other agency to work with. The Admios' developers did an excellent job, the management was proactive, and the software quality is exceptional. Admios is highly recommended. (Verified via email)

Caring Gene's Review Sourced from Google
Troy Web took over the maintenance and service contract for our in depth healthcare career information and job posting website. Their ability to seamlessly take ownership, clean up and bring our site into a stable wordpress environment was done not only quickly, but also flawlessly. During our time with Troy Web, a number of updates and additional features were required to be built. They were not only able to build these aspects, but also to correct past build issues in the process making the site more reliable on a daily basis. In the last 6 months of their service we didn’t experience any unforeseen downtime with our website, which is extremely important to the function of our site for those that access and use it on a daily basis. Troy Web provides an exceptional service with a team that is always available and very knowledgeable.

I had the pleasure of working with Colchuck Consulting on my organization's website and their expertise and customer service exceeded all expectations. They assisted me from initial conception all the way through our website launch, with an eye for detail. They helped me take my ideas and transformed them into a well-designed, user-friendly website that not only looks fantastic but also functions seamlessly. Additionally, their ongoing support and willingness to make adjustments along the way have been invaluable. As an entrepreneur starting a new project, working with them has been so helpful. I wholeheartedly recommend Colchuck Consulting to anyone in need of top-notch web-design, or custom technology solutions.

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