Built to serve teams that ship mobile, and mean it
Mobile Application Testers is the mobile quality practice of Kosansh Solutions Inc. We exist to make mobile quality failures predictable, preventable, and measurable.
Our mission
Quality your customers can feel on every tap
Mobile Application Testers is the mobile quality practice of Kosansh Solutions Inc., headquartered in Fort Worth, TX. We were established to address a structural gap in the market: mobile applications require a fundamentally different testing approach than web, and most QA providers do not specialise in it at the depth enterprise-grade mobile requires.
We structure and deliver engagements through a curated network of global delivery partners, including specialist mobile engineers, device lab operators, automation framework specialists, and in-country crowd testing providers. This model enables the delivery depth and geographic coverage that a single internal team cannot cost-effectively replicate, while maintaining consistent quality standards and accountability across every engagement.
Our approach is modelled on the rigour of professional services: clearly scoped engagements, defined deliverables, and quality metrics tied to outcomes your leadership team already tracks. Whether you are preparing for a major release, remediating a crash pattern, or embedding a continuous testing programme, we design the engagement to your operating context and your commercial objectives.
Why specialists matter
What we are, and what we are not
The mobile testing market is crowded with providers who offer coverage without expertise. Understanding the difference protects your decision.
Explore our servicesNot a device cloud subscription
Device access without testing expertise is just expensive infrastructure. We provide both: test architects who know how to build a matrix and what to find on it.
Not a generic QA body shop
Web QA methods applied to mobile miss the failure modes that matter: GPS sensor interactions, carrier network behaviour, biometric authentication edge cases, and hardware-specific rendering bugs. Mobile requires a mobile specialist.
Not a one-time audit
A single round of testing before a release creates a point-in-time snapshot. Our monitoring and synthetic journey services make quality a continuous signal, not a pre-release ritual.
Not volume over quality
Delivery resources are sourced globally based on expertise fit, not geography or headcount economics. In-country crowd testers are vetted through a rigorous proficiency process. Quality of output defines the programme.
Guiding principles
Four principles that shape every engagement
These are operational commitments that determine how we scope work, build test matrices, and measure success.
Root cause over symptom
A crash report tells you something broke. We find the device-OS-keyboard-network combination that caused it, and provide the reproduction path that makes the fix hold across every configuration in your user base, not just the one the developer tested on.
Coverage where your users actually are
The device matrix is weighted by your analytics, not industry averages. Low-memory mid-tier Android accounts for 60%+ of global installs. We test there, not just on flagships, because that is where most of your users' experience is shaped.
Quality is a business metric
Crash-free sessions, checkout success rate, and app store rating are revenue metrics, not engineering vanity metrics. We connect test coverage to the numbers your leadership team tracks, and scope every engagement to move those numbers.
Compliance is not optional
App Store rejections, PCI DSS findings, and HIPAA gaps are preventable with the right pre-release coverage. We build compliance validation into every engagement from day one, so the first time a QSA or App Review team sees your app, it passes.
Global delivery through a curated partner network
Mobile quality at scale requires depth in multiple specialisms simultaneously: device lab access, test automation expertise, in-country human testers, security assessment, and CI/CD integration. We bring these capabilities together through a structured network of delivery partners rather than a single in-house team.
Crowd testers in our network are vetted through a technical proficiency process, domain knowledge assessment, and a supervised pilot cycle before being accepted onto client engagements. Delivery leads provide single-point accountability on every engagement.
In-country testing is particularly valuable for localisation edge cases, network-condition-specific failures, and carrier-specific billing and payment flows that cannot be replicated in a lab environment.
