Seamless user experience through passbrains crowdtesting

Passbrains managed crowdtesting & field validation services enable you to get your apps tested on all major device models, operating systems with representative user panels and testers with proven skills.

For each of your projects, we carefully select and engage testers from our global passbrains crowd with thousands of professional test engineers and tens of thousands user-testers. Selection criteria include skills, domain background, location, demographics, available devices, mobile subscriptions and many more parameters. For field validation activities, we engage test participants from your customer base, which we organize and managed in your exclusive private tester community.

Our project managers prepare test scenarios, user journeys, structured test cases and online surveys for each test. Our testers run exploratory and structured tests and deliver detailed reports on functional and usability issues, improvement suggestions, think-aloud video recordings and UX reports and ratings. All deliverables get carefully triaged, reviewed and validated by the passbrains team.

The passbrains platform provides you with dashboards and reports on project status, test results and comprehensive analytics and allows you to communicate with testers directly.
