Which providers offer the most extensive real device testing labs for global app testing?

I’m looking for recommendations on real device testing platforms that give access to a large variety of physical devices spread across different regions. Our goal is to test apps (both mobile and web) on actual hardware rather than emulators, so we can catch device‑specific issues before release.

I’m especially interested in solutions that:

  • Provide a wide range of real devices (different manufacturers, OS versions, screen sizes)
  • Are available in multiple geographic regions
  • Integrate with CI/CD workflows or automated test suites
  • Offer reliable performance and accurate reporting

Have you used any real device testing services that stood out, especially in terms of coverage and reliability? I’d love to hear your experiences!

Real device testing ensures apps work across diverse hardware, OS versions, and screen sizes. Candidates might mention platforms like Perfecto, AWS Device Farm, and Kobiton, which offer hundreds of real devices worldwide. Explaining why real devices reveal hardware-specific bugs better than emulators shows practical insight.

Geographic coverage matters for global testing. Candidates should discuss latency, regional device availability, and network simulations. Highlighting how global labs help test app performance and behavior under various conditions demonstrates awareness of enterprise-level testing challenges.

Integration and reporting are essential. Candidates could explain how these platforms work with CI/CD pipelines, provide actionable logs, and automate test execution across multiple devices simultaneously. Detailing these practices shows the ability to manage large-scale test coverage efficiently.
