What it is
Real device testing, explained
Simulators and device clouds are useful, but they don't reproduce real battery savers, real mobile networks, real accessibility settings or the habits of real users. TestLancer testers check your product on their own phones, tablets and computers, covering the browser and OS combinations you specify, and document every compatibility issue with evidence.
Who it's for
- Websites and web apps with mobile traffic
- Apps with a wide range of users
- E-commerce checkouts
- SaaS products used on many browsers
- Agencies signing off client builds
- Teams preparing a major launch

Real device testing: frequently asked questions
Which devices can you cover?
Testers use their own devices, which gives broad real-world coverage. Share your analytics or target devices and we'll match them as closely as possible.
Is this different from a device cloud?
Yes. Device clouds give you remote access to lab devices. We give you real people on their own devices, networks and settings, who also report what feels wrong, not just what's broken.
Can you test in specific countries?
We can request testers by country or region. Narrow locations may affect timelines and price.
Do you test desktop too?
Yes, including Windows and macOS across major browsers.
