Specialized Mobile Gaming Performance Testing

MobileSlotTesting is a specialized division of Global App Testing, combining industry-leading QA expertise with deep focus on mobile slot performance since 2020.

Global App Testing has been the world's leading crowdtesting platform since 2013, trusted by hundreds of enterprise clients with 90,000+ professional testers across 190+ countries. But by 2019, the mobile gaming industry—particularly the iGaming and slots sector—had a problem that generalized testing couldn't solve.

Studios were launching beautifully designed slot games that failed within weeks. Not because of poor gameplay or unappealing graphics, but because players couldn't get past loading screens without their phones overheating, batteries draining in minutes, or apps crashing mid-spin. The industry was flying blind on performance metrics that actually mattered to players.

Traditional QA testing focused on functionality: does the game work? But mobile slot performance required something different—scientific measurement of load times, battery consumption, thermal behavior, and frame rate stability on real devices under controlled conditions.

"The mobile gaming industry needed what crash test ratings did for cars: a reliable, independent, scientific standard for performance."

In early 2020, Global App Testing assembled a specialized team from its pool of expert QA professionals to create MobileSlotTesting. Rather than build from scratch, we leveraged Global App Testing's decade of testing infrastructure, methodologies, and industry relationships—but focused exclusively on mobile gaming performance.

The mission was clear: bring scientific rigor and radical transparency to an industry that desperately needed objective benchmarks. No vague statements about performance being "acceptable." Just measurable, comparable, reliable data: Load time: 8.2 seconds. Battery drain: 12%/hour. Frame rate: 58 fps average. Thermal state: Nominal.

What made us different? We weren't developers trying to test their own games. We were specialized QA professionals with Global App Testing's backing, equipped with proper laboratory facilities, calibrated equipment, and ISO 17025 accreditation. We built a public database. Published our methodology. Made our standards transparent.

By the end of 2020, we'd tested 23 games. By mid-2021, we'd moved into a dedicated climate-controlled laboratory in Glasgow with full ISO 17025 accreditation. Today, we've tested over 500 games, helping studios benchmark against the market and fix performance issues before players discover them.

But our core principle hasn't changed: We're independent. We don't take investment from gaming companies, we don't soften results for big-name clients, and we test every game the same way—rigorously, transparently, scientifically.

When a player downloads your game, they're not thinking about your technical challenges. They're thinking: does this work? And you deserve to know the answer to that question before they do.

Part of the Global App Testing family: While MobileSlotTesting operates as an independent testing laboratory with its own team and facilities, we benefit from Global App Testing's infrastructure, quality management systems, and industry expertise—bringing the best of both worlds to mobile gaming performance testing.

Our Mission & Values

Three principles guide everything we do, from the way we calibrate equipment to how we report results.

🔬

Scientific Rigour

Every measurement traceable to international standards. Every methodology validated and peer-reviewed. No shortcuts, no assumptions, no "good enough."

🔓

Radical Transparency

Our methodology is public. Our data is public. Our uncertainties are public. If we can't explain how we got a number, we don't report it.

⚖️

True Independence

We don't take investment from gaming companies. We don't have preferred clients. A £249 test for an indie studio gets the same treatment as a £849 test for a multinational.
