Location affects network latency, CDN performance, legal compliance (GDPR, CCPA), currency formats, date/time display, and localization. Geolocation-based features (maps, search radius, geofencing) also behave differently. Covering a broad set of regions ensures reliable, compliant experiences for all global users.
Devices vary in hardware (CPU/GPU, memory), sensors (GPS, cameras, biometrics), input methods (touch, stylus, keyboard), and display size. These differences influence speed, rendering, gestures, and battery consumption. Real-device coverage prevents surprises that emulators often miss.
Browsers have different rendering engines, CSS/JS support, and performance quirks. Even the same browser on mobile vs desktop may differ. A well-defined browser/version grid helps prevent layout breaks and functional regressions.
Responsive designs and touch targets often break at specific breakpoints. Pixel density (DPI/PPI) and scaling can distort images, text, and controls. Testing key device classes avoids accessibility and usability issues for users across screen sizes.
Network speed, latency, jitter, and packet loss drastically affect app performance, streaming, sync, and error handling. Covering varying conditions ensures resilience in low-connectivity regions and highlights optimization opportunities like caching or graceful degradation.
Many performance issues appear only under constrained bandwidth. Simulating slow uploads/downloads helps validate timeout handling, compression strategies, retry logic, and progressive loading indicators for users with limited connectivity.
Accessibility testing ensures compliance (WCAG, ADA) and inclusive experiences. Different assistive technologies interpret semantics, focus order, and ARIA attributes differently. Early detection of barriers prevents costly redesign later.
Localization affects text expansion, truncation, fonts, date/time formats, and directionality. Certain languages expose encoding issues or text overflow in buttons. Locale testing also covers cultural calendars, currencies, and pluralization rules.
Payment flows differ in authentication (3-D Secure, OTP), redirects, regional compliance (PSD2), and refund rules. Testing diverse instruments validates checkout reliability, fraud detection, and currency conversions in all supported markets.
Apps often behave differently when databases grow or contain edge-case values. Testing against varied data conditions helps identify scalability, performance, and UI rendering issues.
Scheduling, logging, billing, and expiry features can fail when clocks shift or calendars vary. Covering time-sensitive scenarios avoids misfires in alerts, cron jobs, and international deadlines.
Environmental factors can alter device sensors, network range, or recognition accuracy. QA in realistic surroundings ensures dependable performance in the field.

We serve test environments
which represent your users
Test on devices which reflect your users
It's not cost effective to buy your own devices. The crowd has a multiple of devices across its 100,000 members, and we're able to find the perfect device for you. Test:
- Any device category from laptops to wearables
- Legacy devices still in active use
- Models from specific manufacturers, including Xiaomi
- Rare OS versions and niche configurations
- Region-specific device variants
- Hardware spec of integrated tech, e.g. headphones, camera
Test on representative versions and systems
Build a test on an older or dated version of your favourite OS. Understand how your user experience changes from a new high-speed iPhone to an older, data-limited device
- Older OS versions widely used
- Beta versions
- Region-specific software builds and forks
- Test an e-signature
- Test in low memory devices
Test the network conditions your
users really face
We can ensure that your product delivers reliably across the real-world connectivity scenarios your audience experiences every day.
- Different data setups
- Different internet speeds
- Low-bandwidth environments
- Local connections across bluetooth, laser or something else
- Congested urban mobile networks
- Public WiFi
Test across platforms and third-party integrations
- Embedded systems and IoT devices
- Cross-platform app experiences (iOS, Android, web)
- Third-party service integrations and APIs
- Connected hardware like wearables or payment terminals
- Smart home ecosystems and voice assistants
