REAL DEVICE CLOUD
Do not trust an emulator
Run live and automated app tests on the exact device, OS, locale, and carrier your users actually use.
Test on a real device freeTap, swipe, pinch, zoom, rotate, and multi-touch, tested exactly as your users perform them. Every interaction runs on real hardware your users actually hold.
Test in real scenarios where camera, GPS, face ID, touch ID, fingerprint recognition, all behave exactly as they would in your user’s hands, not simulated inputs.
Identify crashes, trace network requests, and inspect layouts without leaving the dashboard or losing your session context.
KANE AI
AI-native test automation with KaneAI
Upload your app, describe the test, and KaneAI writes it, runs and it and self-heals, if required.
Run your first real device testNo Appium, no scripting knowledge required. Describe your test scenario like "Test Face ID login on iPhone 17 under 4G throttle" and KaneAI converts it into a running automated test on a real device.
When a UI element changes - a button renamed, a field repositioned; TestMu AI Real Device Cloud automatically updates the locator and keeps the test running.
No separate configuration, no device setup. Parallel tests run on real iOS and Android hardware in seconds, with full video recording, device logs, and network traces attached to every run.
HYPEREXECUTE

Do parallel testing with TestMu AI's HyperExecute. Same tests, same pipeline, your feedback loop shrinks by up to 70%.
Run parallel testsDistribute your test suite across up to 100 real device-OS combinations simultaneously instead of sequentially with no pipeline changes.
Compatible with Appium, XCUITest, Espresso, and Detox. One configuration file change is all it takes to switch with no rewrites and no lost test history.
Native 50+ CI/CD integrations with GitHub Actions, Jenkins, CircleCI, GitLab CI, Azure DevOps, and Bitbucket Pipelines.

Test Hardware Level App Behaviour
Test the sensors and OS behaviours emulators cannot fake: network throttling, biometrics, GPS, video, and background interruptions on real devices.
Throttle network speed on real devices to simulate 3G, 4G, 5G, or offline conditions across live and automated sessions.
Get accurate results for motion-sensitive features and orientation-based UI using real accelerometer, gyroscope, and barometer sensors.
Run extended streaming sessions, on real iOS and Android hardware to validate video quality, syncing, layout, buffer time, and more, all from your browser.
Check accessibility testing on real iOS and Android devices including dynamic text sizing, high-contrast mode, colour inversion, reduced motion, display zoom, and assistive touch.
Locate elements, debug layouts, verify accessibility, and inspect app state directly on real iOS and Android hardware with built-in Appium Inspector and native DevTools.
Set a device's location to any country to test for localized pricing or currency display, regional push notifications or offers, and beyond.
Switch between apps, simulate calls, lock the screen, and test how your app survives real interruptions, OS memory reclamation, and multi-tasking transitions.
Plug into TestMu AI's Real Device Cloud
Point your Appium, XCUITest, Espresso, Detox, or Maestro suite at our cloud with one endpoint change. No rewrites, no migration.

@nrambeck
86000 + Minutes & 1300 + Tests Thank you for helping us to tackle client requirement of running automated tests in multiple mobile browsers. With this, we had the flexibility to run multiple tests in parallel and our tests became scalable by widening the test coverage and reducing the time of execution. We highly recommend TestMu AI if you are looking for a cost-effective method to scale your tests, Thanks again and we are looking forward to leverage this to other projects as well.

Frequently asked questions
A real device cloud is a remote infrastructure of physical devices hosted in a data centre, accessible via a browser or API. Unlike emulators, real device clouds reproduce exact hardware behavior allowing teams to test mobile apps under production-equivalent conditions without owning or maintaining physical devices.
Emulators and simulators approximate device behavior using software on your laptop. They are fast and low-cost but cannot replicate hardware GPU decoding, real battery drain, thermal throttling, Widevine L1 DRM, biometric authentication via secure enclaves, or real cellular network conditions. Real device cloud testing runs on physical hardware, catching the bugs emulators miss before they reach production.
TestMu AI offers free real device testing every month, no credit card required. Sign up, pick a real Android phone or iPhone from the dashboard, install your app from a public URL, store, or local upload, and start a live device session. The same free tier covers automated Appium, XCUITest, Espresso, and Detox runs against the real device cloud.
Emulators run a virtualized OS image on top of your laptop's CPU. They are excellent for fast unit-level checks, but they cannot reproduce real GPU rendering, real cellular behavior, biometric prompts, push notification scheduling, thermal throttling, battery drain, or hardware sensor input. For release-grade confidence, you have to validate the build on the same silicon your users hold.
Both platforms offer real device clouds, but TestMu AI differentiates on three dimensions: KaneAI writes and maintains Appium tests from plain English (no scripting required), self-healing tests automatically repair broken selectors when UI changes, and pricing starts at $15/month versus others' $39/month. TestMu AI also offers 10,000+ devices versus others' 3,000+, and geolocation support across 170+ countries.
