Real Robots.Real Devices.Real Defects.

Mobot runs your app on real iPhones and Androids with real robots, then validates every failure before it reaches your team. Fewer scripts than Appium or Maestro. Bugs that simulators can't see. A signal-to-noise ratio your engineers will trust.

  • Real phones, operated by robots. No simulators.
  • AI-authored tests. No scripts for your team to maintain.
  • Every failure validated by a QA analyst before you see it.

The Problem

Scripted Automation Is Flaky. Simulators Are Blind.

Flaky

Scripted frameworks—wherever they run—produce flaky false failures from timing issues, brittle selectors, and environment drift. Teams burn engineering hours triaging failures that aren't bugs.

Blind

Emulators and simulators structurally cannot exercise push notifications, Bluetooth, biometrics, camera hardware, or carrier network transitions—so they pass tests that fail in the real world.

Emulators and scripted frameworks cover the first 80%. Mobot covers the 20% that actually ships broken—the last mile of mobile QA, where user trust is won or lost.

The Mobot Platform

Automate the unautomatable, end to end

Four layers that take a mobile app from generated test script to validated release — executed by robots on real iOS & Android devices, not emulators.

LAYER 04
Test Authoring
Script generation & optimization

AI explores your app builds and auto-generates test scripts across critical test cases, then validates and optimizes each script for coverage and stability before it reaches the fleet.

Auto-generated scriptsScript validationCoverage optimization
LAYER 03
Test Management
Orchestration, defects & analytics

Manages test suites and the execution queue — assigning scripts to robots and devices, tracking every run and robot action, and reporting defects and analytics same-day.

Suite managementQueue & schedulingDefect reportingRun analytics
LAYER 02
AI Driver
Computer-vision test execution

Executes test scripts on physical hardware with minimal manual intervention — computer vision recognizes on-screen UI and drives taps, swipes, and gestures.

CV-driven interactionScripted executionLimited manual touch
LAYER 01
Robot Fleet
Real devices, real gestures

Mechanical robots physically drive real iOS and Android devices the way humans actually use them — up to 3 devices at once for parallel, cross-OS coverage.

High-Signal QA: Every Defect Is Real

1

Physical Testing on Real Devices

Robots execute tests on actual phones and tablets—real taps, real swipes, real sensors—not simulated input events. Hardware-dependent defects are invisible to emulators, and they’re the ones that hit production.

2

Expert-Verified Results

Every defect is triaged and verified by a Mobot QA analyst before it reaches your team. You only ever see verified, reproducible defects with forensic evidence attached—the noise never makes it to your backlog.

3

A Platform Built for Scale

Mobot’s software authors test cases, executes massively in parallel across the robot fleet, and delivers deep defect forensics. This isn’t a body shop with robots—it’s a repeatable, consistent platform.

4

Always-On Operations

Onshore and offshore operations deliver 5x24 testing coverage. Submit a build at end of day, get verified results by morning.

Inside the lab

Real robots. Real phones. Running tonight in New York.

Every Mobot cell is a mechanical stylus over a real iOS or Android device on a lit stage. The robot taps glass, the camera sees the screen, and an analyst reviews what happened — hundreds of times a night, in parallel, across the fleet.

Not a render. Not a device farm driving phones through software. This is the hardware your tests run on.

Switching from scripted automation?

Better than Appium. Cheaper than maintaining it. Faster than writing it.

Scripted suites drive your app through software and break every time the UI moves. Mobot puts a robot on real glass and takes the scripts off your team.

Better

Real devices and real inputs instead of simulators. Every hardware path an emulator stubs is a path Mobot actually tests.

Cheaper

No scripts to build, no selectors to repair after every release, no flaky failures to triage. One program, one predictable cost.

Faster

AI generates coverage from your build; computer vision executes it on the robot. New tests in hours, and they survive the refactor.

Unified automation for every team

One platform, every mobile team

Mobot connects engineering, QA, product, marketing, and support around a single source of truth: verified defects on real devices. Choose your role to see what changes.

Mobot for Engineering

Automate tasks and accelerate development with AI-driven robotics

Engineering teams bogged down by manual processes and script maintenance can’t focus on innovation, leading to slow releases and technical debt.

  • Focus on innovation, not hotfixes
    Catch issues before they reach users so engineers can prioritize building new features.
  • Zero script maintenance
    No selectors to repair after every UI change — robots see the screen the way people do.
  • Accelerate release cycles
    Submit a build at end of day; verified results are waiting by morning.

Robot-powered testing drives results

What happens when you offload testing to robots

5 days → 1 day
I've never seen an emulator get something 100% correct. When it comes to mobile it is not the same. Nothing can beat a physical device. Feels like magic to our team. Mobot eliminates the smoke test — we can test in a day whereas a QA team would normally take multiple days.

Full matrix, every release
We stopped rationing test coverage. Now every release gets the full matrix — and our QA bill didn’t move.

34% → 12% change failure rate
Mobot helped MySwimPro reduce our Change Failure Rate by 65% — going from 34% to 12%. With less time spent on triaging and reacting to production defects, we spend more time proactively delivering new features for our members.
