BrowserStack has launched App Percy, an exciting new tool designed to make visual testing for mobile apps easier and more efficient. Instead of developers manually hunting down visual bugs, App Percy uses automation and AI to spot any issues with your app's design across different devices and screen sizes. This ensures that no matter what device your app is on, it looks just as it should.

Why Developers Will Love App Percy
App Percy runs on BrowserStack’s real device cloud, which gives you access to over 20,000 real devices. The best part? You’re testing on actual devices, not emulators or simulators, so you get accurate results every time.
Nakul Aggarwal, the Co-founder and CTO of BrowserStack, explained it perfectly: “App Percy makes life easier for native app developers. Instead of spending hours manually checking for false positives, developers can focus on fixing the bugs that truly matter.” And setting it up is a breeze—it only requires a single line of code to get started, making it perfect for integrating into existing workflows.
How Easy is App Percy to Set Up?
App Percy is designed to get you going in just three simple steps:
- Install the SDK
- Add a single line of code
- Run your builds and start reviewing
From here, App Percy will start capturing screenshots and comparing them automatically. This makes visual testing much faster and smoother because you won’t need to write complicated test scripts.
Key Features of App Percy
App Percy is packed with tools to help you quickly spot any design issues with your app. Each time you push new changes, App Percy grabs screenshots and compares them with previous versions, so you know instantly if something looks off.
Here are some standout features:
- Automatic Diff Matching: App Percy groups together screenshots that show similar changes, so you can review all of them in one go. You can also dive deeper and look at individual screenshots if needed.
- Diff Highlighter: Highlights the specific parts of the image that have changed, helping you catch issues at a glance.
- Configurable Diff Sensitivity: Adjust how strict or relaxed the comparison is, depending on the requirements of your project.
- AI-Powered Percy Visual Engine: This engine smartly handles things like page shifts and small visual differences, focusing only on what really matters.
- Page Shift Detection: Instead of flagging an entire page, it zeroes in on the exact pixels causing the page to shift.
- Ignore Regions: If certain parts of your app (like dynamic dates) don’t matter for visual testing, you can simply ignore them, making tests more reliable.
- Integrated Workflows: App Percy fits seamlessly into your existing workflow, keeping track of baselines and approvals so you can keep reviews efficient and organized.
A Tool for All Developers
Whether you’re working on native apps, hybrid apps, or style guides, App Percy integrates smoothly into your workflow. It supports major testing frameworks like Appium, Java, Python, C#, Ruby, and more. And for open-source software developers, App Percy also supports public projects, allowing contributors to see the visual impact of code changes.
Conclusion: Simplifying Visual Testing for All
With App Percy, BrowserStack has created a powerful tool that makes visual testing for mobile apps simple, fast, and accurate. Developers can now ensure that their apps look flawless across all devices, without the hassle of manual testing. Whether you’re testing the visuals of a native or hybrid app, App Percy has you covered, giving you more time to focus on what really matters—building great apps.
