What Types of Apps Do We Test?

Various types of apps can be tested, including:

Native App Testing

Native Apps

These need to be downloaded and installed from the Google Play Store or Apple’s App Store. They often work without an internet connection and need access to different pieces of the device’s hardware, such as the camera. As such, the app and device need to work together flawlessly.

Web App Testing

Web Apps

These applications are accessed through a browser and work on all devices. One example is the mobile Facebook site, which can be used without installation. However, unlike native apps, they may not be able to access all of the device’s features.

Hybrid App Testing

Hybrid Apps

These combine the benefits of native and web apps, working across platforms and devices, and unlike web apps, can also access hardware such as the GPS sensor.

Mobile App Testing – FAQ

Here you will find answers to the most frequently asked questions about mobile app testing and clickworker’s testing solutions. For further questions, our Service Team is happy to assist you.

What Is Mobile App Testing?

Mobile app testing is the process of testing an app on various mobile devices and operating systems to ensure it runs smoothly, is user-friendly, and is free of errors. App testing should be performed on beta versions as well as after the full launch and after updates, to ensure there are no unforeseen surprises.

Why Is Mobile App Testing Important?

Mobile app testing is crucial to ensuring that your app works flawlessly on a variety of devices and operating systems. It helps identify errors, optimize usability, and increase your app's competitiveness. This is especially important, as the regular user will see an app crash and may permanently delete it in favor of a competitor’s offering without telling anyone. Clickworkers, who perform real-world testing under a variety of circumstances, can note down any crashes or bugs and report them to you, allowing your dev team to make crucial improvements.

How Can Crowdsourcing Be Used for Mobile App Testing?

Crowdsourcing allows you to deploy a large number of testers worldwide to test your app under different conditions. A particular advantage of the clickworker crowd is its global reach and the ability to segment testers according to your target audience. This provides you with comprehensive, real-world results that help you improve your app and prepare it optimally for the market. Meanwhile, you get quick results and save on maintaining a regular QA department.

What Are the Advantages of clickworker's Global Crowd?

clickworker's globally based crowd allows you to have your app tested by real users from different regions of the world. This ensures that your app works internationally and meets the diverse needs and expectations of your target audience. Additionally, you can select testers based on specific demographic criteria as well as device diversity to ensure that your app reaches exactly the people it is intended for.

How Does the Mobile App Testing Process Work with clickworker?

We will discuss your app build with you and define your test objectives together (such as functionality, usability and localization). Clickworker will then select qualified testers who match your target group. After testing, you will receive structured feedback, detailed bug reports and performance insights, all of which are consolidated in a results dashboard or via API.

Can I Test Specific Operating Systems, Devices, or App Versions?

Yes. You can specify exactly which devices, OS versions, or app builds should be tested. Our crowd includes users with a wide range of smartphones and tablets, ensuring comprehensive coverage from Android and iOS to niche or older device models.

How Quickly Can I Receive Results?

Depending on the scope and number of testers, initial results can often be delivered within 24 to 48 hours. Thanks to our scalable crowd, even large-scale tests can be completed in a short timeframe without compromising data quality.
