What makes an mobile app or game successful?


The Challenge: Strong competition in the mobile market

Mobile apps and games have to make a good impression when it comes to their functionality and usability. Unfortunately, extensive usability testing is often overlooked. This can lead to apps that don’t satisfy the necessities of their target group or that aren’t able to fulfil their purpose. The majority apps are therefore never used more than once. If you want to make sure that your mobile apps and games are a perfect fit for your audience – test them before the go to market with the help of our crowd.

The Solution: Providing a high product quality with functional testing

In addition, it’s important to assure that apps work on all relevant devices and operating systems and that they perform as they should. If you just take Android OS in consideration – developers had to deal in 2018 with more than 11 different versions in the market. For example, it’s possible that some errors like crashes only occur on certain device combinations such as a Samsung Galaxy S20 running Android version 10. However, few companies are able to access hundreds of different combinations of operating systems, browsers, software and devices that would allow them to test for such defects. So the solution is eas – simply tackle device diversity using millions of possible combinations available in our crowd as real devices.

The types of apps we test


Native apps

A native app has to first be downloaded from Google Play or the iTunes app store and then installed onto a device. The program, for example a calendar, often works with or without internet connectivity and is able to access a device’s hardware features (camera, microphone, etc.).


Web apps

This application looks like an app but is runs in browsers. It works on all kinds of devices but cannot access all hardware parts like native apps can. The mobile Facebook website is a well-known example of a web app that can be used without installation.


Hybrid apps

A hybrid app combines the advantages of native and web app. It works platform- and device-independent. Therefore there is only one version, that can be used browser based on smartphone and tablets with iOS, Android and Windows. In contrast to the web app, the hybrid app can also access hardware such as the GPS sensor.
