What makes an app successful?

The competition is strong: usability as a success factor
Applications have to make a good impression when it comes to their functionality and usability. Unfortunately, extensive 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.

Quality assurance: Device diversity as a challenge
In addition, it’s important to assure that apps work on all relevant devices and operating systems and that they perform as they should. For example, it’s possible that some errors like crashes only occur on certain device combinations such as a Samsung Galaxy S4 running Android version 4.4. 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.

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.


USABILITY & UX: Comparison Study “Curating and creating content is just part of the challenge we face. With so much competition and ‘digital noise’ the discovery of content is often an even bigger obstacle for content creators; the research carried out by Testbirds proved our instincts were right with a combination of invaluable anecdotal and quantitative data. The process was clear and the team at Testbirds provided useful feedback and advice throughout.” David Kane, Director of Editorial Content, VEON


USABILITY & UX: Remote Interviews
“We looked at other vendors, but quickly decided to work with Testbirds. (..) Most importantly, Testbirds was able to provide the right testers and the company is a very flexible service provider that has implemented the projects quickly and smoothly.”
Dr. Jochen Münchenberg, Founding member of the Interhyp Zukunftswerkstatt.
