![]() ![]() This estimate came from randomly showing or removing the purpose string included with each request, as designed by its vendor, even when the explanation was fairly poor. In one study of 15 mobile apps, Tan and his colleagues found that users were 12% more likely to grant a permission request when they were given a reason for the request. The best permission requests communicate the rationale behind the request. 3 Design Considerationsģ design considerations greatly affect the quality of a permission request. They may even consider uninstalling the app and looking to competitors, especially if the app’s brand isn’t strong and the functionality doesn’t provide great utility. On the other hand, when permission requests are designed poorly, users often feel uncomfortable, confused, and irritated. When permission requests are designed well, they seem reasonable and nonintrusive users barely think twice when dealing with them. However, app permission requests contribute to the overall user experience and should follow the same usability principles as other features. After all, who wouldn’t want to give access to every resource so they may use all the excellent functionality? It may also be hard for UX designers and app developers to understand why permission requests are so important. ![]() One reason could be that permission requests are often not considered to be part of UX design, because the UI component for the permission itself is dictated by the operating system. As a result, users need to trust that the app won’t ever maliciously access resources.Īpp permission requests are still often poorly designed, despite fairly extensive guidance from the iOS and Android development community. The decision to allow access can be a significant one, as the app often retains access to the resource until users uninstall the app or deliberately revoke the permission in their device’s permission settings. Permission requests give users perceived and actual control over their personal (and potentially sensitive) data. It’s up to Android designers to ensure that the rationale behind the request is introduced before the modal dialog appears. This type of information is not present in Android. Moreover, in iOS, the modal dialog contains what’s called a purpose string, which describes why the app is requesting access. ![]() As you can see from the example above, in iOS the user is asked for access to the microphone, whereas in Android the user is asked for permission to record audio. There are slight differences in how these requests are presented across mobile operating systems. Google Translate requires access to the microphone to use the dictation feature iOS (left) and Android (right) permission requests differ slightly. The app sends (via the operating system) a request in the form of a modal dialog, asking the user to grant or decline access. What Are Permission Requests and Why Have Them?Īn app must request permission before accessing resources such as the camera, current location, or microphone, on the user’s mobile device. ![]()
