Screen Density is an Android app developed by Johan Westling that helps developers easily find and remember the screen density of their device. The app can be accessed for free and is categorized as a utility tool.

Upon opening the app, users will immediately see information about their device's display and display metrics, such as the width, height, orientation, and metrics. In addition, the app also displays information about the device's manufacturer, brand, device, model, SDK, and version release. The launcher icon shows the screen density of the device, which can be either ld, md, hd, xhd, xxhd, or xxxhd.

One of the most useful features of Screen Density is that users can easily share the information displayed by selecting the Share option from the action bar or options menu. It is important to note that this app is primarily useful for Android developers who need to quickly reference their device's screen density.
