About the app and purpose
PPI Calc — DPI Calculator is a complimentary mobile utility created by AppNextDoor Labs that helps you measure how tightly packed pixels are on a screen. It’s built to give a quick answer about display sharpness using a few basic inputs and a minimal learning curve.
How to calculate pixel density
To find a display’s pixels-per-inch (PPI), enter the diagonal size in inches and the screen resolution as horizontal and vertical pixel counts. Press the calculate button, and the tool returns the exact PPI based on those numbers.
Primary capabilities
- Shows calculated PPI for any display when you provide diagonal size and resolution
- Computes related values such as dot pitch, megapixel total, and derived display dimensions
- Offers a tidy, easy-to-navigate interface so you can start using it immediately
- Distributed at no cost for mobile devices from AppNextDoor Labs
- Focuses on delivering the essentials without excessive complexity
Limitations to be aware of
The app prioritizes simplicity, which means it doesn’t include the deeper technical breakdowns or advanced comparison features found in some more comprehensive utilities. If you need highly detailed analysis or extra configuration options, you might find this tool a bit light.
Who will get the most from it
If you want a straightforward way to check how dense a screen is or to approximate display characteristics without fuss, this app is a convenient choice. It’s especially handy for quick checks on phones, tablets, and monitors when you only need basic, reliable metrics.
