The 'One and Done' Utility
There are apps you keep on your home screen for years, and then there are apps like Screenwise. You download this because you are standing in an aisle at Costco or staring at a blank wall in your basement trying to justify a massive purchase. It exists to settle arguments about whether a screen is 'too big' or if the resolution actually matters at a ten-foot distance.
For most families, this is a tool for the parents. However, there is a specific type of kid—the one who spends their weekends on PCPartPicker or watching tech YouTubers—who might actually find the 'Advanced Screen Calculator' interesting. It breaks down the relationship between physical size, resolution, and pixel density. In a world where every device is a 'Retina' display, understanding the actual math of PPI (pixels per inch) is a decent, stealthy way to introduce some practical geometry and physics.
Is it fun? No. Is it useful? Yes, for exactly fifteen minutes every five years when you buy a new monitor. If you're looking for something to keep a kid occupied, this isn't it. If you're looking to verify that your kid's gaming setup isn't going to cause unnecessary eye strain, it is a solid, safe, and free way to check.
