Let BlueStacks turn your PC, Mac, or laptop into the perfect home for Smart Protractor, a fun Tools app from Smart Tools co..
Smart Protractor is a simple angle and slope tool that actually feels handy once it is running on a bigger screen with BlueStacks. The app gives three ways to measure. Touch mode is the easy one, where someone places an edge or a photo against the screen and drags the virtual arms until they match the angle. Plumb mode treats the device like a hanging weight to show slope, useful if the hardware can tilt, though on a desk setup that part feels less natural. Camera mode is the neat trick, overlaying a goniometer on the live view so a person can line up edges in real space and read the degrees without guessing. On a laptop webcam it is not perfect, but it works well enough for quick checks.
The layout is clean, nothing fussy, and switching units is fast. Degrees, percent grade, or radians are there, so no mental math. Zero calibration helps when the surface is not perfectly flat, and the orientation sensor toggle keeps the reading from jumping if the device shifts. The paid upgrade removes ads and throws in extras like screen capture, a ruler, a basic level, and even thread pitch for screws, which is oddly useful if someone tinkers. It feels more like a toolbox than a flashy app, and that is the point. For hanging frames, checking a cut, or laying out a small DIY project, it gets the job done without drama.
Big screen. Bigger performance. Use BlueStacks on your PC or Mac to run your favorite apps.
