Smart Protractor downloads
Worldwide, per day, and installs to date. The band is open; the exact number is free with an account.
How this is calculated
Apple publishes no download counts. App Store downloads come from chart positions and daily rating growth per country, calibrated on Google Play install counts; lifetime installs from ratings worldwide × installs per rating. Confidence is the chance the real number is within half to double ours.

Review momentum
54/100
faster than 56% of Utilities apps
Review momentum (0-100) blends how fast the app collects ratings compared with other apps in its category (60%), whether that pace is speeding up (25%) and what recent raters give it (15%; recent stars well below lifetime pull it down). Ratings counts are read daily. A jump usually means a launch, a feature, ads or a new review prompt.
About Smart Protractor
Protractor - smart instrument to measure angles. Turn on the camera mode and measure the angle of buildings, mountains, or any other object around you.
This app includes two free measuring modes:
- Touch measure - touch the screen to set the angle (use camera view!).
- Plumb bob measure - pendulum - use to determine the slope (remember to calibrate the plumb).
In each mode, you can switch to camera view and take measurements of all objects around you.
Additional Premium mode: Polygon measurement lets you draw any shape on your screen to check all its angles. Turn on the camera to see the real object through your phone and copy its shape. You can also pick a photo from your gallery or take a new picture to draw a shape on the image. In Premium mode, you can change colors, add helper lines, and switch between different angle units.
All modes allows you to make a screenshot of anything on the screen.
Enjoy !!!
