Bubble Level + Compass Pro vs Arc Calculator

Bubble Level + Compass Pro combines a precise spirit level, compass, and Apple Watch companion app, so when your phone is placed somewhere hard to see its screen, you can still get live readings from your wrist. No more out-of-reach setups, and no more crouching. Features: • Bullseye level plus horizontal and vertical levels with 0.1 degree precision • Bubble level units: Angle (degrees) or Incline/Slope (%) • True and magnetic heading with direction text • Magnetic declination • Apple Watch companion app • Gyro or accelerometer sensor mode • Gyro calibration offset to compensate for camera bulge or uneven phone cases • Pitch/Roll/Yaw rotation rate readouts • Compass calibration status • Red-light night mode The tool is normally included in my astronomical app (Polar Scope Align Pro), but I decided to release it as a separate app because I could not find anything with the features I wanted on the app store.

Calculations at a circular corner. Here, a circular corner is a right triangle, whose acute vertices are laid on a circle, so that the right angle is outside of that circle. The resulting circular segment is subtracted from the triangle. Enter two of the three lengths of the right triangle a, b and s, as well as the circle radius r. The radius must be larger than the chord length s. Choose the number of decimal places, then click Calculate. The angle is calculated and displayed in degrees. Calculations at a round corner, or rather in a quarter circle, the most simple form of a round corner. This is the intersecting set of a square with edge length a and a circle with radius a, where one corner of the square is at the center of the circle. The missing piece, the part of the square outside the quarter circle, is also called spandrel. Enter one value and choose the number of decimal places.
