AngleVectorCirclion is a handy angle and triangle calculator made for quick everyday use. Normalize any angle to the 0–360 range and instantly find the shortest angle difference between two directions. Get the circular mean of multiple angles without the usual wrap-around confusion. Convert an angle to slope percent, or turn a slope percent back into an angle in one step. From an angle and a length, calculate rise and run for clean layout, ramp, and drawing work. Solve right triangles fast by finding the hypotenuse, adjacent, or opposite side when you know the needed values. Measure the vector angle between two lines to compare directions accurately. A simple settings area keeps the app easy to use, and the About, Rate, and Share options are included for quick access. Designed to be clear, fast, and practical when you need angle and vector results on the go.
