About this app
Horiz Curve is a mobile app for civil engineers and surveyors to calculate, visualize, and document horizontal curve geometry. Enter curve parameters such as bearings, radius, and location, and the app computes all key properties (tangent length, curve length, deflection angle, etc.), displays a scaled graphic, and supports coordinate geometry commands for alignment-based calculations. Features customizable units, precision, and angle formats for field and office use.
