About this app

Vector Pad — Precision Math Lab turns your phone into a standalone engineering tool with the feel of a professional lab.

PRIVACY BY ARCHITECTURE
There is no uses-permission in the final AndroidManifest.xml. The app does not request access to the Internet, camera, contacts, geolocation, or external storage. All calculations and drawings are processed locally. No registration, advertising, analytics, or trackers.

WORKS IN ANY CONDITIONS
On a remote site, in the lab, or in production, Vector Pad works offline. Install the app and start calculating.

LIVE GEOMETRY
A custom canvas with a coordinate grid smoothly rebuilds the drawing after each parameter change. Move the sliders for quick adjustments or enter precise values ​​manually. The proportions of the figure are preserved during automatic scaling.

FOUR ENGINEERING MODES
• Right triangle: area, perimeter, hypotenuse, angles, sine, cosine, and tangent.
• Sector of a circle: area, arc, chord, and perimeter.
• Cylinder: volume, total and lateral surface area, base area.
• 2D vector: magnitude, direction, and unit components.

PREMIUM INDUSTRIAL DESIGN
Matte graphite, platinum edges, cobalt axes, and contrasting gold accent. Monospace numbers and a large scoreboard make technical data easy to read. Reset Matrix returns to the original settings with smooth animation.

Android 9.0 and higher. Double precision, clearly stated units of measurement, and formulas next to the results. Your pocket math stand is completely autonomous.
