CoGo Calculator is a comprehensive Android application built for surveying and coordinate geometry tasks. The app allows users to initialize points with x/y coordinates, then generate new points using bearings, distances, offsets, traverses, radiations, or secants. Beyond point entry, it includes modules for joins, rotations, shifts, scale factors, and DMS conversions, making it a versatile tool for field engineers, surveyors, and students.
The app organizes work into jobs, with a built‑in file manager to save, load, and manage calculations directly on the device. Each calculation module is accessible as a dedicated activity, ensuring clarity and modularity. Features like Feet‑to‑Meters conversion, point data analysis, and line/offset calculations extend its utility beyond basic geometry.
Designed as a standalone Android solution, CoGo Calaculator demonstrates practical handling of coordinate geometry, persistent data storage, and multi‑activity architecture without reliance on external libraries.
Tech stack: Java (Android app logic and UI), Android SDK, Custom geometry algorithms (bearing, offset, traverse, rotation, scaling), File Manager integration for saving and loading calculations
