Decimal Compass

Project Overview

Decimal Compass is a simple yet powerful compass and location app designed for real-world use. While your phone's built-in compass shows where you're facing, Decimal Compass shows where you ARE - and remembers it. The app displays your current location in easy-to-read decimal degrees format and allows you to save unlimited locations with optional notes for future reference.

Perfect For

Decimal Compass is designed for anyone who needs to save and share exact locations:

• Hikers marking trail points, campsites, and points of interest
• Drivers remembering parking spots in large lots or unfamiliar areas
• Outdoor enthusiasts sharing fishing holes, hunting spots, and scenic viewpoints
• Emergency responders needing precise coordinates for incident reporting
• Contractors and surveyors marking job site locations
• Travelers documenting interesting locations for future visits

Why Decimal Coordinates?

Traditional GPS coordinates use degrees, minutes, and seconds (e.g., 43°39'25.7"N), which are difficult to read, type, and share. Decimal degrees (e.g., 43.657139) are:

• Easier to read and understand at a glance
• Simpler to type and share via text or email
• Compatible with all major mapping services
• Standard format used by most modern GPS devices
• More precise for exact location marking

Privacy & Security

Your location data stays on your device:

• All saved locations stored locally on your iPhone
• No cloud storage or data transmission
• No account creation or personal information required
• Location sharing only happens when you explicitly choose to share
