Curvature: The Ultimate Earth Measurement Toolkit
Built from the ground up. Literally.

Welcome to the all-new Curvature, the most comprehensive tool for exploring, calculating, and documenting earth measurements. We have completely redesigned the app experience—new code, a sleek modern layout, and powerful features designed for researchers, students, and enthusiasts alike.

Whether you are analyzing globe geometry or exploring flat earth models, Curvature provides the advanced formulation and high-precision tools you need to visualize the world around you.

What’s New in Curvature?

### Advanced Earth Calculators

The Curvature Calculator: Our flagship tool now uses advanced formulation for more accurate results. For the first time, see your calculations come to life with a graphic representation of the results.

Quick Horizon Calculator: Instantly find the distance to the horizon based on your height of eye.

Quick Curvature Drop: A streamlined tool for rapid drop-distance results.

Formula Transparency: Access a dedicated section showing the exact formulas used for both globe and flat earth models.

### Redesigned Mapping & POIs

Precision Tools: Utilize the new measurement ruler to calculate distances directly on the map.

Points of Interest (POI): Drop pins on key locations and save them for future reference.

Data Persistence: Powered by SwiftData, your saved measurements, POIs, and calculations are stored securely in organized folders on your device.

### The Knowledge Hub

Expanded PDF Library: A high-performance PDF viewer that allows you to organize research. Pro Feature: You can now import and store your own PDF documents directly within the app.

Categorized Links: An improved card-style layout for web resources. Add your own custom links and categorize them to build your personal research database.

Comprehensive Glossary: A deep dive into the terminology of both globe and flat earth models.

Geographical References: A library of data points and geographical milestones for quick fact-checking.

### All-in-One Utility

Universal Unit Converter: Seamlessly convert between Distance, Speed, Weight, Temperature, Area, Volume, and Time.

Save & Export: Keep a permanent record of your findings with the ability to save every calculation you perform.

Modern. Clean. Accurate. Curvature is more than just a calculator; it’s a portable research laboratory. By providing the tools to calculate "the drop" and visualize the results, we put the power of observation and mathematics in your pocket.
