Coordinate Calc (Traverse)

This coordinate calculation app features traverse and reverse traverse calculation functions and can import CSV text data.
We hope you will find it useful as a simple and easy-to-use coordinate calculation app for civil engineering, surveying, and other construction surveying.

The November 2024 update significantly updated the app, adding the ability to input and output reverse traverse calculation (surveying and design calculation) results.
In addition to the existing features, we added a function that makes it easy to save and share coordinate data and surveying and design calculation results externally.

The November 2025 update now supports English and Japanese.

We offer simple, easy-to-use functionality for those who don't need complex functions.
You can use it with peace of mind, with no ads, no additional charges, and no data collection.
