## What is FULL COMPASS?

This compass allows you to instantly switch between Japanese directions ("東西南北") and English abbreviations ("NESW") with a single tap.
It not only shows directions but also functions as a level gauge, altimeter, latitude/longitude display, and smartphone tilt indicator.

The compass supports 16 directional points and displays both cardinal names and precise angles in degrees (0–360°).
You can switch the language between Japanese and English via the menu.

In addition to vertical and horizontal leveling, the app graphically displays the phone's tilt using four gyro indicators.
You can choose between two design styles: a mechanical "Gray Metallic" or a classic "Black".
These can be changed from the settings menu.

It also serves as an "Eho‑maki Compass" for Setsubun, helping you find the lucky direction to eat your Eho-maki.
The directions "North-northwest", "Northeast by east", "South-southeast", and "Southwest by west" are available in Japanese.

In 2026, Setsubun falls on February 3rd. The lucky direction for Eho-maki is South-southeast.
Use this app to easily find that direction and enjoy your Setsubun traditions!

We've resolved an issue where the app could be installed on devices lacking a magnetic sensor.
※Please note: the compass function requires a magnetic sensor and may not work properly on unsupported devices.

We also added a new feature that detects environments where compass readings are unstable and provides troubleshooting guidance.

Additional features include the ability to hide banner ads and use the app offline, perfect for use in the mountains or by the sea.
