About Geodetic Compass

Your MUST HAVE app trekking or hiking in Taiwan!

Super fast to send or share location:

1. Open compass app

2. Check satellite signal strength at bottom left corner and then press send button.

3. Fill in custom text or SOS form.

4. Send!

After installation, two launch icons will be shown in your apps.

1. The compass acquires your location in real time. Then you can share your location by SMS or by other apps. A built-in phone book of fire departments will be shown if your current location was considered to be in Taiwan. These phone numbers were integrated with Taiwan's 911 system to receive SOS message from SMS.

2. Coordinate conversion tool supports several common coordinate formats in Taiwan. It also supports Taipower geocoding, which was marked on most utility poles in Taiwan.

NOTE!! No warranty about the accuracy of compass and positioning. Please be aware that this app is not intended for critical or high accurate measurements.

Please support Leave-No-Trace policy and help protect our mother nature together!

Offline maps: see where you are even with no signal.

OFFLINE MAPS
• Download Rudy Map Lite in Settings → Offline maps (about 204 MB, Wi-Fi recommended). It covers all of Taiwan.
• The compass map then uses it automatically.

HONEST POSITION
• After a minute without a new fix, the position is marked "last position" with its age, and sharing warns you.
• With no fix, the map shows your last position.

Rudy Map is made by Rudy Chung from OpenStreetMap data.
