MyMap is to find the correct device heading to the target. While the app continuously displays current location with heading,
the target can be set by 1. Latitude/Longitude or 2. Address, or 3. Records or 4. Click-on-Map.
This is specially useful where the address is not available such as mountains or sea area.
[Usage]
1. Place device in PORTRAIT mode with FLAT position
(Note: Stay away from strong magnet. Check phone case!)
2. Set target
3. Align Device Heading (Green) toward Target Direction (Red)
