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)
