About Diamond X2
This app is the successor to "Diamond X" and makes it easy to find the date and time of Diamond Fuji.
Use GPS and web maps to create diamonds from any location.
Diamonds other than Mount Fuji are also supported.
Built-in data for over 1,200 mountains across Japan, as well as the Tokyo Metropolitan Government Building Observatory, Tokyo Tower, Tokyo Skytree, and more.
Like "Yamaotaku for Mac (Yamac)," it takes into account the Earth's curvature and atmospheric refraction to provide highly accurate results.
Supports Japanese and English display, automatically switching based on your iPhone's language setting.
Location data files can be shared with Mac and Windows.
Differences from "Diamond X"
1. Diamond-eligible locations are now checked in the location selection list. This allows you to quickly find diamond-eligible locations. Calculation speed has been significantly improved, allowing for stress-free use of this feature.
2. Mount Fuji can now be displayed from any location, regardless of whether diamonds are available.
3. The sun's altitude and shape reflect atmospheric refraction. (At low altitudes, the display will be compressed vertically.)
4. Sunrise and sunset times for a specified period can be displayed as a list.
5. Improved support for calculation errors.
6. Improved calculation accuracy.
7. Multi-core support significantly improves calculation processing performance.
8. Added a function to transfer calculation results to other apps.
9. The UTC offset corresponding to the viewpoint's time zone can now be set automatically or manually, enabling support for time zones other than Japan.
10. Help is now available for some functions. (Tap the ? icon to display it.)
11. Instructions for sharing files with your PC, such as myData, are now displayed.
12. Support for more languages is now available.
13. Added an on/off switch for transparency.
14. Diamond offset display can now be selected between "meters" and "degrees."
15. Added a new switch for resetting settings.
