## What is Diamond X Lite?

Since GPS and Web maps can be used, diamonds from any location are OK.
Diamonds other than Mt. Fuji are also OK.
Data on more than 1200 mountains all over Japan, Tokyo Metropolitan Government Building, Tokyo Tower, Tokyo Sky Tree, etc. are built-in.
As with "Yamaotaku for Mac (Yamac)", the curvature of the earth and atmospheric refraction are taken into consideration, and highly accurate results can be obtained.
It supports Japanese and English display and automatically switches according to the setting of the language used on the iPhone.
You can share location data files with your Mac or Windows.

Diamond X Lite is a trial version and has the following restrictions.
The diamond display period is within 6 months, the diamond type is fixed, the setting information is not saved, the use of shared files is restricted, etc., but the paid version of Diamond X has no functional restrictions.
