Hi, I’m a fan of your fabulous iOS app “Sky Live” to check the condition for shooting starry sky photos in Japan.
One thing that I’d suppose is confusing is the translation of “User Manual” in “Menu” into Japanese. Currently shown is “手動,” which means “operation by hands.”
We use different words between “operation by hands” and “handbook” for “Manual”; the former in the menu may not make sense to the app users.
My recommendations are:
or simply shortened
Please consider the correction on your further update.
