FullMoon app for iPhone and iPad

FullMoon is a full Hijri Calendar for any Hijri year between -9999 to +9999 and is a further development of TheMoon (daily Hijri Lunar calendar).
It provides the moon phase and the date for the current day, as well as a month view for any month of any year.
The days containing Special Dates in each month are marked with the appropriately colored frame: green (happy), black (sad), and (brown) neutral.
Tapping on any day of the monthly calendar displays the details of the Special Events for that day.
There are two settings for the choice of the Special Days shown:
(1) "Basic", which shows 13 Special Dates recognized by all Muslims around the world, and (2) "All", which shows over 100 Special Dates recognized in some part of the Muslim World.
The start of the current month can be adjusted for moon sightings with automatic addition of day 30 ant the end of a month, if necessary.
It is also possible to set the time of the change of the moon phase between after 12.00 (13:00) and after 23:00 (24:00).
Events of interest can be selected to be shown on the Lock Screen as the next event.
