This program is for Pocket PC (PPC) enabled PDAs it simply registers screen taps and records the time of the tap.
Designed for recording the timings of lunar grazings, lunar ocultations, asteroid occultations transits, meteor showers and any other astronomical observation that needs a record of the date and time to the nearest 10th of a second.
The time of each event is recorded on the screen and passed to the clipboard on exit, so can be pasted into any application.

The Earth&Sun an application for Ewe enabled computers. It shows the Sun Illuminated area of the Earth.
It also displays:
- The latitude and longitude of an Earth location.
- The time zone at that location, based on only longitude not civil boundaries.
- The current time at that location based on the above time zone.
- The sunrise and sunset times, and day length at that location.
- Distance between two locations on the earth surface.

Ephemeris is a program that lets you enter a date and a location and then computes the time and azimuth (compass bearing) or sunrise, sunset, moonrise and moonset. In addition, it displays a schematic representation of the phase of the moon and its % illumination.
It can also generate a table listing the positions of the sun and moon in the sky and the length of shadows cast by the sun at 15 minute intervals for a given day.
In Calendar mode, it can display the phases of the moon for any given month.

GeomagInfo computes the magnetic declination for magnetic compass correction and more.
The GeomagInfo is an application for Ewe enabled computers to compute the magnetic declination, inclination, and magnitude for any location on Earth.
Its main use is to give the current magnetic declination to correct a magnetic compass. This application is most useful for those hiking and traveling without topographic maps in unfamiliar territory. A magnetic compass can be off by many 10s of degrees in parts of the world.

GreatCircle is an application for Ewe enabled computers to compute the great circle distance and bearing angle between two locations on Earth.
GreatCircle displays the following data:
- Latitude and longitude of two Earth locations -- selected from included Location Data CSV files and/or entered manually.
- The great circle distance between the locations in either: kilometers, nautical miles, statute miles, meters or feet.
- The great circle bearing angle in either: degrees or grads, from the From locations to the To location.

Astronomy software for the Pocket PC (PPC) PDA palm sized computer.
Gives the enthusiastic astronomer the positions of Jupiters satellites, Great Red Spot (GRS) and a map of Jupiters features all in one single convenient package, and its FREE!
Features:
- Show positions of Jupiters satellites.
- Flip view E/W and/or N/S to show the same orientation as your set up.
- View edge on, Plan or a wavey diagram.
.. Change the size of Plan and Edge on views.

Pocket PC application simulating the night sky.Update
v1.2:
- Added labels of grid coordinates.
- Fixed a stupid bug in the Julian date calculation - cause of wrong stars possitions.

Riseset is an application for Ewe enabled computers to compute sighting information for the Sun, Moon, Mercury, Venus, Mars, Jupiter and Saturn. Any user location and date may be specified.
Features:
- Rise, transit, set times.
- The altitude and azimuth angles at the current time, or at a user specified time.
- A compass drawing showing the azimuth and altitude angles.
- Optional magnetic compass correction for azimuth angles.

SunnMoon is a today plugin which shows the set and the rise of the Sun and of the Moon. It also shows the moon phase.
Features:
- Small: takes about 90KB of your PDA memory.
- No Internet needed: calculates the set and rise of the Sun and the Moon from you geographical position.
- Hi-DPI aware: designed in modern manners, it is ready for VGA displayes.
- Time format: choose between 12 hour or 24 hour time format to have the information about sets and rises displayed in the way common for you.
