GreatCircle (Palm OS) is an application for Palm OS based handhelds to compute the greatcircle distance and bearing angle between two locations on the Earth.
GreatCircle is used in conjunction with the GeoDB database application.
GreatCircle is the computation engine and GeoDB holds the location database.
TheGreatCircle archive (gc12.zip) includes GeoDB in case you do not have GeoDBinstalled in your handheld.

GPSacreage GPSacreage - Want an easy way to export the GPS data to your PC? The PDB files where GPSacreage saves the tract data is backed up on your PC each time you make a Hotsync. Now you can use another PC based application by the same developer to convert those backup PDB files to ascii text format. It makes it possible to use GPSacreage now also as GPS datalogger
RiseSet RiseSet - The RiseSet Program computes the rise, transit and set times for the Sun and the Moon.

Odometron Odometron - A basic freeware gas usage log and calculator for Palm OS handhelds. Supports up to 16 concurrent vehicles. Distance, volume, and currency are purposely referred to without specifying units so the application can be more universal. If you live in the US you can apply miles, gallons, and USD - if you live in Europe use kilometers, liters, and Euros
highSpeed highSpeed - Beeps when speed goes from watched limit, when limit is 50-53 and your speed changes from 51 to 54 kmph, sound will inform you.
Changing speed from 49 to 54 - no sound - acceleration is too fast. This can be cheated by setting lower limit to 20, for example ;-). Constant speed / slow down is not signaled.
Speeder Speeder- Program used to determine how fast a car is moving by timing how long it takes to go from piont A to point B.
I created this to assist police officers catch speeders when radar is impractical or otherwise not an option.
It could also be used by a neighborhood watch group to log speeders. Simply pre-measure two pionts and get a stopwatch out

What's New in This Release:
· Extended input accuracy to .01"
· Display of calculated distances to .0001 accuracy
