Any Palm OS hardware
Palm OS 5.2

The most powerful and versatile skydivers logging software on the market. Paralog supports just about every feature a jumper could want for keeping accurate and detailed logs of their sport or military skydiving career. Using the most popular PDA platform, jumpers can enter their jump logs right on the DZ just as they would with a paper based logbook and even capture a digital signature from a witness.

Features:
* Automatically calculate freefall time, provide a custom calculation or manually enter a freefall delay taken from a dive computer.
* Maintain personal profile such as licenses, ratings, awards and membership details.
* Track up to 4 separate rigs including serial numbers, inspection dates and AAD maintenance details.
* Use either the Imperial or Metric scaling system depending on locale.
* Signature input to allow other jumpers to witness dives right at the drop zone.
* Quickly view or edit jump logs with user selectable sorting orders or navigate directly to a given jump number.
* Alarm feature to notify when membership, rig inspection and AAD inspections are approaching.
* Graphical charts and reports for quick performance evaluation.
* Multi log witness verification to allow other jumpers to validate several jumps while only having to enter their personal info and signature once.
* Supports all devices running Palm OS 5 and above.
