What I love about the Palm OS is the sheer range of applications available for the platform that cater for a wealth of different minority interests or uses.
For instance, AmbTime is a program that allows you to track ambulance responses to incidents. It provides a quick way of recording the time at each stage of the callout and response process, which can be used to monitor worker's performance and analyze areas for improvement.
The program's main interface is designed for touchscreen use and consists of seven different buttons representing each stage of the process, namely: Call Received, EnRoute, Arrive at Scene, From Scene, At Destination, In Service, In Quarters. What I like about this menu is the fact that all you need to do is touch a button and it automatically records the time and inserts it next to each stage. What I didn't like was that there was no protection against hitting the wrong button out of sequence.
AmbTime is highly customizable and you can set your own button names and insert unlimited timer groups.
This means that it's not just ambulance crews who can use it, but rather anyone who needs to quickly monitor times at each stage of a sequence of events.
