DiaLog (Diabetic Logbook) is a memo application for all diabetics with a Palm Pilot. It enables you to enter your diabetes-related data quickly and easily and to view them later sorted by date. Additionaly, you can calculate the neccesary amount of insulin you will need, based on the sugar and food you're going to eat.
Ostiary allows a client to run scripts on a server in a secure, authenticated manner, using an extremely simple protocol that is immune to buffer-overflow attacks. It is useful as a limited ssh/lsh replacement, or to selectively enable full remote shell access on a temporary basis. Clients for Windows, Unix, iOS, Android, and Palm are available.
QuickType is a Palm extension to help improve text input on Palm OS devices. It is not a built-in keyboard or Graffiti replacement, but rather a supplement. It makes it easier to input the more common information quickly. For punctuation, numbers, and special characters, you will still need to use either Graffiti or the built-in keyboard.
IconsPlus is a system preference panel which can set your favorite icons for any applications on your device. The icon will be changed globally for any third-party application or launcher. IconsPlus stores icons in its own iconpack format and supports icon storage formats of two popular launchers (ZLauncher and SilverScreen), which gives you a wide range of choices. It requires Palm OS 5.0 or later.
