My main PDA is a Palm m500 which runs Palm OS 4. I think all of these applications will work on Palm OS 3.5 and up but I have only tested them on 4.
This is all roughly 20 year old software, some of it freeware or open source but much of it was shareware that required registering with a serial number to unlock. Some of these included an already cracked file that can be installed as normal. The rest can be registered with the codez below and the MultiUserHack(available below in the Hacks section) to change the hotysnc id.

Outliner, task manager, organizational tool that is very powerful. I use it to plan each issue of smolZINE.
Kind of my killer app for my Palm PDA. It is a text editor that has all the basics covered nicely and can edit and save directly on an external SD card. This combined with one of the Palm folding keyboards makes for a nice distraction free writing device and I write most of my gemlog posts for my capsule with it.
Handy and easy to use unit converter for tons of different things. Volume measurements, units of power, temperature and pretty much anything else you might need.
Datebook (what is usually just called a calendar these days) software that has a ton of features that I have barely scratched the surface of. Word on the street is that this is indespensible for heavy users with lots of appointments. Probably overkill for basic needs but I keep it around because of the nice extra calendar views alone. Pretty large so may not be worth it if you are low on space.
Exacly what is sounds like and no more. It has buttons to simulate rolling different types of die. Useful for various types of games. I plan to use the 4 sided dice for playing the Royal Game of Ur.
Sketch pad, notepad and reminder app. It has fairly sophisticated drawing tools considering the platform. The alarm function means you can jot down a quick note or reminder and the note will reappear at the specified time which can be pretty handy.
File manager that can show you some useful information and lets you browse and perform basic file management on the internal memory and SD card.
Really well done shopping list manager. Saves list items so all you have to do is re-add them to the "need" list for things you need often like groceries. It can even track and keep history of prices of items on your lists. You can create lists for specific stores, put lists into categories and it even has a one hand mode for checking off items with the hardware buttons to make it easy to do while grocery shopping. Excellent stuff!
Has one very simple task, invert the display. On monochrome displays with the backlight on sometimes inverting the display can make things much easier to look at.
Pretty much a carbon copy of the stock Palm OS todo app. The purpose is that since it is a separate app from the defualt todo you can put your less urgent tasks here and then when they become more urgent you can move them to the main todo list.
Shows the time and date with a matrix style cryptic text scroll animation background. Can be useful as a desk clock when your PDA is in the cradle but mostly its just cool and fun.
Souped up version of the stock memo pad app. Kind of similar to DiddleBug it lets you draw with the stylus and set alarms. You can also enter text memos with graffiti just like the basic memo pad.
Universal remote that can learn the commands from any remote you have. How cool is that?!
Ebook reader software that comes in 3 flavors, lite, regular and pro. Lite is very small and has the fewest features but can be good if you're low on free space. The standard and pro versions each add more features as well as increase the program size.
You will need this in order to install the hacks listed below. Facilitates "hacks" which are small programs that modify some lower level aspects of the OS to change the way certain things work. The gist is you install X-Master, then install a hack, after that you open X-Master where you can enable/disable the hack and configure whatever options the hack provides you with.
This hack is pretty neat. It lets you install some mini versions of apps that are called "Desk Accessories". What this does is enables some limited multi-tasking not normally possible in Palm OS. These DAs can be launched in a window over top of the currently running application. Another thing it does is add a little shortcut to your home button that can quickly launch apps from a popup list, a condensed list of your recently used apps and a gesture to immediately launch the last used app.
Modifies the graffiti entry so that you can write letters straddling the line between the letter and number area in order to write capital letters. This can speed up text entry by skipping the step of enabling shift or capslock.
A very handy hack that lets you set a different HotSync ID for individual applications. This is vital for using cracked serial numbers to register shareware applications.
Good space invaders/galaga/galaxian clone.
Simple puzzle game.
Rogue for Palm OS!
Cool puzzle game where you roll a ball around levels with the stylus to reach the goal with hazards and keys to collect along the way.
Game Boy emulator. The Game Boy roms need to be converted with an included tool and at least on my m500 most games don't run at full speed. Still, it's pretty neat! Probably best for turn based, puzzle and other non-action games unless you're playing on a more powrful PDA.
Phoinix website with more lanuages and other downloads with preconverted games
Fancy breakout style game that plays pretty nicely.
A racing card game that I was and now am again so so addicted to X-).
There are number of different sokoban games on the Palm. Here are a couple that I've tried.
Really good and open source puzzle game. If you're familiar with the Tatio game Puzznic that was released for arcades, NES, Game Boy and other systems Vexed is pretty much that except you move the blocks around with the stylus.
Remake of the classic space exploration and combat sim Elite.
It's wordle for Palm OS!
A word game that is a variation on the Boggle style of gameplay where you select adjacent letters to form as many words as you can.
