When I use my Treo's built-in launcher, I sometimes think:

What if I can start an application directly by the numeric 1-9 keys?
What if I can search / filter applications by the qwerty keyboard?
What if ... (the rest you tell me ;-)

Now, here is Treo Launcher.

Summary: Very Simple, Fast & Looks Great!

I was very pleasantly surprised by Treo Launcher. I have different versions of ZLauncher, MegaLauncher and Silver Screen; while they all are excellent in different ways, for me Treo Launcher works best. The other programs just had too many options, tools and configuration choices. Treo Launcher is very simple with only one Preferences screen, it loads very fast, includes a nice split screen calendar, and works with any background image you choose... And, it only cost $12.95, trust me, that is a real bargain.

This morning when I opened my gmail, I got this photo from Leobardo Martinez - Treo Launcher running on a Abacus Fossil PDA! It's amazing!

If you have any interesting photos and wants to share with others, please drop a mail to me, horaceh @

Thanks, Leo!



The first thing I liked in Palm devices was the simple Palm OS UI. Palm has abandoned it for years. It hasn't been updated much when software titles galore on your device. So with a couple of bells and whistles to simple Palm OS launcher itself, Treo Launcher by Horace is what I have been missing on my Treo. With a type of a letter on the wonderful Treo keyboard, you can drill down your apps list to the ones you need. Still better now you can have background image like on those other Palms.

Your Launcher application is one of the best apps i have on my 700p. To me its the best Launcher todate. Its clean, sharp and effective. Its the icing on the cake for my 700p.
I love it.

Applications on CARD /Palm/Launcher folder are now supported. Each card application name comes with a '*' suffix. An application on card is copied to main memory and then launched. After the application quits, it is removed from the main memory automatically. For applications which stay in both card and main memory (as backup, for example), the main memory copy remains as is.
