This is what I've been looking for in astronomical freeware. I'm not an astronomy enthusist, but primarily want to know sunrise/set, moonrise/set as I spend a good deal of time outdoors. Also want to know the moon phases. This app does the job. It will get the 5th star when it becomes hi-res+!

I have been using AI (AstroInfo) since version 1.02a on a Palm Vx. I am very please with it. I recently acquired a Tungsten T3. The current version did not work. After contacting their mail service, I receive a letter from one of their developers about a problem with PalmOS 5. Twenty Four hours later another E-Mail posted with a message of a trial version. The program ran like a champ. I love the windows and the data. Nice number of star and object catalogs. It will be nice if it could support high resolution modes in the T3, but this will not stop me from giving them the ***** they deserve. Keep on the good work.

WOW! This is good stuff. I spent a few minutes outside last night with my backlit palm. In a few seconds I had found Orion on my handheld and in the sky. From there I was able to identify Jupiter and Saturn, as well as the obscure names of many other stars. The graphics are fast and easy to navigate. The information provided about each stellar object is pretty comprehensive. The only quibble I have (and this is surely due to my own ignorance) is that it may be difficult to find the common name of a star, given the way the included star catalogs are presented. For example, the north star, polaris, is listed as (I think) "UMi: Yilduz Alp". So if you search for "north" or "polaris" or even "alpha ursae minoris", you would come up empty. A little digging into the nomenclature reveals that UMi is shorthand for Ursa Minor. So most stars are sorted by constellation, which is pretty handy. It would be nice if the silkscreen search button brought up the internal Astro Info search rather than the generic Palm database search. Overall, this is a delightful piece of software.
