Here are some free Apps for touchpad
- HP App Catalog
The HP App Catalog, like other mobile app stores, lets you look at the most recent or most popular apps, as well as search by category.
- TouchPad App List
To find TouchPad apps in the App Catalog, look for the little gray words "For TouchPad" next to the name of each app. The last two apps in the list here don't have 'em; those are Palm Pre apps that can run on the TouchPad, but in a smaller window. You can’t scale them up to full size, like you can do with the iPad’s 2x button. - Angry Birds HD (Free)
In 2011, Angry Birds is the sign that your mobile platform has made it. Angry Birds HD for the TouchPad is smooth, free, and plays in full screen. If you become a real addict, though, you'll have to shell out $1.99 for Angry Birds Rio HD.
- Facebook (Free)
The TouchPad is only the second tablet with a dedicated Facebook app. And HP's app implementation is impressive, with several unique features, including this Flipboard-like full screen view of your news feed. A two-pane interface lets you flip easily between your news feed, messages, events, places, friends and photos, and the places where your friends checked in show up on a map.
- Amazon Kindle (Free)
What's a tablet without a Kindle app? There isn't much to the TouchPad's version yet, but it syncs with your existing Kindle library and lets you search for text, mark pages, and check your notes. There's also a link to the Web-based Kindle store, but when I checked it before launch, it wasn't working.
- Spaz HD Beta Preview 1 (Free)
Spaz was my favorite Twitter client on the Pre 2, and it's back on the TouchPad with a vastly expanded feature set. You can skim through multiple search columns, log in as multiple Twitter accounts, use different image hosting and URL shortcut services and, of course, Tweet. It's all the Twitter you'd want on this tablet.
- TuneIn Radio (Free)
Without Pandora, Slacker or Last.fm around, this is the best streaming music app for the TouchPad so far. TuneIn automatically gathers all of the streams for radio stations in your city, arranging them along a virtual AM/FM spectrum; if you want to go farther afield, you can browse a global directory of streams by topic.
- Typewriter Beta (Free)
An ingenious, and good-looking text processor for the TouchPad, Typewriter uses e-mail-like formatting conventions (for instance, “_italic_” and “[hotlink]” to create elegant documents. You can save your files to Dropbox, email them, or just save them on the TouchPad to transfer over later via USB. I'd like to see more features, such as spell check and find-and-replace, but this is a good start.
- Spaz HD Beta Preview 1 (Free)
So far the only weather app designed especially for the TouchPad, WeatherBug opens up with a virtual window showing you a recent picture of your location, which is pretty neat. Beyond that, you get forecasts, wind speed and direction, and radar images. Oddly, it throws traffic in there, too. WeatherBug uses the TouchPad's real estate well, but it's missing some of the more in-depth scenarios and advice you find on major weather sites, like recommendations on what to wear, allergy reports, or whether the weather is suitable for various activities.
