Traveler apps: Dress for the weather

Swackett (free; iOS)

What it is: A weather app that uses icons to suggest what to wear based on conditions

How it works: Type in the city or postal code you're interested in to find hourly and daily forecasts, with highs, lows, "what it feels like" temps and wind speeds. Satellite motion imagery gives a hint of how weather systems are developing. That's when the iPhone is in landscape mode. In portrait mode, up pops a stylized human silhouette with a hoodie and shades when it's cool and sunny out.

Why it's great: Any weather app can give you forecasts, but the whimsy of Swackett makes it fun and informative. For 99 cents, you can dress your silhouettes in '50s togs.

Why you might hesitate: A tiny portion of screen real estate is devoted to ads (which can be banished if you pay 99 cents).

Who it's for: Anyone who wants to dress up their weather forecasts

Jetlag Acupoints ($2.99; iOS)

What it is: An assistant that reminds you when and where to apply pressure on your body in hopes of defeating jet lag

How it works: Enter your destination's time zone (a handy link is included to help you find what that time zone is) and tell the app how frequently you want to be reminded to apply pressure.

Why it's great: At two-hour intervals, the app reminds you to gently but firmly press a body part (with an image of the target body point and a dot indicating where to apply pressure) for two minutes while imagining you're in your destination at the current destination's time. For believers in acupressure, the app-makers promise you'll arrive refreshed and ready to go.

Why you might hesitate: At $2.99, this is a relatively expensive way to find out whether it will work for you.

Who it's for: Travelers who hope to rebound quickly from jet lag

Livestand (Free; iPad)

What it is: An attractive-looking reader that makes looking at Web content from Yahoo and other publishers feel more like you're looking at a magazine

How it works: Sign in with your Yahoo or Facebook credentials to swipe and flick your way through articles designed to feel like you're paging through a magazine. Most of the content — sports, financial topics, celebrity news, world events — comes from Yahoo, its bloggers and The Associated Press, with dozens of other publishers.

Why it's great: As many as four accounts can use one iPad, so four different personalities can bookmark different topics to receive continuous updates on whenever you're connected to the Internet. If you visit Yahoo often, Livestand is an easier, more elegant way to navigate Yahoo, with the bonus of having Consumer Reports, Parenting, popular blogs and other publications to subscribe to. You also can email articles and video to anyone or tap a button to view what you're looking at through a Web browser, so you can bookmark the content there too.

Why you might hesitate: You don't have complete control. According to Yahoo's online help guide, tapping a Quick Tune icon should have brought up similar articles to the one being read, but no such icon appeared. Quick Tune also supposedly would have adjusted what the viewer saw, but we'll never know.

Who it's for: Any Yahoo fan who wants an enjoyable way of perusing a preselected portion of the Web.
