iFitness HD for iPad

This comprehensive exercise app is a very good fitness offering that sometimes tries to do too much and doesn't always measure up to its iPhone counterpart.

Phases HD for iPad

This app, which shows information about the moon, is nicely designed and takes advantage of the iPad's display capabilities. But what you see is all you get.

SoundNote for iPad

This note-taking app, which records audio while letting you type or scribble notes on your iPad, is not without its share of limitations. But it's also an impressive app that should interest students, workers, or anyone else who has to take notes during lectures, meetings, or presentations.

Weather HD and Weather Station Pro for iPad

Weather HD and Weather Station Pro have very similar aims: to turn your iPad into a simple virtual "weather station" that tells you the basics about current and future weather conditions in a visually elegant fashion. Each succeeds in its own style.

MindMeister for iPad

The iPad version of this mind-mapping tool lacks some of the features of the premium Web-based MindMeister offering. But for many users, the portability and power of MindMeister for iPad will be more than enough.

Hurricane tracking apps for iPhone and iPad

You can keep an eye on hurricanes from your iPhone, iPod touch, or iPad with the help of an assortment of App Store offerings. But which app should you choose for your storm watch? Jeff Merron rates five contenders.

Qrank for iPhone

Trivia games come down to how interesting the questions and answers are. And on that score, Qrank is a terrific game for your iPhone.

Easy Agenda for iPad

Usually, simplicity is a good thing in an iPhone or iPad app. But this personal scheduling app for the iPad takes the concept too far with limited features that will only appeal to users with the most basic needs.

Type n Talk for iPhone

This app, which repeats what you've type in a synthetic voice, is easy to use and works fine. The question is, what would you use it for?

Newsprint for iPhone

This bug-ridden RSS reader crashes and hangs frequently, often encounters "unknown errors," and is incapable of locating even the feeds that come preloaded on this $5 app.

Yellow Pages for iPhone and iPad

This useful app lets you look up information about businesses, including addresses, phone numbers, and, when available, a Citysearch star rating.

Popplet for iPad

This clever mind-mapping, brainstorming, and idea-collection app for the iPad has a few notable limitations. But Popplet's attractive interface and ease of use make it hard to resist.

Seasonality Go for iPad

This customizable weather app for the iPad takes a modular, graphic approach that's pretty appealing, though, in practice, its interface can be confusing and the graphic data overwhelming.
