Other views give an hour-by-hour forecast for the next 24 hours, a satellite radar view of your current location, and a list of the prospects for people with various conditions (arthritis, allergies, sinus problems) and for various events (running, holding a barbecue, flying kites). It's like being a meteorologist without going to weather school.

Fairly unobtrusive ads slide open across the bottom whenever you change views. A $1.29 premium version removes the ads if you find them too annoying, but chances are you don't spend enough time obsessing over the weather for that to be an issue.

Got an important business dinner coming up? OpenTable lets you make instant reservations at participating restaurants without ever having to call (and hoping the maître d' can hear you over the restaurant's din).

Using your GPS location (or a location you enter manually) and the mealtime and party size, OpenTable finds nearby restaurants that are taking reservations for that time. Pricing information, menus and customer reviews from OpenTable's Web site help you choose a restaurant, and a map helps you get there.
