Whether you're moving to San Francisco for school or work or vacation, it's helpful to learn the lay of the Bay. The 7x7 city is built on a grid, but two of its main thoroughfares -- Market St. and Columbus Ave. -- confuse things by running on a diagonal. And then there are the one-way streets. So how do you get around, and what should you wear while out and about?

You'll never be appropriately dressed unless you layer, since the weather here changes at least three times per day, alternating between chilly and foggy, humid and gray, and warm and sunny.

Seasonally, it's hot when it should be cold and cold when it should be hot in most other regions of the country. Not to mention the fog (which locals call Karl the Fog) appears at the most inopportune times, like when the July 4th fireworks are underway.

Finally, with so many new eateries opening and closing in this restaurant capital and so many events to explore on a daily and nightly basis, how do you know which ones to choose?

Whether you're a tourist or a new resident, these apps will help you live like a Bay Area local in no time.

Where to stay

Airbnb (Android, iOS)

Anyone can stay in a sterile hotel room devoid of local flavor. If you want to live like a local, book a room, apartment, or entire vacation home with Airbnb. The rates are often a fraction of the cost of a hotel room, and you can also book local travel experiences within the app, such as historic Victorian home tours, urban farm visits, or silent disco beach yoga. If you're lost or have any issues, Airbnb offers directions and a messaging feature to contact your host.
