I lived in Seattle for three years. The city is great, and the people are even better. I used these apps when I lived there!
Seattle Weekly Free
This is the app for the Seattle Weekly. It has a comprehensive restaurant guide sorted by location and cuisine, an events calendar, articles on local events and places, slideshows, a nightlife guide, and more. Very useful!
Seattle Dog Park Finder
This app lets you look at Seattle off-leash dog parks on the phone. You can search by name, see more info on the hours and rules for each park, and see the park on a map.
Travel Seattle 2011
This is an extensive travel guide for Seattle that costs $9.99. It has not just current things like nightlife, dining, lodging, and attractions – but also lots of info on culture and history of the area. Very comprehensive – the only guidebook you’d need!

This free app has news, photos, video, and more for West Seattle and beyond. Nice UI, good for keeping up on local news.
