If you love to cook, you can add the Foodily app to your timeline and share your latest dishes. If your friends have added the Foodily app, you can discover new recipes with each other, as you'll see their updates in the ticker and their timeline, and possibly News Feed.

If you're a traveler, you can add the Gogobot and TripAdvisor apps to bring a virtual passport to your timeline, and show your friends where you've been and share tips about your favorite spots from around the world.

Soon, there will be apps for all types of interests, as more apps will launch over time. Whether you love snowboarding, gardening, hiking, or knitting, or something else, there will be an app for you.

How to add apps to your timeline

Timeline apps are for the activities you want to share with friends. You choose when to add an app, and you decide who can see it. After you've added an app, you can always remove posts directly from timeline, and you can also edit your settings from your personal Activity Log.
