T.G.I. Friday’s is offering a free appetizer if you download the restaurant chain’s mobile app.

Go to www.tgifridays.com/mobileapp for information about the deal and links to sites where you can get the app for iPhone or Android.

The app is free and you’ll get your free appetizer coupon in the “happenings” section of the app, the T.G.I. Friday’s site says. The coupon is good for a free appetizer worth up to $8 at participating locations.
