Restaurant/Fast Food Apps with the best discounts and rewards?

I've gotten a lot of free stuff and great discounts over the last year using restaurant apps and wondering if anyone has recommendations on some good ones?

I use the Arbys and Sonic app a lot and they have pretty good discounts almost every day. I've gotten a ton of free food from McDonalds but I'm completely tired of it so I am taking a break from McDonalds for awhile.
