Issues with App
This criticism is directed to the App, not the actually food. The App use to be easy to you, and could order straight from it. Now when placing an order it sends you to a website, and if you want to use your account you have to sign up now with another company “toast”. Just seems unnecessary when the app was working perfectly previously.

Can’t customize ALL ingredients in the app.
Love the burgers, but the app won’t let me customize certain ingredients, specifically I can’t get order my favorite burger without Mayo. Ridiculous. I’ve sent feedback a few times to try to get it changed. This last time they just ignored me.
One of worst app
I have no idea how customers are supposed to use this app. It’s very hard to figure out. I received a notification about a special offer, but there was nothing related to that offer in the app. It’s also difficult to understand how the rewards work. Overall, the app is useless.
Can’t get burgers without mayo
Recently Killer Burger changed the menu to add mayo to nearly every burger, but the app does not reflect that change. I hate mayo, but I cannot get my order without it using the app so I have to call or order in person. This makes the app useless to me. I’m leaving this bad review in hopes that they finally fix this issues because it has persisted for months. Please fix it. I love the food there, but not mayo.
