McDonald's is treating us all to a free cheeseburger to help us through the difficult time before payday.

Anyone with the McDonald's app will be able to claim their tasty snack.

All you have to do it download the app on Google Play or the App Store and get down to your nearest restaurant.

The offer opened today (January 21) at 10.30am so just get that app downloaded, locked and loaded for free cheeseburger joy.

The app enables customers to order, customise and pay for meals before arriving at the restaurant.

Better yet, the offer is valid for five days, so even if Monday isn't your cheat day you have time to redeem it.

So...what are you waiting for?
