Android/iOS: No one wants to spend $20 on a sandwich, but when you're hungry and want something more than a tiny bag of nuts, you surrender to expensive airport food. If you're travelling through the US and in a rush, Grab is a free app that pre-orders this food for you so you don't have to worry about a missed flight.
The app gives you a list of eateries you can order from, depending on the airport (only US airports, though). It also maps out these spots so you can make sure they're actually in your terminal and, ideally, already on the way to your gate. From there, Grab works just like any other food ordering app: Pick a place, order and pay. Your food will be ready once you get there and you can skip the lines.
As for security, they partner with Braintree, a Paypal company, and they don't store your information on their servers. You can read their full policy here.
It's a useful app if you travel frequently in the US and find yourself short on time. It even comes in handy if you just want to explore food options before you head to the airport. To check it out for yourself, head to the link below.
