More than 37 million Americans are hitting the road this Memorial Day weekend. If you're going to be one of them, download these apps to your smartphone or tablet to help you save time, money and just make for a more fun and pleasant drive.

Waze (free, iOS, Android, Windows Phone)

Even if you already have GPS, you'll want this navigation app -- especially during a busy weekend when traffic is thick. Waze offers real-time trafffic updates, gas prices, alerts about speed traps, and multiple route information. Owned by Google, the app is based on data coming from other drivers on the road. And it works surprisingly well -- it’s consistently voted one of the best navigation apps for saving drivers time.

GasBuddy (free, iOS, Android, Windows Phone, BlackBerry)

This is another app that uses crowd-sourced data to let you know where the cheapest pumps are in whatever area you’re in. Prices are updated in real time. (free, iOS, Android)

This new app offers access to roadside assistance -- no membership fees required. If you run into trouble on the road, use this app to connect service providers who can help you get back on your way. You pay a flat-rate, per-use fee for the service. The developers are still rolling out destinations around the country -- check the web site to see where service is currently offered.

Glympse (free, iOS, Android, Windows Phone)

Visiting friends or family? This app shares your current location in real time with the people you specify. Your loved ones can keep track of where your are -- and your expected time of arrival -- without you having to call or text them while driving. And don’t worry: You specify the destination and duration of the tracking info -- and who has access to it.

TVFoodMaps (free, iOS, Android)

Skip the chain restaurants and use this app to find all the restaurants featured on TV shows like Diners, Drive-Ins and Dives. You can search spots by location or show, set up alerts so you’re notified when you’re driving near a featured restaurant and more.

This iPhone app looks for restaurants, coffee stops, landmarks, parks, rest stops and shopping options along your route while you’re driving.
