People love to travel and people love to save money. But often these two don’t go hand in hand. Budgeting for travel can be tricky as you often tend to underestimate or overestimate the travel expenses and in both cases, you could lose money.

Thankfully, digital innovations in the travel industry gave rise to thousands of travel apps that not only ease your stress in planning the travel, but also help you save money.

Here are some of the top travel apps to consider on your next trip.

1. KAYAK

Whether you know exactly where you’re going and need a ticket, or you’re just looking to escape to a random destination, KAYAK is one of the most robust flight comparison tools. In addition to flights, you can also book hotels and car rentals at the best available price.

Keep an eye on the Price Forecast tool of KAYAK uses data from over a billion annual queries to anticipate whether airfares will rise or fall in the coming week. It also suggests package deals where you can save up to 32 percent by choosing a flight and hotel package together versus booking them separately.

You can also set price alerts on your desired route and let KAYAK do the grunt work for you by finding the best deal for you. If you are not connected to the internet it notifies you via text or email as soon as the hotel prices or airfares change.

2. GasBuddy

If you want to find the cheapest fuel prices in your vicinity, GasBuddy is the go-to app.

When travelers use the app to pay for gas at stations that accept payment using GasBuddy, they get a discount of $0.10 per gallon for the first fill-up and $0.05 for every gallon pumped after.

Another cool feature is the Gas Price Chart, which you can customize by destination to see the fluctuation of gas prices in the past 18 months, as well as the Trip Cost Calculator, which shows you how much you will spend on gas by entering in specific details, like your car's year, fuel type, tank, and more.

Keep an eye out for additional seasonal and station-specific promotions throughout the year to save even more at the pump.

3. Getaround

Getaround is a car-sharing application that lets you rent out your car whenever you’re not using it. Simply put, Getaround is like Airbnb for cars.

Getaround claims that car owners can earn up to $10,000 a year through this app, depending on the type of car they own and how often people rent it. Check out the process of enrolling your car for rent in their owner's manual.

Getaround rental rates start from as low as $4 per hour which is one of the cheapest options available when it comes to short trips. Checkout the renter's manual for more information on renting.

Using Getaround is a win-win for both the car owner and the renter in terms of saving money!

4. HotelTonight

If you’re one for spontaneous adventures and saving money, then HotelTonight offers the perfect solution by loading up last-minute deals of hotel rooms that are still available.

Every time you see a hotel that has a GEO RATE or HT PERKS badge, you get an extra discount to use on that booking. Or you can exchange it for credit to put toward a future stay at participating hotels.

For example, say you decide not to use the $40 discount on your next booking and save it for a future booking–do that five times and you'll have $200 in Save for Later Credits added to your account to use for a fun future stay. Also, Save for Later Credits never expire.

HotelTonight is available in 1,700 cities and with a database of more than 50,000 properties so you can always get the best deal for an entry-level room or a suite.

5. Hopper

Hopper is a flight-watching app that tells you roughly how much flights will cost in a nicely laid-out calendar view. You can set alerts and watch flights for when the price goes down.

You can also use Hopper to gauge how much a trip will cost and when they predict prices to rise or fall. Hopper's calendar view makes it easy to see when flight prices are generally higher and lower for your destination.
