A
Road Trip Apps
RoadWarrior
Ever wonder how delivery drivers manage to hit so many different places in a relatively short amount of time? It’s because they’re using an app like RoadWarrior to plan their routes (路线) to be as good as possible. However, while many other route planning apps only take things like traffic into account, RoadWarrior includes lots of other time-wasting details.
GasBuddy
Gas prices are high at present, so travelers are naturally focused on finding the lowest rates whenever possible. GasBuddy is one of the most popular apps for finding affordable gas, especially on long road trips. Like many apps, there is a free version (版本), as well as a paid version with $10 per year for added features.
RoadTrippers
For people who aren’t totally focused on getting from point A to point B in the fastest time possible, the RoadTrippers app is a must-have. Users can plan their trip from start to finish with as many as 150 stops for them to choose from along the way, which costs $29.99 per year. It won’t let you miss the famous scenic spots. It tells fuel costs, allows for drivers to plan friendly routes to their particular vehicles and lets the users cooperate (合作) with friends who are also on the road.
HotelTonight
Travelers sometimes don’t know exactly where they’re going to be at the end of the day, so they can’t book the hotels ahead of time. Fortunately, there are apps designed to help travelers get cheap last-minute hotel deals. One of the best is HotelTonight, which allows the users to search for the hotels available tonight in a given area at a low price, and it includes additional discounts.
