Well, everyone probably knows Google Maps. But I don't use any other app on my travels as much as this one! On the one hand, I use Google Maps for navigation - both by car and by public transport or on foot. On the other hand, I use it as a planning tool. Before our trips, I always save places of interest, restaurants, cafés and more in Google Maps lists - or I spontaneously check out what good places are nearby.
When I click on my saved lists, I have an overview of where all the places are and how we can best plan our route. For further route planning - at least on our road trips - I also use the Google Maps navigation function, which not only allows me to search for routes from A to B, but also to add stopovers. This makes organizing routes so much easier! The app also has an offline map function. This can be particularly helpful if you're traveling without internet - like we did in Jordan, for example. All you have to do is download the desired map section before your trip and you can access the map in the app at any time.
By the way: I always create a Google Maps list with the most beautiful places after every trip to make it easier for you to plan your travels. I provide the lists free of charge and link to them under every blog post.
