Polarsteps (Android & iOS)
You can feed the app with hotels, restaurants, and other places you have visited, including photos and videos. This lets you relive the trips on your smartphone. In addition, there is a statistics tab that would love to be fed with relevant information, lending a somewhat addictive slant to it.
You can also plan your upcoming trips and not only receive curated information about the destinations you’re headed to, but you can also have recommended routes that take various travel options into account. You can decide at any time if your trips can be seen by the public, for your friends only, or to be seen by your eyes and nobody else. You can follow other users and share your trips across various platforms. This lets you create your very own travel social network.
The entire app is free and has no pesky advertising and in-app purchases for you to deal with, although it requires an account. If you’re up for it, you can also have a travel photo book made from your trips. It’s cool that the app can also be used offline. Another neat trick is the ability to optimize the app to minimize battery consumption while using the app.
