If you’re anything like me, checking out of a hotel means scouring every inch of the room to make sure you aren’t leaving anything behind. However, even after inspecting closets, drawers, and practically everywhere else I could’ve left something, I’ve still somehow managed to forget everything from a phone charger to a pair of sunglasses.

Though when you’re already busy enough thinking about pressing matters like if you’ll make it to your flight on time and how much it’ll cost to fill up the gas tank of your rental car, a bit of oversight is to be expected. Unless you’ve got PackPoint, that is.

Praised by a range of publications from the Los Angeles Times to Lifehacker, PackPoint is a handy travel app that aims to optimize the packing process. With PackPoint, you won’t ever have to worry about forgetting to bring flip-fops on vacation or returning home without your toiletry bag.

The way PackPoint works is simple. To begin, input your gender, where you’re planning to go and when, the nature of your trip, and some of the activities you plan to take part in while you’re there. Once you’ve provided PackPoint with this information, the app will compile a list of clothing, toiletries, gadgets, accessories, and other things you might want to consider taking along with you.

Interestingly enough, PackPoint even takes the weather forecast at your destination into consideration and recommends additional items accordingly. This saves you the extra step of having to look up what the weather will be like during your stay.

Once PackPoint has generated a packing checklist, users can select the items they are planning to bring, as well as deselect the ones they don’t. You can also manually add anything to the list that PackPoint might’ve forgotten. I mean really, how can you expect it to know that you never travel anywhere without your lucky baseball cap?

After you’ve personalized the list to your liking, you can save it for future trips as well as share it to friends and family you’re traveling with via text message, email, Twitter, and Facebook.

With its user-friendly interface and variety of features, PackPoint is a free app that you can’t afford to travel without. Before you start packing for your next trip, download PackPoint and see what a difference it makes.
