Packr Travel Packing Checklist is a free iPhone app developed by Jeremie Leroy. It is a travel and navigation app that helps you pack your suitcase for each trip. The app creates a packing checklist based on your destination, travel dates, and activities.

The app features 24 pre-defined activities, and your packing list will be ready in no time based on the length of your stay, weather, and planned activities. Packr learns from each of your trips to organize the packing checklist and adjusts the items based on your previous trips. Users can set a quantity for each item, and some items' quantity will be automatically adjusted to the length of your stay. Premium users can synchronize trips on all devices and share the checklist with travel companions or print it out.
