Swiss outdoor manufacturer Mammut Sports Group AG has developed an iOS app primarily for recreational use called the Packing List. Best of all it’s free.
The Packing List app is designed to help you pack for a variety of high adventure activities like climbing, mountaineering and snowshoeing. Although each list template is assembled by the pros, you can customize it or even create new packing lists. What’s more, you can invite team members to share your list for collaborative trip planning and add new items not already loaded into the app.
