AppAdvice has teamed up with Enabled Apps in order to offer you a chance to win one of 10 promo codes for TripList ($2.99) for iPad.

Whether it’s a vacation or business trip, there are numerous items we need to organize and pack, plus tasks to complete before a trip even begins. This includes everything from booking hotels and flights to making certain our iPhone, iPad, and MacBook are fully charged before heading out.

Most of us don’t perform these preparation tasks far in advance, except booking a flight and hotel. In fact, the packing process usually consists of going from room to room and selecting items deemed a necessity at the seemingly last moments. Unfortunately, this method can result in lots of forgotten items.

Designed by a frequent traveler, TripList allows management of multiple trips for multiple travelers through a simple but thorough checklist system. Lists are organized by category with the convenience of predefined items available to choose from. In addition, you can customize the default item and task catalog, backup and restore via Dropbox, and import from a TripIt account.

You can learn more by reading our earlier TripList for iPhone review and trying the free version of TripList.
