Dopplr is an online tool for frequent travelers. The idea is simple. You enter your travel details, city, dates, description and you can share that data with your fellow travelers and friends.
Adding a trip is easy. Just fill in the destination. You can use place names, airport codes or even postal codes, and Dopplr will try to figure out where youâ€™re going. The database of place names doesnâ€™t include everything, but itâ€™s quite comprehensive. Then click the start date of your trip. A calendar will pop up (or down) to let you select the day (2) you plan to arrive in the new place. Then fill in the finish date the same way and add an optional note describing why youâ€™re taking the trip. This note will be visible to people you share trips with.
