Where to Archive Your Tweets
Both of my apps — Tweet Library for iOS and Watermark for the web — can now import the .zip file you receive from Twitter. This file contains your full archive of tweets and retweets. Both apps can load the file directly from Dropbox, making it as simple as possible to get the tweets imported. And both apps are smart about only importing tweets that haven’t been stored yet, so you don’t have to worry about duplicates.
