Any of the life tracking Android applications that allow manual export and sharing of data files should include Quantimodo as a option on the share screen along with Dropbox, gMail, Google Drive, etc. This would be an easy way for people who don't have rooted phones to get their data in Quantimodo for integration and analysis. See the attached image for an example of what the sharing menu might look like.

Note that if you want to self-track with QuantiModo, but you don't want it to be present in the sharing menu, you could use this app to customize your sharing menu: http://www.cultofandroid.com/35276/customizing-the-share-menu-of-android/
