Hi there -
We have the My Diet Diary app for Android. It is available at no cost in the Android Market.
Currently, it won't be able to sync your tracker here and what you input in the app, but we will be offering that in an update within a couple of weeks. We will also be adding the feature to add your own phone at that time. In the meantime, if you add it to your tracker on the site, it will add to the database, so you will be able to find it on your phone.

Please let us know if you have any questions.
