Some of you may use
Evernote, software designed for syncing notes across computers, phones, etc.
There is also
Evernote Food, which is designed for "preserving your food memories". I just downloaded it for my iPhone (there is also an Android version) and haven't played with it very much yet. The basic idea is that you snap pictures of a dish, ingredient, etc. and the app makes it easier to record where you were, when, etc, and then sync it across devices.
