IFTTT Launches iPhone App for Automating Photo, Contact, and Reminder 'Recipes'
For example, a user can arrange for a photo taken with their iPhone to be automatically uploaded to their Flickr account or the service can be set up so the user is texted the weather report each morning in addition to whatever other "recipes" users can cook up.
The app currently allows interactivity with the iPhone's photos, contacts and reminders, but IFTTT says that "this is only the beginning", hinting that more features taking advantage of the hardware are likely to make their way into the app in the future.
IFTTT for iPhone is available in the App Store for free. [Direct Link]
