Addappt, a re-imagined address book for your iPhone, is releasing a major update today. Users will now be able to “shake to call” from within the app, along with receiving badge notifications, international support, and more.

“Living” address book addappt has just recently been updated, moving up to version 1.5 and adding a number of handy features. Probably the most unique addition is a “Shake to Call” option. Users can select one phone number and then call it anywhere from the app by just shaking the phone. To select the number, go the contact’s page, select the “More” icon to the left of the name and then tap the “Shake to Call” icon.
