Stranded? Under the Weather? Just need a driver?
iNeedaRide allows you to send an emai and/or an SMS message to two standard contacts and anyone in your address book. The content of the message is a link to a map page which will allow the person to whom the message is sent to get driving directions to your location.
You can enter Primary and Secondary contact information and it is stored within the app. Then just click the "iNeedaRide" button and send and email and/or an SMS message automatically to those people. You can add addition recipients in either the email interface or the SMS interface which is presented.
