I'm OK for friends and family app for iPhone and iPad

Im OK for family and friends is designed to be a basic, simple to operate app where the user can set up up to three recipients to receive SMS messages from the user. By tapping Im Ok , the app prepares an SMS to the users nominated recipients stating Im OK. The message is sent after user confirmation.
In the event of the user tapping I Need Help, the app will prepare an SMS including Latitude and Longitude and a map link (when available) of the users location to the recipients stating the user needs help. The message is sent after user confirmation.
If the user does not send the message by a user pre-determined time the day following their last message being sent, the app will generate an alert message to the user reminding them they have not sent a message. (This feature can be turned off)
This download of the app will cease to operate after seven days. At this time the user will be given the opportunity from within the app to upgrade to the Premium Version using the App store for a One-off Tier 3 transaction which will remove the seven day restriction. The user can upgrade prior to the seven days expiring if desired. If the user changes devices or re sets up, the app can be restored at no additional cost.
