Diver Alert

Iphone app similar to 'Overdue' on android. I have not found any other similar apps in my search. This app is for scuba divers who go on dives but do not let people know where they are or when they will return. Diver has their personal details, and emergency contact details in the app and the provisions to add details of a dive buddy who is with them. When going on a dive the diver enters their location ( app will get gps coords for location), buddy details, vehicle details, time of start of dive and estimates return time. 15 minutes after the entered return time an alert appears on the divers phone asking them to acknowledge their return and cancel the alert. If the alert is not cancelled within a further few minutes the alert is then sent to the emergency contact via sms or social media messenger. The emergency contact can then access details of where the dive was. They then attempt to contact the diver direct to see if they are ok or forward the details to emergency services to initiate searches etc. The details available to the emergency contact and emergency services will include Diver and buddy details, GPS coord location of dive, car registration details to help identify a car left in a carpark or boat details, time of water entry and estimated arrival back. This app could be useful for scuba divers, snorkelers, or anyone else undertaking adventure sports/activities where they may be in isolated locations and they want people to know where they are. It is not designed to link with dive computers etc to log details of the actual activity, purely to alert someone should they not return at a designated time.
