Flight Tracking/Notification Using ADS-B

Anyone know of an app that uses ads-b to send flight tracking and notifications of your flight to friends and family? I know about FlightAware and FlightRadar24. They offer only limited features. I would like to duplicate the features that SPOT offered where you can send text notifications to family (I.e. my worried wife) which alerts them when I?m in the air and then let?s them track my progress. I?ve stopped using SPOT because it interferes with my GPS signal. But there?s got to be a ?SPOT Like? app that works with your ADS-B out data.
