Together is a mobile app designed to help cancer survivors transition between healthcare providers and treatment stages. Version 1 will be released for iPhone in August and focuses on facilitating communication between survivors, caregivers and providers through a secure "Care Conversation". It was co-designed over 6 weeks with input from survivors, caregivers, providers and experts to create an intuitive interface addressing key pain points around care coordination and transitions. The app leverages cutting edge design, security and data integration to provide a HIPAA-compliant personal health record and enable sharing of sensor data from devices.
