Cairns Health has acquired AI app Together by Renee and will fold its medication tech into Luna to support older adults and people with chronic conditions.
Together by Renee uses computer vision (software that reads images) to scan pill labels for reminders and refills, and “agentic” AI (systems that act toward a goal) to automate tasks. Cairns said the app will be integrated into Luna, its voice-based companion for older adults.
“Our goal with Together by Renee was to make healthcare radically easier, not just smarter,” said Nick Desai, chief executive of SixD Inc. “From managing medications with a single photo to automatically refilling prescriptions with voice AI, we built one of the earliest examples of agentic AI in action. We’re excited to see this innovation continue under Cairns’ leadership.”
The app has grown to more than 50,000 users and has over 1,500 five-star ratings on the Apple App Store. It remains free on iOS and Android. Financial terms were not disclosed.
Cairns plans to add Together by Renee’s features to Luna over the next six months, enabling voice-driven care such as medication reminders, symptom checks and physiological health monitoring (tracking vital signs). The aim is to improve adherence and reduce burden on patients, caregivers and care teams.
“We’ve been exploring technologies that complement our Luna digital care companion for seniors and those with multiple chronic conditions, and the vision Nick and Renee built with Together by Renee was a perfect fit for mobile vision,” said Andrew Ritter, chief executive at Cairns Health. “Its ability to help users manage medications by scanning a label is game-changing. By bringing that technology into Luna and layering voice capabilities on top, we can now talk to users, help them stay on plan, and take a complex healthcare situation and transform it into a simple conversation.”
Cairns said the acquisition also supports users in senior care communities and will underpin a consumer-facing release later this month to help caregivers manage loved ones remotely.
“This deal allows us to take Luna beyond the bedroom, supporting patients wherever they go 24/7,” Ritter added. “Loved ones, caregivers, and provider organisations are now all on the same tech stack in a true care team approach, making it easier to communicate, monitor and deliver the right care at the right time.”
