The Challenge
Most health coaching apps gave every user the same generic advice, whether they were a beginner or an athlete, and ignored the health data already sitting on their phone. Users wanted a real coach: a distinct voice and personality that actually knew their sleep, activity, and vital signs, not a chatbot reciting the same tips to everyone.
Generic AI health advice that sounds confident but isn't grounded in real science does more harm than good, so trust had to be built in from day one.
The Solution
New York App Devs built Decima's coaching engine around Apple HealthKit, pulling in sleep, activity, and vital-sign data to give each user a real picture of their health. Users pick an AI coaching persona, from a motivational "Drill Sergeant" style to a gentler tone, and the app talks them through it by voice.
The architecture was built to HIPAA compliance standards from day one, delivered ahead of the product's public launch.
