The biggest hurdle: Users must proactively share data. For @sleepagotchi to build AI Wellness, user data is an extremely important asset. But sleep data is not like social media data; users need to wear the wearable and maintain the habit for a sufficient amount of time. Apple Watch, Oura, WHOOP, and Fitbit are all part of their own ecosystems, so Sleepagotchi depends on the access permissions of each platform. Simply turning off permission or stopping wearing the device can interrupt the data flow. The next issue is consent: the more health data collected, the higher the demands for privacy and transparency. Therefore, Sleepagotchi's challenge is not simply Data Collection, but Data Continuity + User Trust. To build long-term AI Wellness, they need to transform data sharing into a clearly valuable experience for users.
