The Apple Watch's daily recharge requirement is a significant hurdle for long-term health tracking, especially when compared to smart rings and screenless bands that offer week-long battery life. This limitation is a missed opportunity for Apple, as it hinders the device's ability to provide valuable health insights, particularly in sleep and ovulation tracking. The author argues that Apple should consider developing a smart ring, leveraging its existing health infrastructure and expertise in miniaturizing sensors. While Apple has flirted with the idea of a smart ring in the past, concerns about cannibalization of Apple Watch sales have been a barrier. However, the market for smart rings is growing, and Apple's recent acquisitions of Oura and talent from the health tech industry suggest a potential shift in strategy. The author concludes that while Apple may focus on improving the Apple Watch's battery life in the short term, a smart ring could be a valuable addition to their product lineup in the future.
