The vision of precision medicine is to provide the right intervention to the right patient, at the right time and dose. The described approaches, based on iterative feedback between the developers and the clinical end users, could increase our ability to adapt stratification algorithms better to new insights in disease biology, access to new molecular data, and changes in clinical settings. This has been a challenge with promising predictive models often failing validation in independent studies. Real-world longitudinal data from clinical practice and data collected through wearables or other means of participatory data collection cannot only widen the spectrum of possible data sources to build new stratification algorithms [52, 53], but they may also be partially included in clinical trials for validation purposes of stratification algorithms.
In 2021, Google announced the new version of its wearable operating system, used by such tech and fashion brands as Mobvoi, the Fossil Group, and Samsung. It's called Wear OS 3, and it was co-developed by Google, Samsung, and Fitbit (the latter is now Google-owned). As we've seen on the Samsung Galaxy Watch4 and Watch5, it delivers better performance, longer battery life, and includes more third- and first-party apps, along with robust health and fitness improvements.
