Sleep trackers everywhere: How does one choose?

With the growing number and variety of wearable sleep tracking devices in the market today, users are often unsure which one best fits their needs. Commentaries by consumer facing reviewers often look at features that researchers or clinicians treating patients do not. The latter are influential, but because they predominantly face persons with sleep complaints and not those who are mostly healthy, the goals of the latter—to self-understand sleep and maintain or improve it—tend to be submerged by technical concerns that may not be relevant.
