I feel like worn devices like fitbit and apple watch can do the same?

Even my breathing is depressed 😔

This article is very inaccurate.

1. Nowadays you can do a sleep study at home with a minimally intrusive wrist band type device. You don’t need to be in a sleep lab.
2. The “pill” doesn’t measure oxygen sats/desats, and I doubt it ever will. This make it useless for diagnosing sleep apnea.
3. Swallowing a pill seems more invasive to me than wearing a watch-like device, which is almost what’s currently used today.
