Health Tech Reviews: Smart Rings, Sleep Tech, Scales and Monitors, Checked Against the Evidence

Health gadgets promise a lot: better sleep, a clearer picture of your heart, an early warning about blood sugar. Some of them deliver, some measure less than the app suggests, and a few are worth buying only if you will act on what they tell you. This is where DailyStoke reviews them, with prices checked in the UK and claims set against published studies rather than marketing pages.

None of it replaces your GP. Where a reading should send you to a doctor or a pharmacist, each guide says so.
