Find the Right Health Tech
for Your Goals

GreatHealthGear is an independent research-based review site covering health and fitness technology. We evaluate sleep trackers, smart scales, massage guns, red light therapy devices, cold plunge equipment, sauna blankets, recovery boots, EMS and TENS devices, and breathwork trainers — with coverage growing as the evidence base in each area matures.

Our editorial model is aggregation, not hands-on testing. Every score on this site is built from peer-reviewed accuracy studies, independent laboratory measurements, manufacturer specifications, and verified long-term user data. We do not accept sponsored content or free products in exchange for reviews. Affiliate commissions, when earned, come only after a recommendation has been made on its merits.

Each category uses a fixed seven-point scoring framework calibrated to the metrics that matter for that device type. The overall rating is calculated automatically — never set manually — so you can compare scores across our entire catalogue with confidence. Where evidence is preliminary or marketing claims outpace the research, we say so directly.
