Pro tip — these are wellness trackers, not medical diagnostic tools. Consumer oximeters are great for tracking trends and curiosity, but readings can be affected by cold hands, nail polish, and movement — and they aren't a substitute for medical-grade equipment or professional advice. Warm your hands, stay still, and discuss any genuinely concerning readings with a doctor.
