Can a wearable measure my blood pressure or glucose without needles yet?
Not to a standard you should treat clinically. Wearables are good at heart rhythm, sleep staging and trends, and irregular-rhythm alerts have genuinely sent people to a doctor in time. Cuffless blood pressure is approximate and drifts; needle-free glucose remains unsolved despite two decades of confident announcements.

Screenshot-friendly summary — quote it anywhere, ideally with a link back.
What's possible today
- Regulator-cleared irregular heart rhythm notifications and single-lead ECG
- Sleep, respiratory rate and cardiovascular fitness trends
- Blood oxygen and skin temperature trend tracking, with caveats
What still can't be done reliably
- Non-invasive glucose measurement of any clinical usefulness
- Cuffless blood pressure accurate enough to manage hypertension
- Diagnosis of illness rather than flagging a signal worth checking

Privacy & risk considerations
- False reassurance is the underrated harm — a normal reading is not a clean bill of health
- Anxiety and unnecessary appointments from noisy alerts
- Health data sharing and insurer access vary by vendor and jurisdiction
What would need to happen next
- 01Sensors that survive independent clinical validation, not vendor studies
- 02Regulatory clearance for measurement rather than wellness trends
- 03Honest marketing about what is a trend and what is a measurement

Frequently asked
- Will a watch replace my finger-prick test?
- No. Nothing on sale measures glucose non-invasively to a usable standard, whatever the advert implies.
- Are the heart alerts real?
- The rhythm notifications are regulator-cleared in several markets and do find genuine cases — but they miss things too.

Have AI answer my phone calls
Can AI answer my phone calls yet?
Yes, mostly. Consumer phones and cheap call-screening services will pick up, transcribe and hold a short conversation with a caller, and they handle spam and simple appointment calls well. Anything nuanced — an emotional caller, a complex booking, a call that needs your judgement — still gets handed back to you.
Translate a live conversation
Can technology translate a conversation in real time yet?
Yes, and it is genuinely good. Phones, earbuds and some glasses translate spoken conversation with a second or two of lag across major language pairs. It is excellent for travel and everyday chat, and still risky for legal, medical or contractual conversations.
Have an assistant remember everything I tell it
Can an AI assistant remember everything I tell it yet?
It can remember a lot, not everything. Mainstream assistants now keep persistent memory of your preferences, projects and past conversations, and it noticeably improves them. Recall is still selective, occasionally wrong, and confined to whichever assistant you told.
