How is this different from a regular neck fan?
A neck fan moves air across your skin — it changes how you feel, not what’s actually happening inside your body. APEX uses AI-powered dual-Peltier tech to actively draw heat away from your neck, engineered to bring your core body temperature down by up to 2 °C. Skin-deep cooling feels nice for a few minutes; core cooling is what actually keeps heat strain from building up.
Does it actually cool, or does it just feel cold?
It’s real heat transfer, not a menthol or evaporative trick. APEX’s AI-optimised dual-Peltier modules physically move heat away from your body, cooling roughly 450–650 ml of blood every minute as it passes through your neck. That’s why the effect holds up over hours, not just the first few minutes.
Do I need to switch between cooling and heating, or does it happen automatically?
It’s fully automatic. APEX has sensors embedded directly in the device that read your body’s data every second. The only thing we need from you upfront is your weight, entered once in the app — from there, our AI algorithm continuously analyses your sensor data and automatically optimises the Peltiers, switching between cooling and heating in real time. No buttons, no manual switching, no app checking required once you’re set up.
How long until I feel a difference?
Most users notice a shift within the first 2 minutes of wearing it. Full effect builds as the device reaches steady-state cooling, typically within 5–10 minutes depending on ambient temperature and activity level.
What does the biomarker tracking detect, and what should I do if it flags something?
APEX is engineered to protect you from heat exhaustion and heatstroke with 99.99% protection. It gives you an edge — tracking 9 biomarkers in real time — and if we detect any unusual readings, you’re notified early on cardiac, blood-pressure and cognitive health risks, giving you time to seek medical care before things get serious.
Is my health data private?
Yes. Your biomarker data is encrypted and stored securely, and it’s never sold or shared with third parties. You control what’s stored and can delete your data at any time through the app.
How long does the battery last, and how fast does it charge?
APEX runs up to 8 hours on a full charge, with 2× fast PD charging to get you back to full power quickly between uses.
How much more cost-efficient is it than conventional wearable ACs?
APEX is up to 10.9× more cost-efficient than conventional wearable ACs — delivering better active cooling benefit at a fraction of the cost to own and run over time.
