Versatile by design

Wear it anywhere on your body.

Unlike typical smartwatches, ALVA Sense is designed to be worn three ways — optimise placement for the activity and the data you want.

Wrist wear

Wrist wear

Classic position for daily health tracking. Ideal for 24/7 monitoring of heart rate, sleep and blood pressure.

Arm wear

Arm wear

Ideal for intense workouts where you need more stable positioning and reduced wrist movement.

Leg wear

Leg wear

Great for running and cycling — leg placement provides more accurate stride and cadence data.

Women's health
Women's health

Understand your unique cycle.

ALVA Sense tracks your menstrual cycle through the companion app, combining body temperature data with cycle history to give you real insights about your body each month.

Cycle tracking

Log your period and let the app predict your next cycle, fertile windows, and PMS days based on your own pattern.

Temperature & hormones

Continuous body temperature monitoring detects subtle changes linked to ovulation and hormonal shifts.

Pregnancy follow-up

Switch to pregnancy mode to track relevant health metrics week by week throughout the pregnancy.

FAQ

Frequently asked questions

How does the ECG work?
ALVA Sense has a physical ECG button on the side of the band. Press it, stay still for 30 seconds, and the band records a single-lead electrocardiogram. The result appears instantly in the companion app — you can view the waveform and export it as a PDF to share with your doctor. Note: ALVA Sense is a wellness device, not a medical diagnostic tool.
How long does the battery last?
In standard daily mode ALVA Sense lasts 20 to 30 days on a single charge. If you use ECG, blood pressure and sports tracking frequently throughout the day, expect 5 to 10 days. Charging takes approximately 2 hours via the included magnetic USB cable.
Is the strap adjustable? Will it fit my wrist, arm or leg?
The band uses a 22mm nylon braided loop strap (26.7cm long) with a hook-and-loop closure, so you fine-tune the fit yourself instead of picking between fixed holes — it comfortably fits the large majority of adult wrists, forearms and calves. If you have an unusually large wrist or arm, the strap may sit at its outer limit; message us before ordering if you're unsure and we'll advise honestly.
Which app do I need and is it free?
ALVA Sense pairs with a free companion app, available on the App Store and Google Play. There is no subscription and no ads. The app is available in 40+ languages including English, Spanish, French, German, Italian, and Portuguese. Full setup and pairing instructions are included in the printed quick-start guide in the box. It shows your full health dashboard: ECG, blood pressure, temperature, sleep, body composition, cycle tracking and sport sessions — all included at no extra cost.
Is it water resistant?
ALVA Sense is rated 1 ATM — it handles rain, splashes, sweat and hand washing without any problem. It is not designed for swimming or submersion. We recommend removing it before swimming or diving.
Does it have an SOS button?
Yes. Press and hold the physical button on ALVA Sense to send an SOS alert to the emergency contacts you set up in the app, at any time. Requires internet connectivity on the paired phone to send alerts.
How long does shipping take?
Orders ship within 24 business hours. Delivery to Spain takes 2–5 business days and to the UK 4–7 and to Ireland 4–13 business days. Other international orders typically arrive in 6–13 business days, depending on the destination country. You will receive a tracking number by email as soon as your order leaves our warehouse.
