To give you the highest clinical accuracy, V-CHEK personalises its algorithms to your unique body. While the optical sensors measure the flow of your blood, everyone's vascular system is slightly different. By entering a single initial baseline reading, you "teach" the app your exact starting point. Once this one-time setup is complete, your device is tuned to you and you can enjoy frictionless, cuff-free monitoring moving forward.

Yes. For accurate measurement a smartphone is required. V-CHEK connects and syncs instantly via Bluetooth to the companion mobile app, where your data is processed, saved and charted over time.

V-CHEK uses state-of-the-art optical sensors to scan the blood flow beneath your skin using a method called Photoplethysmography (PPG). Advanced algorithms then analyse these pulse waves to determine your systolic and diastolic blood pressure, pulse rate and oxygen saturation.

Generally it takes around 60 seconds to complete a measurement of your vitals. If it is your first time it may take a little longer to stabilise; simply relax your hand and apply a gentle, steady touch to the sensor.

Battery life is around 60 days in sleep mode or up to 200 measurements on a single charge. V-CHEK features a long-lasting, rechargeable internal lithium battery. Charging takes 2 hours using the standard USB-C cable included in your box.

V-CHEK is clinically validated to provide highly precise, medical-grade readings. The technology has been rigorously tested against traditional mercury sphygmomanometers, with clinical results proving it accurate within ±3–8 mmHg for 93% of patients. Because the app personalises its algorithms to your vascular baseline during first use, it delivers this clinical-level consistency without the pain or squeezing of an inflation cuff.

Because V-CHEK uses highly sensitive optical sensors to measure micro-changes in blood flow, environmental and physical factors can influence your reading. For the best results ensure your hands are warm (cold fingers restrict blood flow), stay completely still and do not speak during the 60-second measurement. Readings taken immediately after exercise, caffeine or during stress will also naturally be higher.

We recommend re-personalising your V-CHEK profile if you experience a significant change in your baseline health, weight or medication. This simple reset keeps the algorithms tuned to your current vascular profile for ongoing clinical accuracy.

It is designed for convenient, regular home use: a compact finger sensor, readings in about 60 seconds and automatic logging to the companion app. For any concern about your readings, speak with a qualified healthcare professional.

Yes. The device weighs just 40 g, needs no cuff or pump and charges over USB-C. Battery life is around 60 days in sleep mode or up to 200 readings per charge.

No. V-CHEK is intended for monitoring purposes. It should not be used as a substitute for professional medical advice, diagnosis or treatment. Consult a qualified healthcare professional when you have concerns about your readings.
