Measuring

Type
Wrist
Irregular heartbeat detection
Yes
AFib detection or ECG
No
Method
Automatic oscillometric wrist measurement during deflation; the October 2021 manual describes inflation followed by gradual pressure reduction. First on-sale date unresolved
Accuracy
Static pressure accuracy ±3 mmHg and pulse ±5% of readout. October 2021 manual gives blood pressure 20–280 mmHg and pulse 40–200 bpm; current support instead lists systolic 60–255 and diastolic 40–200 mmHg. Cuff-pressure display 0–299 mmHg is separate
Clinical validation
Maker claims BIHS validation through the measuring technology of BP 3BZ1-3. Medaval reports no published exact-model peer-reviewed validation found; headline validation remains unresolved rather than treating the related-model claim as an exact W90 trial
Features
Ordinary irregular-heartbeat indication, audible measurement signals, two independently enabled daily reminder alarms, low-battery warning and automatic switch-off after approximately one minute. No dedicated AFib screening or MAM sequence established

Memory
Up to 99 dated readings for each of two user profiles; guest mode does not store readings. Time-button and memory-button sequence selects the user. Oldest reading overwritten when full; stored readings retained after cell replacement, while clock and alarms reset. History can be cleared for the selected user. Instructions establish individual recall, not an automatic average
Power
Two 1.5 V AAA alkaline cells, approximately 460 measurements with new batteries. NiMH cells supported with external charging. Polish product page's table says four AAA cells and DC 6 V, conflicting with its own two-cell package list and the exact manual; copied table is not adopted and no adapter interface is assigned

Design

Display details
LCD with ON/OFF, memory and time buttons; IP20 in October 2021 manual
Size
