janoslazarmunich I've figured out the answer within a week. The watch is capable of proper ecg measurement. Unfortunately a fabricated diagram arrives into the app. Test it measuring ecg with watch placed on your chest, just above the heart. During walking the only proper measurement is step counting. Even heart rate looks fabricated, filling the (often) failing results with earlier ones.

janoslazarmunich A varhato idopontra egy hettel kaptam meg. Europaba erkezese utan volt egy par hetes fekete lyuk (gondolom a vamon ult), a nyilvanvaloan itthoni tracking bejegyzesek utan nehany napra meghozta a posta. Keszulj, az ora ugyan pontos ekg adatokat mer (mutat), de a telefonra mar valami fabrikalt diagram erkezik ami mindig hibatlan. Ha a pulzusmeres nem sikerul, megnyugtato de a korabbi meresekre alapozott veletlenszeru ertekeket ad vissza. A ket csillagos, nem epp dicsero ertekelesemet nem raktak ki.
