User reviews

glitchy

I like the app BUT occasionally it doesn’t compute the % of time within zones. The graph works but not the lower % table.

La aplicación no es como la imagen.

La aplicación no es como las imágenes, solo rastrea frecuencia cardiaca, pasos y frecuencia en reposo.
Se está rastreando con
HW 9 coospo.
También no te guardan los pasos que llevas en el día, los pierdes si lo apagas y lo vuelves a conectar ò si pierdes conexión bluetooth.
Esperemos un actualización ò que dispositivo es para que rastreen todo, ( FR, FRV, TEMP. Oxígeno en sangre,etc.)
Le doy 3 estrellas, por casi, ir exactamente medición con la del pecho, ( aunque creo que el brazalete y no la app)
