The Mi Fit app, which supports Mi-branded smartwatches and smartbands, will now be called Zepp Life. The application interface has remained the same, but the name and logo have changed. Mi Fit is version 5.6.0 and it will be updated to Zepp Life version 6.0.0. The changes will be gradual until a full transition occurs. The next Mi Band 7 series is expected to already run Zepp OS.
The name Zepp is taken from Amazfit, now called Zepp. It is a division of the Huami brand.
