Apart from the looks, the ColorFit Ultra is a capable watch, with heart-rate, stress monitoring, sleep monitoring, and SpO2 sensor (to measure blood-oxygen levels). It can also track the menstrual cycle.
While the watch collects everyday data, it's the NoiseFit app that gives you further insights. You can check all your notifications after pairing them with a phone but can't reply to them. There is no option to receive a call, but you can reject it or reply with a message using the watch.
Overall, the watch can track 60 sports modes, including weight training, cycling, yoga, cricket, badminton, zumba, and more.
