Dozee is a one-of-its-kind health monitoring device from Indian health technology start-up Turtle Shell. Unlike most other health trackers and monitors, this petite device is not a wearable but a standalone unit that needs to be placed under the mattress to monitor and measure health vitals while you sleep. Priced at Rs 7,499, the Dozee is touted to monitor heartbeat, respiration and breathing rate data with 98.4 per cent accuracy. But is it really as good as claimed by its makers? Let’s find out: Dozee is basically a sensor sheet paired with a shell-shaped monitoring device that measures your health vitals while you sleep. The device connects with a smartphone through an app named after the device itself, available for Android and iOS platforms. The app syncs collects the data from the device and shows the measurements in readable format.
