-> The PineTime is a free and open source smartwatch capable of running custom-built open operating systems. Some of the notable features include a heart rate monitor, a week-long battery as well as a capacitive touch IPS display that is legible in direct sunlight. It is a fully community driven side-project, which means that it will ultimately be up to the developers and end-users to determine when they deem the PineTime ready to ship.

-> We envision the PineTime as a companion for not only your PinePhone but also for your favorite devices — any phone, tablet, or even PC.

-The **Pinetime** smartwatch is built around the NRF52832 MCU (512KB Flash, 64KB RAM), a 240*240 LCD display driven by the ST7789 controller, an accelerometer, a heart rate sensor, and a vibration motor.
