## What it is
InfiniTime is open-source firmware for the PineTime smartwatch, written in modern C++ on top of FreeRTOS for the nRF52 microcontroller. It provides watch faces, apps, and BLE connectivity with companion apps on Android, Linux, iOS, and the web.

## Use cases
- flash custom open-source firmware onto a PineTime smartwatch
- replace the stock PineTime firmware with a FOSS alternative
- develop custom watch faces and apps for PineTime
- connect a PineTime watch to Gadgetbridge or other companion apps
- learn embedded C++ development on FreeRTOS with BLE

## When to choose
- you own a PineTime smartwatch and want open-source, privacy-friendly firmware
- you want to hack or extend smartwatch firmware in C++ on FreeRTOS
- you need BLE sync with open companion apps like Gadgetbridge or Amazfish

## When to avoid
- you have a different smartwatch than the PineTime
- you need a turnkey consumer smartwatch experience without flashing firmware
- you want firmware for other nRF52 boards without porting work

## Facets
- artifact type: application
- maturity: active
- function: embedded
- domain: embedded-systems, hardware, cross-platform
- platform: embedded, iot, cpp
- tags: smartwatch, firmware, pinetime, freertos, nrf52, wearable, open-source-hardware, bluetooth-low-energy
