InfiniTime is a PineTime firmware that is lightweight, tidy, supported by multiple companion apps and in active development. It's the current factory-default firmware on the PineTime.

The goal of this project is to design an open-source firmware for the Pinetime smartwatch:

  • Fast and optimized LCD driver
  • Bluetooth LE (BLE) communication
  • Rich user interface via display, touchscreen and pushbutton
  • Time synchronization via BLE
  • Notification via BLE
  • Multiple watchapps:
        - Clock (displays the date, time, battery level, BLE connection status)
        - Music control
        - System info (displays various info: BLE MAC, build date/time, uptime, version...)
        - Brightness (allows the user to configure the brightness of the display)
  • Supported by 2 companion apps (development is in progress):
        - Gadgetbridge (on Android)
        - Amazfish (on SailfishOS)
  • [Experimental] OTA (Over-the-air) update via BLE
  • [Experimental] Bootloader based on MCUBoot

Getting started

Build, flash and debug



Architecture and technical topics

Check the GitHub repository for even more details!

Ignore the wonky formatting, the forum's text editor is utterly unusable and super buggy.
InfiniTime just got a new release 0.8.3!

It's a hotfix release that helps avoid a hang that is often caused by a force reset done when the watch is in deep sleep.
InfiniTime just got a new pre-release 0.10.0 that more adventurous people can try out!

It has two new games and a bunch of small fixes.
InfiniTime 0.11.0 is out with Heart Rate and Navigation watchapps!

Beta testers can find downloads here:
InfiniTime 0.14.0 has been released with upgraded UI and a few bugfixes!
