A curated list of awesome projects, tools, documentation and resources for the PineTime - Pine64's open-source, hackable smartwatch built around the Nordic nRF52832 (ARM Cortex-M4F).
The PineTime is a fully open development platform: open firmware, open schematics, and an active community building operating systems, emulators and companion apps. This list collects the most useful starting points for hacking on it.

- InfiniEmu - Full hardware emulator of the nRF52832 (Cortex-M4 + peripherals: accelerometer, touch, heart-rate sensor, SPI display) that boots real InfiniTime firmware. Written in C with a Go/TypeScript/Vue web front-end.
GPL-3.0 - InfiniSim - Official desktop simulator that builds and runs the real InfiniTime UI on your computer (no hardware needed), ideal for developing watch faces and screens.
GPL-3.0 - pinetime-emu - A Cortex-M4F emulator that boots PineTime firmware without hardware, simulating nRF52832 peripherals (UART, SPI, I²C, BLE radio) with SDL2 display rendering and touch input. Written in C++.
Phone- and desktop-side apps that pair with the watch over Bluetooth LE to push notifications, control media, sync activity data and flash firmware. Feature support: ✅ yes · ➖ partial / version-dependent / unconfirmed · ❌ no.

¹ Gadgetbridge doesn't fetch weather itself; it relays it from a separate provider app (e.g. Breezy Weather).
² Activity = syncs/logs step and heart-rate history off the watch. Apps that only read live values for on-screen display (WatchMate, itd) or list it as planned (wasp-companion) are marked ➖.
³ none = no license file published, so the code is effectively all-rights-reserved.
⁴ PinePartner is pre-alpha (v0.0.6) and built around a JavaScript plugin system - its notifications and media control are themselves built-in plugins.
- pinetime-mcuboot-bootloader - The open-source bootloader the PineTime ships with (MyNewt + MCUBoot), enabling safe over-the-air firmware updates and rollback.
Apache-2.0 - nRFConnect - Nordic's closed-source BLE tool, usable as a bare DFU flasher (Android · iOS; recent iOS builds reportedly no longer flash PineTime).
proprietary - pinetime-flasher - Linux Flatpak/GTK flasher for InfiniTime, RIOT or custom binaries from a URL or file.
Apache-2.0 - pinetime-updater - Flash firmware over a wired SWD connection with OpenOCD - the reliable recovery path when BLE OTA isn't possible.
Apache-2.0 - PinetimeFlasher - Windows firmware-flashing helper for InfiniTime. (license unverified)
- WebBLEWatch - Web Bluetooth proof-of-concept that sets the InfiniTime clock from a browser (time-set only, not a flasher). (no license file)
- GTKWatchFace - A themeable GTK3 watchface generator (Python/C/C++, Linux) that renders designs and converts them into C++ code and font files to compile into InfiniTime.
