New to InfiniTime?
Companion apps
- Gadgetbridge (Android)
- AmazFish (SailfishOS)
- Siglo (Linux)
- InfiniLink [Experimental] [Unmaintained, looking for developers/maintainers] (iOS)
- ITD (Linux)
Development
- InfiniTime Vision
- Rough structure of the code
- How to implement an application
- Generate the fonts and symbols
- Creating a stopwatch in Pinetime(article)
- Tips on designing an app UI
InfiniSim Simulator
Use the InfiniSim Simulator to experience the InfiniTime user interface directly on your PC, to shorten the time until you get your hands on a real PineTime smartwatch.
Or use it to develop new Watchfaces, new Screens, or quickly iterate on the user interface.

I’m not working alone on this project. First, many people create PR for this projects. Then, there is the whole #pinetime community : a lot of people all around the world who are hacking, searching, experimenting and programming the Pinetime. We exchange our ideas, experiments and code in the chat rooms and forums.
Here are some people I would like to highlight:
- Atc1441 : He works on an Arduino based firmware for the Pinetime and many other smartwatches based on similar hardware. He was of great help when I was implementing support for the BMA421 motion sensor and I²C driver.
- Koen : He’s working on a firmware based on RiotOS. He integrated similar libs as me : NimBLE, LittleVGL,… His help was invaluable too!
- Lup Yuen Lee : He is everywhere: he works on a Rust firmware, builds a MCUBoot based bootloader for the Pinetime, designs a Flutter based companion app for smartphones and writes a lot of articles about the Pinetime!
