Yesterday, Pebble watch software was ~95% open source. Today, it’s 100% open source. You can download, compile and run all the software you need to use your Pebble. We just published the source code for the new Pebble mobile app!

Both use Nordic processors and the move to Zephyr OS should make it easier to go over. But the Pebble watches have a Nordic nRF52840 with 1MB flash and 256 MB RAM, but PineTime has the an nRF52832 with 512KB of flash and 64KB RAM. It will be a challenge squeezing everything down.

Pebble also has an ePaper display (B&W on Duo, 64 color on PT2) vs IPS capacitive touch display on PineTime. Then there's the matter of all the peripherals (IMU, mic, speaker, compass, haptics, buttons) that need to be supported. PineTime also has a heart-rate monitor that PebbleOS may not support (yet).

It's doable, but I suspect the lower flash/RAM will be a barrier. Someone might still try do to the port, given that the cheapest Pebble device is $149 and the PineTime is $27.
