Gadgetbridge is an Android application for your smart watch and other devices
The Bangle.js 2 is an excellent device. As a former Pebble user, this is the first device that I consider an adequate replacement for my Pebble (which by now has a diminished battery life and corroded charging contacts).
Here is my impression of the Bangle.js 2:
- Battery: Lasts about 3 weeks on a charge, constantly connected to my phone, when the watch is used to display notifications and alarms. This is a major advantage over Apple Watches and Android/Wear OS watches.
- Display and buttons: The 1.3" 8-color transflective display is comparable to the Pebble Time series' 64-color transflective display. The display is always on, and the backlight activation is highly configurable. The Bangle.js 2 has a touchscreen and 1 button, while Pebble watches have no touchscreen and 3 buttons.
- Software: Runs on the completely free and open source Espruino JavaScript interpreter,[1] which was my main motivation for purchasing this device. There are currently 336 apps in the web-based Bangle.js app loader (app store), including utilites and clocks (watch faces), all of which are FOSS. The bootloader and firmware can be updated directly from the app loader. On Android, there is a distribution of Gadgetbridge (built from the same code base as Gadgetbridge) with internet access enabled that integrates the Bangle.js app loader into Gadgetbridge, which makes it very easy to use the watch.[2]
- Build: Built on the same device body as the SMA Q3.[3] The casing is plastic, and the watch is compatible with standard 20 mm watch straps. The IP67 water/dust resistance makes the watch usable for sports.
Overall, I highly recommend the Pebble.js 2 watch, which is the best FOSS-focused watch I have found to date.

Can the PineTime Watch stream music without a phone? (Onboard music storage)
There are subsets of JS for embedded device e.g. Espruino https://github.com/espruino/Espruino for BangleJS https://shop.espruino.com/banglejs also with 4MB or JerryScript https://jerryscript.net

[AskJS] Do you use JavaScript on Microcontrollers? Which engine / interpreter?

Microsoft DeviceScript – TypeScript for Tiny IoT Devices
Agree 100%
That was my point - the ESP32 is so versatile and cheap, it's my go-to these days for pretty much everything.
Being about to have an easy and reasonably powerful js runtime for that sounds great.
Apparently node-red also has something for esp32?
And I haven't tried it, but low.js looks cool too [1]

I fell in love with low-JS
Oh, I thought this was going to talk about low.js (https://github.com/neonious/lowjs), the "node.js" runtime for micro-controllers and tiny embedded systems.
