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.

Algorithms by Jeff Erickson (Free algorithms textbook)
I like the awesome-algorithms link, but some of the code linked is definitely not perfect. A few questionable things from one of the header files [0] in https://github.com/TheAlgorithms/C:
- Defines a macro with no parentheses
- Uses unsigned for length and capacity (should be size_t)
- Uses () instead of (void) for an empty parameter list
- Useless use of "extern" for function declarations
- I think that leading double underscores and structures ending with _t are reserved identifiers, but I don't really have a good source for this
