Bangle.js - Hackable Javascript Smart Watch

  • Description-


    Bangle.js is an open, hackable smartwatch that anyone can code for - and best of all it's open source so you don't have to worry about a server getting shut down and losing functionality - it's fully self-sufficient! You can easily install new apps from the web or develop your own using JavaScript or a graphical programming language (Blockly). All you need is a Web Browser (Chrome, Edge, or Opera), and you can upload apps or write code to run on your watch wirelessly! Bangle.js is waterproof and AI-enabled and comes with Bluetooth Low Energy, GPS, a heart rate monitor, an accelerometer, and more.
