Please Note: Bangle.js is an affordable Smartwatch with entirely open software, designed to be trivial to write your own apps for. While the watch is solid and well built, it can not compete with an Apple Watch costing 5x as much, and is not intended to. If you have any reservations we'd advise you to read some impartial reviews first.
