Remember the Pebble smartwatch? At the time it was first launched on Kickstarter in April 2012, the device received the most funding of any product in Kickstarter history. The timepieces, which worked with both iOS and Android phones, started shipping in January 2013. The Pebble Watch started out successful with 300,000 units shipped during its first year, 1 million shipped by the end of 2014, and 2 million by December 7th, 2017.
Want to use your old Pebble Watch with a modern Android phone? You’ll need to install the Sideload Helper on your phone first
Alice Grey and Lavender Glaab, developers with the Rebble project, developed an Android app named Sideload Helper by Rebble. The app will open Pebble files on newer Android devices and transfer them to the Pebble app where they can be installed. The app helps you open .pbw (watchface/watchapp), .pbl (language), and .pbz files (firmware). If the user has Rebble Web Services set up, it will also translate Rebble appstore links including legacy links.
Take your Pebble out of the drawer, blow the dust off, and load the app on your Android phone
