Do you remember the Pebble Smartwatch? When the device was first introduced on Kickstarter in April 2012, it received the most funding of any product in Kickstarter history. The timepieces, which worked with both iOS and Android phones, shipped in January 2013. The Pebble Watch launched successfully with 300,000 units shipped in the first year, 1 million by the end of 2014 and 2 million by December 7, 2017.
Would you like to use your old Pebble Watch with a modern Android phone? You need to install the Sideload Helper on your phone first
Alice Gray and Lavender Glaab, developers of the Rebble project, developed an Android app called Sideload Helper by Rebble. The app opens Pebble files on newer Android devices and transfers 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 set up Rebble web services, they will also translate Rebble appstore links, including older links.
Take your Pebble out of the drawer, blow the dust off, and download the app to your Android phone
