This guide is now in maintenance mode. Rebble made their own official guide based on this, so please follow the updated guide on their website at help.rebble.io/sideload-ios-app. If you have any suggestions, ping me (@robonxt) or one of the helpful people in the official Rebble Discord Server and hopefully there will be a guide update soon!
Thank you for all the support, and long live Pebble and Rebble!
Fun Fact: I've never daily driven Pebble on iOS before, only to test out sideloading and to ensure the guide works with the iOS devices I have 🤣
