Overview
Android 17 and Ellie are two vastly different products: one is a mobile operating system, and the other is a health companion app. This comparison examines their features, pricing, and ideal use cases to help you understand which is relevant to your needs.
Android 17 marks a significant shift in Google's mobile OS, transitioning from a traditional operating system to an "intelligence system." It introduces new developer APIs like AppFunctions and Android MCP, enforces adaptive-first app requirements, and brings features such as App Bubbles, Continue On, and enhanced privacy controls. It is aimed at app developers, device manufacturers, and Android users seeking the latest platform capabilities.
Ellie is a week-by-week companion app designed for people coming off or reducing GLP-1 medications such as Ozempic or Wegovy. It helps users maintain weight loss by tracking a trend line, setting a personal "line you will not cross," and providing a structured After Plan that anticipates the biological phases of appetite return. Key features include a Food Noise SOS panic button, a protein and strength floor, and a bring-to-your-prescriber export. It is free to download on iPhone, with a subscription unlocking the full plan. An Android version is planned.
