They solve different problems. Bolt's Expo integration writes React Native code for you, and Bolt's documentation then tells you to download that code, open it in a code editor, and run
eas build --platform android to produce something installable. That means an Expo account, an EAS build pipeline, and a second codebase to maintain alongside your web app. Free App Maker takes the web app you already published and wraps it — no export, no second codebase, no native toolchain. If you want true native UI and native device APIs, the Expo path is the right one; if you want your existing Bolt app on a home screen today, this is faster.
