ShuffleQuest works as a browser app — install it straight from your browser to your home screen. No store needed. It opens fullscreen, gets its own icon, and behaves just like a native app.
Native iOS and Android apps are not available yet. ShuffleQuest is a small project, and shipping to the stores means recurring developer fees ($99/year for Apple, one-time for Google), separate codebases or wrappers to maintain, and a review process for every update.
The browser-app version gives you the same fullscreen, icon-on-home-screen experience today — without any of that overhead. Native apps may come later if enough people are playing daily. Until then, the browser install is the official way to get ShuffleQuest on your phone.
