28 Days Habit Tracker

Track daily habits in your toolbar, with optional habit-related AI via ZeroGPU when you use those features.

28 Days Habit Tracker is one focused product: daily habit tracking in your Chrome toolbar, with optional habit-related AI powered by the bundled ZeroGPU Browser SDK when those features are used (for example, summarization or classification tied to your habits). It is not a general-purpose AI assistant for arbitrary tasks unrelated to the habit experience. Habit tracking • Add habits with one line each (e.g., "Drink water", "Read 10 min", "Exercise") • Check off each habit for today with a single click • See your current streak in days for every habit • View how many habits you’ve completed today at a glance • Reset today’s checkmarks anytime with one button Optional AI (same product, habit-related) • The ZeroGPU SDK runs in a background offscreen context so ML/runtime code can load under Manifest V3 • When habit-related AI features are used, the extension may connect to ZeroGPU over HTTPS/WebSocket to run those features Privacy • Your habit list and completion history are stored in Chrome extension storage by default • If you use ZeroGPU-dependent features, habit-related content needed for those features may be sent to ZeroGPU’s services—see the privacy policy linked in the listing Why use it • Focused – One purpose: habits in the toolbar, with optional AI only in service of that experience • Fast – Open the popup, tick habits, close • Simple – No accounts required for basic habit tracking
