A Good Sign

A Good Sign helps you understand the health signals already collected on your iPhone and securely use them with the AI assistant you choose. See workouts, sleep, activity, and supported heart-rate signals in a clear timeline. Explore personal bests and useful comparisons without digging through raw charts. On supported iPhones, ask descriptive wellness questions and get short answers using Apple Intelligence on the device. Your in-app questions, health context, and generated answers are not uploaded to A Good Sign or a third-party model provider. Connect a compatible assistant such as ChatGPT, Claude, Gemini, or another MCP client to ask about Apple Health categories you choose to sync. A Good Sign works with Apple Watch and other devices or apps that write supported data to Apple Health. Key features: • Recent health moments with clear summaries and comparisons • Personal bests, ranked performances, trends, and daily activity context • Private on-device questions on supported iPhones • Siri and Shortcuts access through App Intents • Read-only sync for supported activity, heart, body, workout, and sleep data • Secure Sign in with Apple • Encrypted server storage scoped to your account • OAuth-protected AI connections that you can review and revoke • Data export and in-app account deletion • No advertising, tracking, or sale of health data A monthly auto-renewable subscription unlocks on-device questions, backend sync, and AI access. Payment is charged to your Apple Account. You can restore purchases and manage or cancel the subscription from the app or your Apple Account settings. A Good Sign summarizes recorded wellness data. It does not diagnose, treat, cure, or prevent any condition, decide whether it is safe to exercise, or replace professional medical advice.
