KnowItOwl! puts a voice-first question-and-answer assistant on your Apple Watch and iPhone. Raise your wrist, ask a question, and hear a concise answer spoken aloud. On iPhone, you can also type questions, review your shared conversation history, replay saved audio, choose a voice, and manage credits. KEY FEATURES - Apple Watch voice questions with spoken answers - Voice or text questions on iPhone - Concise answers grounded with Google Search when available - Multilingual transcription and responses - Four selectable voices: two multilingual and two English - Shared conversation history across iPhone and Apple Watch - Watch face complications for quick launch - Digital Crown volume control during Watch playback - Encrypted message text and audio storage - No advertising or third-party behavioral tracking HOW CREDITS WORK Each voice or text question uses one credit. New accounts receive a 20-credit welcome gift, and 5 free credits are added each month. Credits do not expire. Additional consumable credit packs are available from iPhone and Apple Watch; App Store Connect supplies the localized prices. PRIVACY Before the first question, KnowItOwl! explains what data is processed and asks for permission. Voice recordings or typed questions and up to three recent messages are sent through Sandy Brook DevWorks' authenticated backend to Google Cloud Speech-to-Text, Vertex AI Gemini, Google Search grounding, and Cloud Text-to-Speech as needed to produce an answer. Permission can be withdrawn at any time from Settings, which stops new AI questions on both iPhone and Apple Watch until it is allowed again. Message content and stored audio are encrypted on the device before they are saved to Firebase. See the privacy policy for retention and service-provider details.
