GiveRoom is a private conversation coach that helps you listen generously and speak intentionally. Set your iPhone near the middle of a conversation. GiveRoom estimates how conversational space is being shared and can offer a gentle reminder when it may be time to pause, ask a question, or invite someone else in. Optional Conversation Canvas turns temporary live words into calm, rolling visual artwork. DESIGNED FOR REAL CONVERSATIONS • Choose a preset for friends, family, dates, or meetings. • Set the number of people and a suggested speaking target. • See when GiveRoom hears you, someone else, or is simply listening. • Receive a quiet prompt on iPhone or Apple Watch when a little more room may help. • Review private numerical patterns across recent conversations. • Share a beautiful reflection image that contains no transcript. CONVERSATION CANVAS Turn live speech into a full-screen, rolling visual experience. Choose a calm dark, warm, joyful, or high-contrast look and adjust text size, pace, and motion. English, Simplified Chinese, Traditional Chinese, and an optional Chinese + English mode are supported on compatible iPhones. PRIVATE BY DESIGN • Conversation audio is processed live and never saved by GiveRoom. • Live transcript text is erased when the conversation ends. • Speaker recognition and supported transcription run on the device. • Your voice profile is stored securely on your iPhone. • Optional history contains numerical reflections only—never audio or spoken words. • No account, advertising, analytics, tracking, subscription, or purchase is required. GiveRoom asks you to confirm that everyone present knows and agrees before every session. Speaking estimates and transcripts may be affected by distance, noise, overlapping voices, accents, and device placement. A percentage is a reflection, not a grade.
