Kokone is a journal you keep by talking. Tap the mic and say what happened today. Kokone turns your words into text, shows a breakdown of the emotions in what you said, and gives you a short coaching message along with one question to think about next. You don't need to write well, or write at all. One sentence is enough. WHAT YOU CAN DO • Voice journal: speak, and your words are turned into text • Photo journal: add a photo and say a few words about it • Handwriting: take a picture of a handwritten note and Kokone reads it • Emotion breakdown: see which emotions showed up in each entry • A question for next time: based on what you actually talked about • Mood over time: a chart for the past week, 30 days, or 90 days • Daily question: a notification at the time you choose, with a question that fits the time of day. No streaks, no pressure APPLE HEALTH If you turn it on in Settings, Kokone saves the mood you choose when recording to State of Mind in the Health app. The text of your entries and your photos are never written to Health, and Kokone does not read your Health data. Requires iOS 18 or later. PRIVACY • Your entries are stored only on your device. No account is required • For the emotion analysis, the text and any attached photo are sent to an AI service (Claude API by Anthropic) after you give consent. They are not used to train AI models • No ads, no tracking SUBSCRIPTION Kokone Premium is a monthly auto-renewing subscription with a 7-day free trial. Payment is charged to your Apple ID. It renews automatically unless canceled at least 24 hours before the end of the current period. You can manage or cancel it in your Apple ID settings. Terms of Use (EULA): https://www.apple.com/legal/internet-services/itunes/dev/stdeula/ Privacy Policy: https://strobofactory.github.io/kokone/#english Kokone is a tool for self-reflection. It is not a medical service and does not diagnose or treat any condition.
