About Treelet Diary: AI Mood Journal
Stop staring at a blank page. Say how today went, or skip the typing: Treelet gathers your sleep, heart rate, workouts, calendar, and the music you played, and keeps the diary on your iPhone. It is for anyone who wants a mood journal but rarely feels like writing. Entries stay on this device, so you can see how your body and your mood move together. These insights are not a medical diagnosis or treatment. What you can do: • Voice to entry: speak a moment and get the text, along with a read of the atmosphere and energy. Results vary with the room and how you speak. • Mood and body on one timeline: mood, sleep, heart rate, workouts, and mindfulness, lined up so the day is easier to understand. • Daily Insight: what your sleep, calendar, and activity say together, instead of a recap of the weather and the numbers. • Know Yourself: gather who you are into tags. Dismiss a guess that misses, or keep the one that fits. • Weekly review: mood, sleep, and the words that kept showing up. • Treelet Pro: Treehole Echo after you write, app lock, blurred previews, iCloud sync, and PDF export. Monthly and yearly plans include a 7-day free trial you can cancel anytime. A one-time lifetime unlock is also available. You can write, use voice, and place the day’s health data into the same entry without a subscription. If you are struggling to cope, please seek professional help. Open it on the days you slept badly and want to see whether your mood dipped with it, when you already talked through the day and do not want to type it again, or when you want the entry to stay on this iPhone.
