Description by 北京小树科技有限公司 Written by the developer, not by AppBrain. Click to read.
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.

Apple Watch Voice Stream: speak on your wrist—Smart Note can auto-start or nudge—then sync to iPhone for transcription and a one-tap diary draft. Optionally download on-device Whisper for clearer Watch ASR; without it, Apple Speech still works. Audio stays on-device by default.

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:
• Watch / 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 living tags for who you are. Keep what fits; dismiss what misses.
• Weekly review: mood patterns, sleep, and words that kept showing up.
• Treelet Pro: Treehole Echo after you write, app lock, list blur, iCloud sync, and PDF export. Monthly and yearly plans include a 7-day free trial you can cancel anytime, or unlock once for life.

You can write, use voice, and keep the day’s health signals together without subscribing. If you’re struggling to cope, please seek professional help.

You’ll open it when you’re commuting and want to capture a thought without unlocking your phone; when sleep is short and mood dips with it; when you already said a lot and don’t want to type it again; when you want the words to stay on your device first.

Permissions:
Motion & Fitness, Microphone & Speech Recognition, Calendar, Media & Apple Music, Location & Weather, and Apple Watch recording / notifications are requested only when you use those features. You can turn them off anytime in Settings.
