The city is frozen music, and Melotrace lets you hear its melody. Melotrace is your music map diary and urban music radar. Pin the songs you love to real places, explore nearby music signals, and now turn walks, commutes, and trips into replayable Music Journeys. Key Features: 1. Mapbox Music Map Explore your music memories on a smoother Mapbox-powered map. Every pin and every Journey belongs to a place, helping your listening history become a map you can revisit. 2. Music Pins (Music Footprints) Leave a song wherever you go. Whether it's a corner cafe or a midnight convenience store, pin the music that moves you in this moment to the map. Record your personal soundtrack and build your music memory map. 3. Music Journey Record a route while you move, connect Apple Music listening moments along the way, and generate a map replay with your route and song pins when the Journey ends. Journey currently supports Apple Music only. 4. Multi-mode Sonar Radar Activate Sonar to scan for music signals hidden in the urban forest. Standard Radar: Explore music fragments nearby. Power Radar: Extend your reach to capture faint signals from afar. Satellite Radar: Search the globe and listen to melodies from the other side of the world. 5. Flexible Privacy Public/Private: Boldly share your music taste, or keep memories just for yourself. Anonymous Publishing: Have hidden words inside a song? Post anonymously and let the music speak for you. 6. Soul Resonance When you discover someone else's music, tap "Resonate" to tell them: "I understand your mood." Check the "Resonance List" to see who has connected with your music, turning notes into a language of connection. 7. Energy Exploration Exploration comes at a cost. Plan your energy usage wisely to uncover more surprises within limited attempts. The energy system helps you enjoy the fun of exploration in your spare moments.
Treelet Diary

Stop staring at a blank page. Say how today went, or skip the typing: Treelet gathers your sleep, heart rate, workouts, calendar, the music you played, plus Watch voice notes and photo clues—and keeps a more concrete diary on your iPhone. Real daily drafts: come home to writing already halfway done—voice notes, calendar, photo themes, weather, and activity woven into the entry, with individual day photos embedded. Common Markdown renders cleanly in editor and preview. 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.
