Welcome to Gantt Planet — where your life goals become the most beautiful scenery under the stars.

[KEY FEATURES]
Immersive 3D Planet Experience
Say goodbye to flat text lists! Each of your habits becomes a gem on a spiral orbit. With real day-night cycles and live weather effects (sun, rain, wind, snow), your planet reveals a different charm every time you visit. Watch mining carts shuttle along tracks, listen to soothing ambient sounds, and feel the path of your growth.
AI Tree Hole — Your Private Emotional Haven
Need someone to listen? A powerful on-device AI model (LLM) serves as your "Tree Hole" companion, always ready to hear your diary entries and innermost thoughts. It reads your emotional tags and responds with wisdom and warmth. Best of all, every conversation runs entirely on your device — never uploaded to the cloud — ensuring complete privacy.
Art Sticker Collection
Effort deserves rewards! Completing goals, writing diary entries, or chatting with Tree Hole can earn you beautiful art stickers. Over 2,500 illustrations across 5 art styles — watercolor, clay 3D, papercut, isometric, and more. Build your own digital journal and personal gallery.
Multi-Dimensional Timeline View
An original "equator" design cleanly separates daily routines from "New Me" personal growth goals. Three zoom levels — Week, Month, and Year (heat map) — let you see your life achievements from micro to macro.
Privacy First, Always Secure
We know your diary and habits are deeply personal. Gantt Planet uses a serverless architecture — all your data, habit records, and AI conversations are stored only on your device. PIN and Face ID lock support give you complete peace of mind.
