Lumein.

Every day leaves a feeling behind. Lumein turns that feeling into a small glowing node and links it to the day before, so over weeks and months your moods grow into a living piece of art that is only yours. Each evening you pick how the day felt from eight glowing moods, choose one of eight shapes, set the brightness and pattern of the light, and add a short note or tag if you like. Every node also gets its own gentle vibration rhythm, so you can tap it later and feel that day again. Your chain can be viewed as a line, a spiral, a constellation or a wave. Pinch, drag and twist to explore it, tap any node to revisit its note, filter by mood, tag or date, and watch a replay of your chain growing from the very first day. Small rituals keep it meaningful. Seal a note to your future self that opens in 30 days, 90 days or a year. See what you felt one month and one year ago. Light every day of a month to turn it into a collectible gem. A seven day streak earns an ember that covers a missed day. Insights show your mood balance, streaks, a calendar of lit days, how one mood tends to lead to the next, and which tags carry your brightest days. Choose from three color themes, collect badges, and save your chain or a single day as an image or video to keep or share.
