KnowMe: The warmest time to get to know yourself. Tangled worries lingering in your head, or earnest hopes for the future. If left only as thoughts, they quickly scatter and fade. Now, leave your thoughts as words in KnowMe. Passing thoughts will turn into radiant Mind Marbles, helping you face your true self. Created Mind Marbles can be stored or emptied into 3 special spaces depending on your state of mind: Emptying (Emotion Incinerator) "Burn negative emotions without a trace." Throw painful, jealous, depressing, or stressful emotions that suffocate you into the incinerator. (Not Saved) Marbles thrown here are completely incinerated and not saved in the app. Safely shake off the emotional garbage piled up in your heart and feel the true lightness of letting go. Filling (Future Mailbox) "The most reassuring parcel sent to your future self." Put your desired future, resolutions, and goals into a marble and drop it in the mailbox. (Saved) These marbles become letters and packages sent to your future self. Visualize the positive version of yourself that will arrive one day, and fill up on the driving force to live day by day. Gratitude & Pride (Tree of Growth) "Life's cheat code: Using positivity and gratitude as fertilizer." Hang your secret brags you couldn't tell others and the small moments of gratitude you found in daily life on the tree. (Saved) These marbles become special fertilizer that grows the Tree of Growth strong. Take them out anytime to fill up your self-esteem and see how wonderful you are and how full of thankful things your life is. Recommended for: Those who need a secret space (emotional trash can) to safely vent complex thoughts and stress. Those who want to visualize goals and resolutions for the future and gain motivation. Those who want to build a positive mindset and self-esteem through a gratitude journal. Those who want to look into their true heart and reflect through writing. A time to hold onto scattered thoughts and grow. Create your own marbles in KnowMe right now.
