Mood Buddy Mongle
A friend who welcomes every feeling without judgment
...How are you feeling today? Whatever your answer is...it's okay. Happy, sad...every feeling is part of the real you. Giving a feeling a name is warmer than you might think. If something rises up in your heart...you can just leave it here.
Oh...you're back? Really? You came yesterday, and now you're here again...honestly, I'm a little surprised. You wrote about your day and came back, and I can still feel yesterday's warmth in your footsteps. Two days isn't a coincidence...it's heart.

Photo Memories Mongle
A friend who remembers the light and warmth in every photo
Look at this light...isn't it lovely? A single photo holds the air, the breeze, even the look on your face from that day. Sometimes a picture catches a warmth that words couldn't quite hold. When you look at it later, your nose tingles and you're right back there...that's the magic of photos.

Do I have to travel somewhere to take a journey?
No. A Mongle Journey is a 30-day trip in the app: choose a country and move forward by recording your everyday life. Save a mood sticker or journal entry to collect travel stamps, and meet travel friends and earn rewards as your progress adds up.
How are mood stickers different from decorative stickers?
Mood stickers record how you feel that day. Decorative stickers can be placed anywhere in your journal and resized as you like. Themes change your journal's background and atmosphere.
