Hello, We are Team NOTEGG. We have launched a new application [DEEP POOL] for those in need of comfort. There have been so many things that have happened to my couple. There were so many twists and turns from pregnancy to childbirth, and the joy of birth was also for a while, and the baby had to undergo a major surgery right away, so I had to spend each day in worry. In the meantime, it seems that the two of us cried and hurt a lot, crossing the rainbow bridge to the Munzi(my cat) of NOTEGG's mascot. As I lived with things I couldn't say to my family or friends, I became frustrated and depressed. At that time, I had the urge to spit out the feelings that had been piled up with anyone I didn't know. So, [DEEP POOL] was planned. I was feeling very frustrated and depressed as I was living with things I couldn't say to my family or friends. Every time I did, I felt the urge to spit out the feelings that had been piled up with anyone I didn't know. We started making [DEEP POOL] like that. [DEEP POOL] is a space where you can tell a story without revealing yourself. Feel free to tell the story. Throw the words you've kept in your heart under the deep puddle. It can be pretty words that support each other, or anything small. There is no empathy button like like or heart, Someone will listen to you and send a prayer of empathy and support. I hope this will be a healing for everyone who is frustrated, bored, or just wants to tell someone anything. It is a free application and has no ads. I will always be a NOTEGG working hard. [How to use] 1. You can enter text by touching the screen. 2. When I click the Done button, my writing sinks into the puddle. 3. If you touch the screen once more, you can see other articles in the pool. 4. All the stories of [DEEP POOL] will be deleted after a day. [Q&A] @: youarenotegg@gmail.com w: www.notegg.co.kr
