About this app

Are you tired of real-time chatting?

Jinshim is a place where you connect with new friends through letters you've waited 6 hours for.

More than appearances, the warmth felt in a single letter written with sincerity.

Meet like-minded friends amidst the aesthetics of slowness.

● Key Features

1. Unadorned Daily Life, 'Today's Diary'

Record the thoughts, scenery, and emotions that brushed past your mind today in a diary. Share your daily life and discover like-minded friends by reading the sincere records of others' lives.

2. The Exciting Wait, '6-Hour Letter'

A letter sent to the recipient takes 6 hours to arrive. Instead of instant conversation, convey your sincerity by carefully writing each word with the other person in mind. The time spent waiting makes the conversation between the two of you even more precious.

3. Depth Over Speed, 'Slow Communication'

Escape the pressure of real-time chatting. We aim for slow and warm communication, matching each other's rhythm, by reading and writing replies to letters that arrive during the quiet hours of your commute home or before falling asleep.

4. Safe and Refined Communication

We place great importance on sincere records and polite communication. Rather than indiscriminate conversation, we build trustworthy relationships through the medium of writing and letters.

● Recommended for:

Those who desire slow conversations with like-minded people rather than casual encounters

Those who wish to record their daily lives and share them warmly with someone

Those who appreciate the excitement of anticipation and the lyrical sentiment of letters

Now, convey your 'sincerity.'

In the flow of time, your ordinary diary becomes the most special letter to someone.
Share your diary and exchange letters with friends.
