Show IH - A Simple Note-taking Tool

Hi hackers,

This is my 1st post here and I would like to introduce a tool I made. Here is some highlights:

• Write with markdown.
• Type beautiful math formulae.
• Create mermaid diagrams.
• Sync notes into iCloud.
• Access your notes with any devices.
• Share stories with your friends.

You can try the web version from here:

Note:
The Web version only has basic features.
For better user experience, please try the native apps for Mac and iOS (both iPhone and iPad).
