Kaputt

Wenn man die App startet wird man in eine andere Umgebung weiter geleitet. Dort kann man zwar Vorlagen betrachten, diese aber nicht bearbeiten. Nicht überzeugt.

真的是良心软件,¥38该有的全有

Obsidian的问题是手机版本太慢,这个打开挺快的,渲染也很快,随时编辑,mermaid语法。试了好几个类似软件就这一个好用的。而且还支持macOS!!!iPad iPhone三端同步,不说了,再说像个吹子了。

Does what it says it does

I’ve purchased pro and have only been happy with it. I use it for all my mermaid diagrams, whether the other tools I use have mermaid diagrams built in or not.
This is an example of how a good, user focused, app should be written.
Not only is the app great, but the developer is extremely responsive and open to feedback.

업데이트 이후 느려졌어요

작성된 코드의 Redering 때문인지, 코드작성시 지연현상이 있습니다.

Last update (8.1) broke it for me

I can’t open complex diagrams anymore after the last update. When I do (after the app passes the loading phase), I can’t export to PNG. The button is grayed out. Trying to share via AirDrop also doesn’t work. 8.0 was working fine.
