### 1/5 — Can’t get it to work at all

*2026-02-25, version 1.3.8*

See above

### 4/5 — amazing !!!

*2026-02-05, version 1.3.8*

typing equations is so much easier now

### 5/5 — suggestion

*2026-01-09, version 1.3.8*

It is good! However, can developer add a shortcut or button for me to quick type $$ or mk since obsidian need this to start write the latex expression.

### 5/5 — Excellent

*2025-11-21, version 1.3.8*

Nadlren, I think there are some incorrect displays due to my writing. Generally, however, it does the job perfectly. It saves a lot of time and effort, especially with long formulas.

### 1/5 — 苹果手机版使用体验

*2025-11-04*

目前无法转换数学公式

### 5/5 — super einfach, sehr gut!

*2025-11-02, version 1.3.8*

eine der sinnvollsten und zeitsparensten Investitionen der letzten Monate!

### 5/5 — Highly Reccomend

*2025-09-18, version 1.3.8*

Super helpful tool if you’re like me and would rather write out math instead of typing tedious latex commands. Accuracy is usually spot on if you write with decent handwriting. The website is super helpful too, I like writing on my iPad and having it instantly send to my computer where I can either copy the latex code or just copy the output as an image.

### 4/5 — App funktioniert nicht mehr (Juli 2025)

*2025-06-05, version 1.3.8*

Der Server ist seit Tagen offline, auch der Entwickler ist daher nicht mehr zu erreichen. Damit ist App leider komplett wertlos geworden (und meine Investition in den Kaufpreis). Sehr schade…
Nachtrag: Der Entwickler hat sich gemeldet mit der Nachricht, dass der Server wieder online ist. Gut so!

### 5/5 — اصبح سيء

*2025-06-01, version 1.3.8*

لايمكن استخدامه على الكمبيوتر كما كان سابقا ولا ينسخ الصور
