### 1/5 — Buggy and falls short

*2026-05-10, version 6.3.2*

The system fails to respond to touch commands and has to be closed frequently. It also does not link to my OneDrive as advertised. It effectively is useless for any meaningful work.

### 5/5 — Great

*2025-11-18, version 6.3.2*

Useful app. Please, add the Spanish dictionary, if possible. Thanks!!

### 3/5 — Where are you? Are you listening?

*2025-01-11, version 6.3.2*

I have been using this LaTeX tool for several years and it has been consistently a fine compiler, but within the last year or so, customer support, which used to be prompt and helpful has become nonexistent. The program continues to have horrible file management and the sync to Dropbox feature is inconsistent.

### 1/5 — Highly disappoing

*2024-09-16*

Buy it not when it is free.

### 1/5 — No support

*2024-07-24, version 6.3.2*

The package developer has completely ceased their internet presence in all ways. This package will probably never be updated. Buy something else.

### 2/5 — Poor support

*2024-05-29, version 6.3.2*

Could be good but has glitches and issues and the support email doesn’t seem to respond.

### 2/5 — GOOD

*2024-05-05, version 6.3.2*

MUY BUENO, PERO LA ÚLTIMA ACTUALIZACIÓN LIMITÓ EL USO DE CMD T, CMD S Y OTRAS... POR FAVOR MEJORAR ELLO

### 2/5 — Findet Dateien nicht

*2024-03-27*

PNG-Dateien im selben Verzeichnis wie die tex-Datei werden nicht gefunden, was auf dem Mac mit texShop kein Problem ist. Habe die Tex-Version mit dem pro-Abo. 
Momentan: Schade ums Geld….

### 2/5 — lack of support

*2023-10-20, version 6.3.2*

There have been no updates for a couple of years and it seems impossible to access documentation on website.

What used to be an excellent app no longer is.  You used to be able click PDF file to go to relevant place in tex file but this no longer works after a recent IOS update.

So sorry that what used to be an excellent app is now so outdated.

### 2/5 — Very disappointed

*2023-09-24, version 6.3.2*

This is a very primitive app. You can’t even navigate to folders elsewhere on the iPad. Go with a free program first and see if it works for you.
