### 1/5 — Uses non-compliant cookie ‘consent’ tool

*2026-05-07, version 7.1.1*

Use this if you fancy having to scroll through pages of cookie consents to opt out of data harvesting by all and sundry. Or do what I did and just delete the app when this nonsense pops up.

Developer response claims this approach is necessary for legal compliance.  That’s simply incorrect.  A one button opt out for all optional cookies would be fully in line with UK legal requirements for cookie management and is adopted by many websites and developers.  Making users crawl through multiple opt out buttons is unnecessary and obviously designed to make sure users don’t bother.

### 1/5 — Not secure!

*2025-08-10, version 6.3.0*

Uses remote server to process files (where?) and user must send password to open protected files = too risky for me.

### 2/5 — Not ready for prime time

*2024-11-23*

Bought the full version ($3… big deal). My experience is that it’s unreliable, had to access iCloud to see my Dropbox files rather than access Dropbox directly, and the paid version will not open password protected documents despite the developers’ claim to the contrary. Uninstalled it.

### 5/5 — Delivered the exact functionality I needed …

*2024-04-18*

This app allowed me to open an ODG file I created years ago. After opening the document, I was able to export the file as a PDF and import into Adobe Illustrator!

### 5/5 — Perfect for the task

*2023-06-21, version 6.2.4*

If you receive an email with a .ODT attachement, this app is EXACTLY what you need. 
Thank you to the developers. Brilliant work.

### 5/5 — The PRO version works good for me

*2023-03-02, version 6.2.4*

I'm able to read the OpenOffice documents and that exactly what I expected from this app.

### 1/5 — Work

*2022-09-29, version 6.2.2*

How do you even work with this app? I have ODT and I'm trying to open it. It does not pick up automatically the extension

### 4/5 — OOReader

*2022-08-09, version 6.2.2*

This app can also be used to display WordPerfect files in both iOS and Android versions. Nice!

### 3/5 — Resurfaced bug

*2021-04-05, version 6.1.4*

This bug appears to have resurfaced as of 6.1.2 or before (iOS 14.4). There is a faulty filename cache in which the filename is appended with a dash and incremental number despite prior copies of the file being deleted before re-downloading.

### 1/5 — Not great

*2020-03-18, version 6.0.0*

Wont open docs larger than 20-35 mb. I would know for sure but the error notice i receive is not written with good grammar so I’m unsure.
