Read documents created using LibreOffice or OpenOffice on the go, wherever you keep them, with the Document Reader! The file reader lets you open files like ODF (Open Document Format) documents created using LibreOffice or OpenOffice wherever you are. In the bus on your way to school wanting to look at your notes before the big exam? No problem! With the Document Reader you can open files wherever you like and read & search through your documents to go in a clean and simple way. There is a text editor in here as well, for the last typo before a document goes out. It is a young one and it does not reach every document yet, so the reader is what this app is for. The Pro version also adds new paragraphs, text formatting such as bold, colours and sizes, and more ways to mark PDFs: underline, strike out and draw. You can open files from ODF (ODT, ODS & many more) that you have created with Libre Office or OpenOffice also from within other apps.

Verdict
The clearest difference is price: One Scan at Free against OpenDocument Reader Pro's $3.99. One Scan also leads on rating (4.7 vs 4.2) and ratings volume (12K vs 292). OpenDocument Reader Pro's advantage is in-app purchases (none vs 10) and chart position (#65 vs unranked). On review sentiment, update cadence, ads and device support there is nothing between them.
Scored on Price · Rating · Positive reviews · Number of ratings · Update frequency · Ads · In-app purchases · Monetization · Best chart rank · Devices · Requires iOS
One Scan is free to download; OpenDocument Reader Pro costs $3.99 up front. One Scan sells 10 in-app purchases, starting at $3.99 per 7 days. OpenDocument Reader Pro asks for nothing beyond the download.
One Scan holds the better App Store score, 4.7 against 4.2.
