### 5/5 — Great app!

*2024-04-24*

This app is great! None of the mobile word processing apps allow you to compare two documents. This app allows you to easily enter both of your documents and edit whichever one you want to (old or new). 

The only thing it doesn't have is an automatic way to click on a word and swap between the original and clean words. If you want to make a change, you have to manually type it in.  Though what it does do, it does well. It has a great instruction manual, and it’s clumsy-finger friendly too.

You need a subscription to edit more than 100 words, but otherwise all features are free. The subscription at the time of this writing is about $6 per year.

**Developer response:** Thanks. The feature to swap between original and modified words has now been added, and can been accessed from the context menu on the blackline text.

### 5/5 — Great blacklining solution.

*2020-10-06, version 1.5.4*

The ability to create simple blacklines of text that can be exported in clean and blackline form with ease is a game changer for lawyers or anyone who edits written work. I love this program!

### 5/5 — Best black lining program ever

*2019-07-09, version 1.1*

Bliner is great.  I use it on a regular basis to compare text and send changed text over email.  It’s super helpful to be able to do this on my phone without having to go to a computer.
