Great app!
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.

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.
