Ole Zorn’s iOS text editor Editorial has just been updated to version 1.2. This is a major update—basically “this year’s model”—and the people who know from iOS text editors hail it as the best. It’s got great editing features and great automation features, and works on iPad and iPhone.
As Federico Viticci writes at MacStories:
If I had to pick one iOS app I couldn’t live without, that would be Editorial.
