iA Writer for iOS provides comprehensive statistics on your document, including character, sentence or task counts, and estimated reading time.
These comprehensive statistics will help you monitor your writing progress, which is particularly valuable for writers paid per word, or those eager to take part in writing challenges like NaNoWriMo.
How To Display The Stats
You can enable stats via the Editor options: AA → Show Stats
The stats bubble remains at the top of the Editor allowing you to check your progress on the go. By tapping it, you can select the specific stats you wish to view.
Text Selection
The statistics adapt to the selected text.
If no text is selected, the stats for the entire document will be displayed. When text is selected, the stats specifically for that selection will be shown.
