Occurrence Counter is an app, which takes two inputs
i) a selected text content
ii) a sequence/word/letter whose occurrence count in the selected text has to be found.
there is an option to categorize the counting, whether the counting of the sequence should be case sensitive (or) case insensitive.
By default it is case insensitive.
On pressing the Button 'Count' the count of the sequence in the selected data is displayed.
If nothing is selected or entered a suitable message is displayed , which prompts to select some data.
