Very poor app. Limited functionality doesn't allow you to:
*add more than 2 charts
*doesn't have buttons 'Done' and 'Delete' so you don't have idea about what you are doing.
*automatically add chart without asking you.
*Doesn't allow you to delete the examples charts (Hillary Clinton, Donald Trump) which by the way are the only two
*Constant reports for Errors
*Doesn't allow the change of names wich appears by numbers !!!?!
1) There is a limit of 32 charts in the program, not 2
2) There is no "Done" button because this word is too general and does not state what is done. To finish charts editing tap CHACKRA button.
3) There is no "Delete" button because a "Remove chart" button exists
4) To rename a chart, edit its name in yellow font field under the "Rename current chart" label on "Charts" screen.

As to "automatically add chart without asking you. " and "Constant reports for Errors", it's unclear under what circumstances the
program adds charts without asking user and what error it reports.
