Name can be changed to ‘calculator’ instead of ‘calculator#’

Really nice app but after about five times used, it opens without pressing%. Also the app shows ‘security products’ written as soon as we open the app by which anyone can assume that it is not only a calculator. You can show that credits page after we enter the password. Overall it is avery good app and functions perfectly.

App not working

When I open the app, blank(black)screen appears and it closes after around 10 seconds without any error response.
The problem began when my storage got full and the app got offloaded itself because of the storage issue. When I reinstalled the app, it was showing above mentioned problem again and again. Kindly assist me asap.
