Calculator with Notes

This appears to be an excellent calculator but it’s infested with looping adverts making it nigh on impossible to use. Apple need to have a word within developer because this is clearly unacceptable.

My saved calculation are not opening . It exits the app when I try to open . Please fix the bug

This is really nice app. But crashing when switching between text and numbers. Not always but can't predict when it crashes. It would also be nice to add comma separator add I am used to it while typing to recognize the number positions. Unable to edit the name/title of saved notes. Remembering last time entered text is annoying(if it's a feature otherwise consider this as bug). However I gave 5star as I am sure you would consider my requests and fix these issues. I was planning to buy but these are something I am looking forward before buying.
