Go Figure!?

I have used this app for years. Simple, effective & reliable. Suddenly you add in that an Ad will start in 6 seconds, normally when you have looked away from the screen and the whole screen is an Ad when you glance back. We all have to earn a living and make a profit, but just be honest and say ‘This App is £5.49p/a’.
I have always awarded 5 Stars, but
even if it was an annoying banner Ad, but you ‘Force’ us to pay £5.49 because you can't use the app without paying. I have paid because I don't have the time to look elsewhere but, ‘Per YEAR is in my view greedy.
**I have updated the review to 3 Stars, as at least the developer took the time to reply.

What I Like About The Calculators!

I think the calculator is very useful. It comes in handy a lot when I need it. I don’t have to go onto the internet to use one when I have my own personal app. The calculator has helped me many times during hard and tough mathematics questions. When using the calculator everything that is one here is very clear and I can understand how to use it without any difficulty. My favourite thing about the calculator is that you can change fonts which I think is very amusing. This is what I like about the calculator
