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.

Very good app but....

This is a very good calculator app, but it could have some speed improvements on the Apple Watch. I have an Apple Watch series 3 and it is not very responsive when you tap on a number.

All Adds Up

Really impressed with this app.
Use it daily.
Like that I can refer to my previous sums.
Excellent clear display.
Just the ingredients you need to make a good all adds up!
