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

Would be 5* without, but is 1* with the adverts


What a shame that this excellent app is now so spoiled by the ads, and the way they interact with the app. They are so intrusive that I will now only use the iPhone version of calculator with no ads. One is offered the box "CLOSE AD which opens the ad! I have found no way not to see the ad, and they can so easily be accidentally opened when using the calculator. And I am horrified to read in one of these reviews that accidentally opening an ad can result in auto-subscription. Certainly not a risk that I would wish to take. As for the monthly fee request if one wants a version not penalised by ads...........I could purchase a reasonable stand alone calculator for this sort of money. Sorry, but this is an app spoiled by greed.

Thank you for contacting us with your feedback. Unfortunately we have to use ads in our app in order to be able to offer the app for free, and have our company be financially stable. The ad pop-up that you described when tapping on the X is actually the menu to purchase the subscription, which not only removes ads but will also unlock all themes, improve currency conversions and give you premium customer support.

While some people somehow accidentally purchase this by accident, we in no way try to enforce this. We communicate the costs of the subscription and the benefits, and you have to confirm the purchase with your Apple ID, like you would any other purchase. This is all according to the rules & guidelines put in place by Apple.

I hope this at least explains things from our side to you, and want to assure you that your feedback will be taken into consideration. For more feedback you can always reach us at
