One Star

Apple calculator is better

I'm with everyone else who gave a one star review. The app was fine, it's a calculator and that seems simple enough. I wasn't sure you could go to far wrong with a calculator app. The ad banner was a bit ugly but bearable. Now these ads are popping up with video ads I have to wait to skip. I only use this app when I can't be bothered to get my phone out my pocket and the iPad is to hand because (despite the slightly obvious random 5 star rave reviews) the apple calculator is better.
I'd pay a couple of dollars for a calculator app I think that fair. But I'm not paying a subscription.
Think these developers have over-estimated how much value a calculator app can bring to some ones life.

Developer Response

Thank you for contacting us with your feedback on our advertisements. We are hearing your complaint and that of others, and have reduced the ads and removed the subscription. In the new update you can remove the ads for a one time purchase, and should have less ads then before.

We do have to use ads in the app to be able to offer it for free, as we still need to make a living as a company. We are constantly trying to find the right balance in this, and feel that this update is a step in the right direction.

If you have any further feedback on the app, or suggestions to improve the usability, please feel free to contact us at

Very useful device. This update which have only now implemented, will be put to the test in the next month, if anything like the first version, will be interesting. I found the first version had no bugs that I could find. Good work tool !
It's a great tool. Of the best I have found and very little has gone out of kilter during the last three years and sinceI first started using it. Thank you
