Perform calculations on fractions without converting them to floating point numbers. Floating point numbers that exceed the number of decimal digits are rounded or truncated, generating a relatively small inaccuracy. The solution is to use The Calculator with fractions capabilities.

Editors' Notes

All-in-one math tool for everyday calculations.


The calculator itself is fine but is plagued by ads

I've been using this app for years, no problem, the banner ad was always fine as it was out of the way. This was until the **video** ad was introduced. A VIDEO ad in a calculator app??!! The whole point of having this app is to quickly solve a little arithmetic with no pause, except you now have to wait for a video ad to load and wait for it to finish. Another thing that bugs me is that I can't listen to music while using this app, instead, the "Calculator App" takes over my sound?? And when I play that, it displays the sound as a link to a website? All I need is this app to not interrupt my music and not shove a video ad in my face every few minutes.

Developer Response

Thank you for contacting us with this issue. We are aware of this issue and hope to be able to have this fixed in a future update. Unfortunately I can’t make any promises about when this will be, as we are constantly working on a multitude of projects and bug fixes. We will do our best to have this problem fixed at some point though.

Our apologies for the inconvenience.

Apple calculator is better

One Star

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
