It’s a Calculator App So Here is my Review! C:

Dearest Calculator app Owner/owners, This is a Pretty Nice App to start off. 5 stars for sure. My Opinion on this app is, I like how it has like other things besides Multiplication, Subtraction, Addition, and Division. It is very nice. It helps me when I need to make quick calculations for math and sometimes when I’m gaming and I need to calculate the perimeter of whatever it is I’m doing. It is helpful and overall I really like it so far. I will update my review if I end up changing my Opinion on this App but for now I rate it 5/5 stars because I do not see any errors or problems with it so far. Thank you if you read my review Have a nice day and I think that’s all I have to say for now.

Requires a SUBSCRIPTION to remove ads

Who on earth in their right mind would pay a subscription for a calculator app when they could just use an online calculator like google? That is absolutely ridiculous. Cannot close the ads unless you pay real money. Starting at a dollar for a single month. Remember, it’s a subscription so after the month is up, it’s either pay us more money or more ads. Unbelievable.

Replying to your reply:
You say that since people use it for free, they will always see ads. Maybe they’re right, you’ll always see ads because there are so many that you can’t ever properly get to use the calculator.
My argument is that we get to use the calculator for free on our iPhones so why suddenly is it such a big deal to charge people or bombard them with ads. You already collect information from us anyways. I also don’t get why it would have to cost so much to use. There’s not that much programming compared to a 3D game. Other than tweaking it for updates here and there I don’t see much maintenance is required. If you still thirsty for money, perhaps if the ads were non intrusive like a banner that does not contain any moving parts or a video (terrible for battery and data) it would be less annoying and if the buying option was a flat out one time price instead of having to haggle every month. At this rate I’m more than happy to use my ti-84 instead of this ap.

Hello Bowl o Pears!
Thank you for your feedback on our advertisements. Unfortunately, in return for using the app for free, you will always see ads. We always want to offer the highest quality possible, and try our best to balance the ads so that they aren’t too intrusive, and will take your feedback into account for this. If you have any further feedback on the app please contact us at

Monthly fee? For a calculator?

I couldn’t figure out how to rate this app. I need a calculator for my iPad. It boggles my mind that Apple doesn’t have one automatically installed or available for the ipad like the iPhone. I found this one and thought I had solved my problem but the ads on this are more than obnoxious. They aren’t banners on the bottom or top- They are FULL PAGE pop ups you have to exit out of to move on. I like to use the calculator in the two-screen mode and this makes it impossible to exit out of the ad because the X is hidden. I have to open it in full screen mode then exit the add then go back to floating screen. It’s obnoxious and I end up just grabbing my phone to use that calculator 99% of the time.

Today I decided to just research if I could pay a small nominal lifetime fee to unlock a no ads version but they want you to pay monthly?! For a basic calculator? You’ve got to be kidding me. I found somewhere it said you can pay for the app or you can subscribe monthly but I can’t seem to find that option. It just keeps pushing the subscription. There is no way I’m paying monthly for this thing. I hate companies who try to price gouge.

I will use my iPhone calculator until Apple fixes their error and adds a free calculator to the iPad.
