Ratings and Reviews
i never thought I would enjoy using a calculator, but I do enjoy using this one!!!
It’s background changing ability is awesome, and I find my self switching to cool new backgrounds while I’m using it. It’s also really easy to use, and I like how you can change the button shapes!!!
Also if you need something more, you can just buy one of the add-ons and you can count money, you can do fractions, you can do scientific.... I love this app and I totally recommend it to people in need of a calculator!!! I don’t understand why there are so many bad reviews about this app. Also, the only adds in this are really small and smushed into the bottom of the screen,
Not blocking anything or really doing anything bad. I play on my phone a decent amount, and adds can get extremely annoying wen they pop up and cover the hole screen and start playing a five minute add. this is definitely an improvement ilI LOVE THIS CALCULATOR.
Please just make a one time in-app purchase fee!
I absolutely love this app, since use it for school and it is just very simple to use while also being able to use more complex equations! My only problem is the fact that I have to pay a monthly fee just to use other calculator features that are on normal calculators is just ridiculous! I understand that you guys want to make money, but do you really, like really need to make people pay a monthly fee just to be able to calculate fractions! I would be absolutely fine if it was a one time fee, but why a monthly fee!? This is one of the top most downloaded calculator apps on the App Store if not the best one, not to mention the little adds at the bottom (not distracting at all) that you make money off of adds which shows you already make quite a bit of money off of more than half a million user, yet you have to go even farther to make me pay for a monthly fee for features in every ordinary high school level calculator! I would rather have to pay 5-7 dollars once for all of the other features instead of being fed off of for multiple years to come of using this app. I would rate this app 5 stars right off the bat if it got rid of the monthly charge and maybe even replaced it with a one time fee. Please address this concern, and thank you so much for your time.
Ads are unbearable and they changed ad free subscription
I’ve been using this app for YEAAAARS.. it’s been so long I honestly can’t even remember how long it’s actually been. I use the calculator a fair amount of times but it’s not a super frequent occurrence and originally I wanted this calculator because the Apple calculator wouldn’t let me delete a typo without deleting the entire calculation and this also tracks calculation history. Anyway, I paid for the $2.99 ad free upgrade a few years ago and everything has been fine up until a few months ago I randomly had a $2.99 credit on my Apple account.
At first I had no idea where it came from UNTIL I went to use the calculator and an annoying ad covered the entire screen. Apparently they changed things and instead of a one time $2.99 charge they want $1.49/mo to use the calculator ad free. The little ads at the bottom aren’t bad but the thing that makes it unbearable and the reason why I’m deleting the app after at the very least 5 years is the ads that popup while I’m in the middle if typing which ultimately lead to me clicking on the ad and opening up safari or app store. I don’t like the fact I’m forced to open unwanted ads to god knows what. I don’t want that on my phone. Such a shame. I might have failed math in high school but this calculator is not that important to me to have to deal click on ads because they pop up while I’m typing.
Developer Response ,
Thank you for contacting us with this issue. If you have paid for ad removal in the past through buying the full version, then the Restore Purchases doesn’t work for you. The reason for that is that the full version is a separate version of the app that you need to download for the App Store. The Restore Purchase is for our new model with subscriptions, but that doesn’t mean your old purchase didn’t remain intact. If this is the case then you can simply download this again from the App Store by searching for ‘Calculator Impala Studios’, or access it through this link: https://apps.apple.com/us/app/the-calculator/id396082453. You won’t be charged for this as the purchase is linked to your Apple ID. We will also make sure to still be updating and testing the full version of the app.
I hope this solves your problem, and would like to apologise for the inconvenience. If you have any other questions or issues in the future, please do not hesitate to contact us at email@example.com.
