This Calculator Ap is not is that good!

First of all, I have to say I haven’t been this excited about a calculator since I unboxed my TI-30XIIS. I am so grateful for the persistent and not at all intrusive or annoying reminders to rate this AP. Finally I am taking advantage of writing this review, which will make little or no sense at all. I’m giving the AP 5 STARS because it does calculations 1000% of the time I ask it to. And 100% of the time it gets it right each time, I mean every time. I’d love to share my experiences with this calculator, I mean serious things. I mean one time I used it to calculate the mass of the moon based on gravitational force of the earth and the given distance of the moon from the earth. It turned out to be like the weight of around 300billion elephants or something like that. Which is amazing... that I could take 300 billion elephants and put them together at about 300,000 miles away and they would compress into one another and orbit earth and probably the water and elements would separate out and maybe it would form an atmosphere from the water in the elephants and we would have a new planet or moon to escape to. So thats the impact of this AP on my life, its just grrrreat!

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.



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.
