Need A Calculator App For iPad?

This is the one! I thought a calculator would be standard issue on any Apple product. My iPhone had an app installed and I was somewhat disappointed my iPad didn’t. I liked the one I was using on my iPhone and looked and looked for it for the iPad finally finding this. I didn’t even realize all the extra functionality was available on this app until one day I accidentally turned my iPad onto the side in landscape mode. It’s worth the small fee in my opinion to get the pro version. I don’t think you’ll be disappointed but, check it out yourself!

Great App!!! 👍🏻

Hi, Im Justin, a 6th grade student. I started learning algebra 3 months ago and this calculator helped me a lot. It includes all kinds of formulas for algebra and helps me understand. I tried other calculator apps, but this one is the best! The only thing is if there is a help sheet to know what which button does what. At first when I wasnt good at algebra, i didn’t know what each button meant, so I hat trouble. Hope you response. But still a GREAT APP!! Thank you! 👍🏻👍🏻

If your working with money don’t get this calculator!

Hi! I was looking for a calculator app for my new iPad I found this as my first option. I have been using this for a few months with no problems but just recently I got a gift card from someone in my family so I was keeping track of how much I had then the next day it deleted my total!! So I thought I had a good amount of money so I was buying stuff and come to find out my card didn’t have enough!! So now I owe someone a good amount of money! Maybe for a update you should make the amount save that would be a big help for other people to not have the same problem as me!
