Full Range
Worth the cost, especially if you want every possible range of calculators. Scientific, graphing, etc.
Ótimo
Uma calculadora bem completa muito boa!
The BEST calculator EVER!
'Nuff said. It's the best. Get it. Period. Five year later, still best. Get it. Now. Ten years later; still the best and getting better.
Superior Calculator
Given the security risk with being able to unlock iPhone with default calcualtor, deleted, and researched for a reliable calculator. Best phone calcualtor ever- used it to help spouse through college math course…. Better functionality than a scientific calculator… perfect

The best calculator
This is by far the best calculator. It is totally worth the purchase. Please make a Windows app.
Great app!
I’ve been using this app for the last 10 years without any bug. Great job, developers! Congratulations!!
Really nice calculator but..
I like this calculator a lot but there are some odd bits about it. My most frustrating one is trying to find the antilog (base 10) function. You would expect it to be a shift function of the “LOG” button (of which there are 2 off, one on the main screen and one if you swipe left). If you want to find the antilog of a number you need to “Shift and X^n” then enter 10 as the X and the number you want the antilog to as the n. Can we please have a 10^x button on the shift “LOG” button on the next update.🙏

Capable and versatile
Love the range of operations and capabilities (like memory). I have the paid version.
Upgraded to pro in 2017
And using it now and it will not let me use the photo feature i paid for.
review
This is a great calculator and i really appreciate not moving it to a monthly subscription
Very good
But it needs a Control Centre button
Keyboard doesn’t work on MacOS
This is unusable on macOS because not doesn’t accept keyboard inputs
Happy customer
Excellent App for your mathematical need.

Très satisfait
A good scientific calculator app for iPad
I use this app regularly in combination with another calculator app and it’s a good one.
Scientific and Graphing Calulator
A very capable calculator. Takes time to learn how to use all the features.
The Best
I have been using the app for a couple years. It has all you need in any calc. Awesome calculator.
If you need to use a calculator often, it is near perfect!
Buy this if you need to use a powerful calculator often. The small price is definitely worth it since it isn’t a subscription and there are many functions and tools. This helped take off so much homework! I just tested it out and the ai help thing is amazing. Edit: One thing tho, it would help if the equation solver had some feature where you enter an equation and the app figures out what you entered and automatically does the calculation for that equation (but there should still be a way to manually select the equation). It would also help if there was a formula chart in the [?] section.
