Small Download, no Ads

I just wanted a calculator that honestly should have already been sent with an iPad (considering all the bloatware I received but never asked for). This calculator works, it has no adds, and is very small in size. I think 8mb, but don’t quote me.

Thank you for taking the time to build this for people, you saved me some time and money. I figured it was the least I could do to rate it. Keep up the good work.

Perfect essential

Honestly i was dumbfounded when i saw the iPad had no calculator. All these other apps have ads, but this one fits the bill. It gets the job done, no annoying pop-up ads, and small size. Exactly what i need, but i’d like the swipe right to backspace function like in the original apple calculator. Maybe next update add into it? Oh well, Beggars can’t be choosers, thank you nonetheless!!

Good for iPad but a couple flaws

For being a free app it is essential for iPad which lacks a calculator app naturally I recommend it highly. However there are a couple features that I feel need to be improved:

1. Enter in 1➗2= or even 0.5= and the default is 1/2. While you can touch the answer and choose not to simply answer it is weird even in non-scientific mode to see.

2. When an answer is calculated, touching a number defaults to multiply the answer instead of clearing the previous answer. This is odd and the only way to clear is AC (not C as it acts like a backspace key).

3. Certain keys work in weird ways e.g. sin is in natural form but square root works in reverse polish form and displays an odd format (square root of two shows as 2^(1/2) and displays ✔️2 as a result). Either all natural or all reverse please?
