What better calculator can you get?


No updates....

I loved this calculator so much but the latest update was 2 years ago... still no support iPhone X.... :(


Great calculator app! Still has a few bugs

montesomething

I love this app as a calculator and it has completely replaced my calculator app for physics and more advanced math. It just has a couple of small issues like on the graph when you trace it never seems to quite find the intercept exactly, instead showing a super close number in scientific notation (floating point issue?). Also as other reviewers have mentioned, adding matrix features would definitely bring this app to 5 stars


Missing a key function

the toxmeister

This app, like many other calculator apps, is missing an important button that even Apple's free included calculator has. That is a ± button. Does nobody enter negative numbers any more? Anyway, I don't think the developer exists anymore. Clicking on the App Support button takes you to a DNS search page.


Looks like developer has abandoned it

Great product but no updates. No iPhone X support.


Amazing App

I love this app. Anyway to save my own formulas?


Trigonometric functions are broken

banesullivan

Be warned if using this for academic or professional applications. The trigonometric functions do not output correct values regardless of use with degrees vs radians. This calculator states sin(140deg) = 0.681807 where google and my TI-83 state that sin(140deg) = 0.642788. This can result in very significant percent errors if using trig functions for intensive calculations. Also this calculator states sin(pi/2)=sin(90deg)=0.999439which should be 1.0


Superb, trig functions work

Snookie Gooch

A previous review stated the trig functions are incorrect. Not so. I have a TI-83 as well as Archimedes, both give the exact same result for sin(140). I really like this calculator, don't ask me why but I collect them. I have about 20. If I ever decide to delete all but 2 or 3, Archimedes would be one of the keepers.


Use this 9/10 times over my Casio

I'm a practicing electrical engineer and I use this app every day without fail. The interface makes setting up (and editing) a calculation easy and fast. Get it. Well worth it.


Fantastic

Rueben_Sammiches

A really wonderful calculator. I love the inline editing. Not only does it function really well it looks wonderful. I emailed the developer suggesting a few features (like !'s) and they responded promptly and kindly. Haven't seen the features come out yet but I still hope for them because they will complete an already amazing app. The only thing I feel that is a major lack is that it doesn't have a simple apple watch app to pair with it.
