Archimedes Calculator

Archimedes is the graphing calculator reinvented for the 21st century. It’s much simpler yet more powerful, made with attention to the tiniest detail.

FORMULA LIBRARY (PREMIUM)
Archimedes is one of the first calculators to feature an inbuilt formula library. It’s as simple as picking a formula and filling in the variables. The answer is calculated automatically, and even units are fully supported.

PLOTTING (PREMIUM)
Intersecting, integrating and finding derivatives should be intuitive and straightforward. Archimedes lets you interact directly with plots and makes it all as easy as dragging your fingers across the screen.

EQUATIONS
Archimedes is backed by a powerful mathematical engine. Equations are solved automatically and can be shown in both exact and numeric form, and even systems of equations are supported.

Perfect by all means
sirwankamal

They keep saying nothing is perfect but that is because they haven’t come across this calculator. Worth every penny, don’t hesitate to use or buy it.


Good, but limited.
Suchir Kavi

No way to do systems of equations, integrals, derivatives, combinations, permutations, etc. Not a CAS for sure. A fancy scientific if anything.


This is the one

I have tried many other calculators, but they are all hot garbage. This one has no ads and has a great and intuitive UI. It also allows you to solve equations. Suggestions (i might add more later): * Easier way to copy results with the ability to round the result before copying * Don't dim the previous calculations because its hard to read * Custom variable letters * Change the "contradiction" message to say "no solution" * Color code the vaiables in the result when doing an equation


Almost the best
AveLeon

Great calc app! It’s only missing themes! Same color buttons make it a bit hard to work.


Great Product

Not many calculators can do what this one does. It’s has very friendly user interface unlike one line calculators have. It gives you answers as a decimal or exact form. It can solve for variables.


By far the best calculator app I have ever used
Trog White

Little more to add. It does everything you want for an advanced calculator without being cluttered.

App keeps asking for my Apple Id password


Amazing, with a few small holes
ethanmoroniwalker

I love this app. I’ve used it for years and it has some features that i seriously enjoy. It lacks a few features that, if added, would put me over the edge to buy the upgrade. I really want a factorial button (doing the multiplication “by hand” is annoying). Along with that I want a permutations (nPr) and a choose function (nCr), this would make calculations related to statistics much easier. I’m thinking about buying the upgrade now, but if those were added I would buy it right away!


too dark

the history is too dark to read in sunlight


Fantastic, complete, but abandoned?
Jake Ewing

I’m a senior in college majoring in aerospace engineering. This calculator is fantastic for doing my homework but could be improved. Specifically, the CAS needs improvement but is adequate, most things that I cannot solve with it, I can use the plotter to solve for me. The equation list needs the ability to add and edit equations with units being available for computation not involving the pre-baked list, it would be great if I could save structural and aerodynamic equations so that I could search through them. That said, this is still the most complete calculator app that I have found on the App Store so far. Unfortunately though, the app seems abandoned. The developer’s email address does not accept emails, the website is down, the iOS app has not received an update in two years, and the android version has disappeared. If the developer reads these, please open source your app if you do not plan to continue development. I am sure someone else who is technically inclined would love to continue development for you on your behalf.
