No RPN. Neckbeard status confirmed. Calculators are still an unsolved problem for me on glass devices to the point I still religiously carry around an HP50G even though its 6x the size of my phone. Also from some bad experiences, it appears that some "app" calculators are also seriously badly implemented. Even basic trig ops can return stupid values at extremes which makes them untrustworthy. Plus none are reasonably…

Couldn't agree more. I regularly use a HP12c, HP48 and HP50G. However, the emulators for all of those are really quite good (for hp12c, get the one from RLM Tools), especially when ran full-size on an iPad.

I am glad to see this effort because we really need some innovation in the world of calculators. The science of making them has stagnated in the late 1990s. HP50G isn't really different from HP48, first introduced in 1990.

I think there is a widespread perception that calculators are no longer needed, because we have all those computers around us. But that simply isn't true. Many people still need to calculate things quickly, and that requires a good tool: a calculator with a well designed user interface. This is where most devices and programs fail. HP worked on this for more than 20 years and got really good at it, until the unfortunate reorganizations that got rid of the calculator division.

I can't think of any other tool that will let me equally easily multiply numbers, convert hex to decimal, work with complex numbers, and compute a Laplace transform.

And even if you are in front of a computer and have a powerful mathematical package available, there remains the problem of the user interface. For example: I use Mathematica for lots of things. But just try entering numbers using engineering/scientific notation: 4.7*^-6 and you'll see this isn't good at all for rapid calculations.

I hope that someone will start where HP left off and design a better calculator using the huge computational power that we now have at our disposal. Without throwing away all the experience we already have.

Yes. I really want a decent, pretty, RPN calc on all the platforms I use. Which rules out any HP emulator. I've got several amazing HP calcs gather dust in a drawer; I want something better than that. I've been pleasantly surprised with the built in calculator that ships with OSX; it's got a decent RPN mode, good keyboard support, and a nice stack display. Not brilliant, but better than what I've found for Windows or…

Actually, I found HP emulators to be really good.

On my iPhone, I use HP-12C emulator from RLM Tools (I found most other emulators to be inferior). When I really need it, I use HP50G.

On the iPad, I use either m48+ or HP50G (it seems to be another fork of the emu48 code). Both work really well given the size of the iPad — very comfortable to use.

Handsdown it has pretty good ui. But i regret buying it, because i can't calculate % seriously why isn't on the front. I have to press folder button to find it.

additionally, I am baffled why do i have to press = to find end result, it should automatically calculate as i enter figure just like my $3 citizen calculator does.

Great to see more people attacking the underserved math app segment on the iOS. I'm the author of Scalar ( http://scalarapp.com ), another calculator replacement for iPhone / iPad. Just tested both versions of Tydlig very heavily, looks like the author ran into lots of the similar math/UI problems as I did when I was working on my app. :) Some approaches he has chosen look similar, some are unique. Great work, good l…

How does your app compare to Soulver?
