The design is horrible and a relic of skewmorphism.

Single tally memory is useful on small screens. I just wish they’d display the stored value somewhere.

The design is:

1. Not skeuomorphic.

2. Indeed, flat.

3. Almost identical to the iPhone native calculator, except it uses round-edge rectangles instead of circles.

[stevage]

It's skeuomorphic in the sense that the layout is very similar to a physical calculator.

[DrewADesign]

Nope. Skeumorphic design uses ornamentation, like textures and interaction animations, to mimic the aesthetic of a physical object. You don't even need to adopt an existing standard interface layout to be skeumorphic. Make those keys look rubber or give it a mock LCD display and you'd be skeumorphic even if the buttons were in a circle around the display.

It simulates the experience of having two iPhones with the calculator app open next to each-other. iPhones are physical objects.

[joemi]

By that logic, _any_ app is skeuomorphic by default just by existing. IMO that's being too liberal with the definition.

[whywhywhywhy]

No they’re not. Look into the history of the term it’s from the era where your music playing app would function exactly like a CD player.

For example

iPhone calculator is a skeuo calculator because it has the same layout and limitations of a physical calculator.

Soulver is a non-skeuo calculator because it is built around the benefits of a computer and ignores the history of a calculator.

No. No it does not. Does the iphone calculator simulate having an iphone? No. This app juxtaposes two abstracted sets of control buttons. Skeuomorphic doesn't mean "is like something else that exists." The app does not include ornamentation that attempts to mimic the material, motion, structure, or any other physical aspect of the iPhone. If he had a simulated the bezel separating the two calculators or the shine of the glass as if there were two phones physically next to each other, or maybe mimicked the sound made when tapping on the buttons or any other simulated physical feature of the phone itself, then it would be skeuomorphic. That's not the case.

From the second image, it appears he set the cornerRadius too high and the buttons became almonds. If that’s what he was going for, then perhaps it IS skeuomorphic? /s
