NumWorks Graphing Calculator 4+

This app literally emulates the real-life NumWorks calculator. I already think that calculator is a 9/10.

However, I’d really like to see this app implement haptic feedback. I’m a novice developer, and I don’t think it would take too much time or effort to attempt an implementation of haptic feedback.

When we tap a button on the emulated calculator, it should make our phone click (like a button). I also believe this would improve the experience and efficiency of using the app.

I have some examples of apps that do this well, specifically being Kalkyl by nordic io and Lights Off by Steven Troughton-Smith. Both of these apps include real-life-inspired buttons, and include a realistic-feeling haptic feedback system.

Other than that, there’s not much else to say about this app. It’s just the NumWorks calculator, which is already a 9/10.

Yes, this is a great one and is free. And the idea is to give you the look and feel of their $100 worth physical calculators, so it doesn’t utilize space very efficiently, or for that matter, is not ‘touch screen’ - you touch the buttons on the interface. But yes, I would like to request the developer to change the form factor suitable for phone and tablet screens if possible. I would love to buy one, just that I don’t have a use case to buy the $100 worth device. So I am quite happy with what they offered me on ipad.

This is wonderful. Would be even better if the keys have a pressed/highlighted state upon pressing/highlighting.

Update: found out they have a physical product. Had to buy that because I just can’t stand the keys on the phone version. The web simulator works better.
