Retro 15C

I’ve been using this for many years in my work. Love it. Except, this week, the entire screen started to blink. Is there a fix?

If you know, you know…

Near perfection. The only thing I wish they would do is to add haptic feedback on the keyboard. Well done , guys.

Just like the original calculator that I used as I got my PhD in physics. The best by HP.

After a few bumps with the loss of a home button, this is back. Thank goodness!

Good job future-proofing the app!

I love this app. One minor issue is that with the loss of the home button, it’s not so easy to close the app. It’s hard to get the skinny bar to turn white. I’d also like a click sound when I touch a key.

This is still my default calc in my iPhone. I even deleted the iOS calc !!!!

I absolutely love this calculator! I started with a 25c for electronics. I now have an 11c and a 16c. This is my favorite go to calculator now. It is perfect for RPN users. Love it, love it, love it!

Been using this app for years, you could always close it by swiping it off the screen. Once it’s on an iPhone with no Home button, you can’t exit the app. The only way to exit the app and get back to the icons is a hard off (power + volume up button)
