Great for the trial

I can’t purchase this app. I tried several passwords but can’t get the purchase to work. What a shame. This is a great app otherwise.

The pressure conversion in this calculator uses seawater. For example, 20 psi is converted to 45.2412 feet of sea water. Using sea water is not common, and the calculator does not provide feet of standard water for a conversion unit. The conventional conversion is 20 psi is 46.1358 feet of standard water.

RPN-15c

Since 1983 I use first HP11c then HP15c. The RLM is a real improvement especially as a programming aid.

Bait and switch!

No price down in App Store, but upon install, immediately demand $9.99. NOPE

Great app

Obviously a work of love from someone who cares. I used an hp15c for most of my working life and this app is a faithful recreation of that experience. With this revision the intermittent lag is gone. Thanks to the developer for quickly responding. I give the app five stars now.

We are very sorry for that, but be sure you are using the same Apple ID used in your first purchase. If it is ok, please refer to Apple's customer support. They completely control the installation, payments and restoring.

“Clear” “REG” doesn’t clear the registers

Great for money, except “Clear” “REG” doesn’t clear the registers. This is a bug that needs fixed ASAP.

This bug was fixed in the latest update. Please update to it (version 2.1.7).

Sehr guter Rechner

Sehr guter Rechner mit vielen nützlichen Funktionen. Die Darstellung auf dem iPhone ist jedoch sehr schlecht. Tasten und Zwischenräume bzw Hintergrund sind übereinander dargestellt! Auf einem IPad ist die Darstellung ok.

Probably you have the "Button Shapes" set to ON in "Display & Text Size" option of the "Accessibility" item in the device's Settings.

This is odd. Please delete de app from your device and install the latest version again.

very good if you change one thing

I like this app very much. Only the timing of the haptic feedback don't work for me. I need a feedbach we I press a key. The app wait until I lift up the finger.

All better now

With my settings fixed, this is now my go-to calculator on my phone. It is a bit pricey, but so was my 15C.

It seems that you have set to ON the “Button Shapes” option in the “Display & Text Size” of the “Accessibility” settings. So, open the device Settings, scroll down to the “Accessibility” item and touch it. Then, touch the “Display & Text Size” item and turn OFF the “Button Shapes” switch.
