### 3/5 — No future value

*2026-08-14, version 3.1.2*

This version of the HP12c will not calculate the future value. When pressing the FV key the response is error.  The app will calculate FV on the IPad 16

### 2/5 — Obscures iMac Screen

*2026-06-12, version 3.1.2*

Emulation is so large it obscures documents on the iMac, which makes this very good performing app unusable on a full-size desktop. Possibly MORAVIA or KOALA42 can add a sizing feature to the menu.

### 4/5 — An overdue but welcome update

*2026-04-12, version 3.1.2*

The history of the official HP calculators is a little bit strange. It started with four - the HP 12C, the HP 12C Platinum, the HP 15C, and the HP PRIME PRO. These all had HP down as the developer, and had zero support and just a few updates in 10 or more years. It's therefore nice to see the rerelease of the HP 12C and 15C with a perfect redesign to suit today's devices. Portrait mode is now supported with the full keypad available. Sadly, the 12C Platinum was simply removed from the store, so I had to buy this 12C. Fortunately the 15C update was free. If you're an HP calculator fan like me, you'll want both the 12C and 15C. It's great that the 12C is also supported on the M-series Macs. It is nice, but I wish at least numbers could be entered from the keyboard. Also sadly, the PRIME PRO has not been updated. It's okay on iPad, but disappointing on iPhone. Fingers crossed that will be addressed.

### 5/5 — Brilliant calculator

*2026-03-21, version 3.1.2*

I have used the HP 12c for years and I am delighted to have it available as an app on my phone

### 5/5 — True to the original

*2026-03-19, version 3.1.2*

It couldn’t be quite as good as an actual 12c but excellent for all that.

### 5/5 — HP 12C

*2026-03-18, version 3.1.2*

As as 39-year user of the original 12C this is a near replica.  All that’s missing is the satisfying soft pop of the keyboard.

### 5/5 — Just like my old friend

*2026-03-07, version 3.1.2*

Fabulous

### 5/5 — 50+ years of excellence

*2026-02-24, version 3.1.2*

The HP 12c has been my go to financial instrument for over 50 years, from my undergrad years and through my business career. The iOS version is an authentic representation of HP’s legendary calculator and a must have for me. Highly recommended.

### 5/5 — Fantastic

*2026-02-19, version 3.1.2*

Love this app!  Once you get used to the reversed Polish notation, it is hard to do 
without.  This app keeps it always available at times I would not ordinarily have my HP -12C

### 5/5 — Misrepresented App

*2026-02-07, version 3.1.2*

Not fully functional.  Tried modification in settings. So disappointed.  No recourse within site. A total loss.

### 5/5 — David

*2026-01-08, version 3.1.1*

Brilliant!

### 4/5 — Excellent- but keyboard is still not as sensitive as before.

*2026-01-07, version 3.1.1*

It’s still missing digits on occasion.

### 5/5 — Top d+++

*2025-12-29*

Excelente

### 5/5 — Modern Convenience of a Classic

*2025-12-25, version 3.1.1*

I used HP12c in college in the ‘70s.  The reverse entry is second nature (like driving stick-shift) and to have it as an app, rather than separate calculator, is the best!

### 5/5 — Made me Money

*2025-12-15, version 3.1.1*

Benn using HP12C since 1981. Used right will make you a huge amount of money. Such a great tool used daily will return 1000’s of % over your career. Need the RE tools to do so contact me.

### 5/5 — Muito prática e funcional

*2025-12-02*

Cumpre as funções da HP12c original , ótimo app para o dia a dia , fora do escritório.

### 5/5 — Perfect

*2025-12-02, version 3.1.1*

I'm a big 12c user from way back. This app is perfect for me and I really appreciate the included help. If you are a hard core finance person you need this app

### 1/5 — Charged for no reason

*2026-07-06, version 3.1.2*

Never opt in to any subscription and got charged 23 dollars - the app was even deleted. Do not download it, it does not show in your Apple subscription and still charging you!

### 1/5 — Terrible enhancement

*2026-05-16, version 3.1.2*

Please tell me how I can go back to the old version. This version is terrible.
Why did you kill store and recall ???

### 1/5 — Ridiculously complex

*2026-03-06, version 3.1.2*

Not for casual user.

### 1/5 — grosse regression visuelle

*2025-09-06*

Cette appli ne ressemble plus du tout à une HP-12C. Merci de remettre le format d'origine avec les proportions de la vraie hp-12c. Comme trop souvent, une mise à jour qui est une vrais regression.

### 1/5 — Don't fix what's not broken

*2025-09-01, version 3.1.1*

The update in mid April 2025 ruined the user interface. I don't know what internals were touch as the numerics seem unchanged.  The previous release gave the appearance of a real 12c. This latest release spread the keys proportionately far apart and the key "names" are much smaller. Who cares about rearranging everything in the portrait mode. It was fine the way it was. If the 15C emulator is change in this way then I will leave the update forever alone. This is a huge disappointment. I bought a new real 12c. It's quite fast but looks the same. That's called improved. I'll just put that in my pocket from now on and leave this emulator alone.  Worse, the money calculations are incorrect.  Verified with an original hp12c calculator, a new one today, and a Mathematica notebook. Even got the r same answers with another iPhone/iPad app.  Very disappointed.  I don't recommend this.

### 1/5 — In decline

*2025-08-20, version 3.1.1*

Don’t keep changing things

### 1/5 — Don’t use it

*2025-08-01*

Not ready to rely on. Bad memory registers. Poor haptics.

### 1/5 — It used to work, but now it doesn’t

*2025-07-28, version 3.1.1*

I used to use this all the time. But now the way it fits in the screen doesn’t show the whole keyboard making it impossible to use.

### 1/5 — New Version Fails in Every WY compared with the previous version

*2025-07-15, version 3.1.1*

You have ruined this App.  The keys don’t work.  The memories erase themselves.  This “upgrade” is an abject failure.  Please return to last year’s version.  Pretty please!

### 1/5 — Major step backwards in design

*2025-06-28, version 3.1.1*

Don't upgrade! This will destroy the entire reason you wanted to use a HP 12c. Note to HP, if this new design is so good, then offer BOTH the older version and the newer design, and measure how many HP-12c enthusiasts uninstall this new version and reinstall the old one.

That is a good way to test this new version statistically.

Again, have a "revert to old version" setting and measure how many people reinstall the older version, because it was so much more usable.

### 5/5 — Latest update fixed my annoyances

*2026-08-15, version 3.1.2*

App no longer resets with every cold launch.

### 5/5 — Solid Upgrade

*2026-08-11, version 3.1.2*

The new upgrade solves all the old bugs! So thrilled!

### 5/5 — Awesome

*2026-08-06, version 3.1.2*

The latest update is awesome. With this app,  it eliminates the need for my physical handheld calculator.  Great work!

### 5/5 — HP calculator rocks!

*2026-08-01, version 3.1.2*

From the days of plug-in to this app! The HP line of calculators are hands down the best! Works great, as well as the original hand held.

### 5/5 — The Best Calculator Ever

*2026-07-21, version 3.1.2*

I have been using an HP 12c calculator since 1985. I wouldn’t use any other. The iPhone version has been on my phone for years. The first version I had on an older iPhone was almost the same size as the physical HP 12c. This calculator has so many features, memories, and programming features. I couldn’t begin to summarize them all. What I can say in conclusion is that once you start using a 12c, you will never change!!!

### 5/5 — At your finger tips.

*2026-07-15, version 3.1.2*

I’ve always had an HP 12c but found myself without it most of the time when needed.  Now, with the App, it always available!

### 5/5 — Outstanding!

*2026-07-04, version 3.1.2*

Brilliant reproduction of the classic 12C! Thank you to the creators - keep it going!

### 5/5 — Just Like The Real Thing

*2026-06-19, version 3.1.2*

I’ve been using an HP 12c since the 1980’s. In fact, I still have my original calculator. But this app is a perfect substitute for when I don’t have my calculator handy.

Couldn’t live without it!

### 5/5 — Decades of Dependability

*2026-04-15, version 3.1.2*

HP12-C has been my single source of any financial or mathematical aid through college in the 80s, through 40 years as a principal broker in real estate, and now in my every day living!  I have Two physical handheld, but rely every day on the app on my iPhone!  HP 12c, you are everywhere I go!

### 5/5 — Muy buena emulación

*2026-03-26, version 3.1.2*

Tuve en mis tiempos de estudio la Hp 12c … y esta emulación me da casi la misma experiencia. La verdad muy buena experiencia de usuario. Muchos recuerdos de mi época estudiantil. Estaba por comprar una original … pero la verdad con esta solución no necesito la física.
