## Most critical reviews (10 lowest-rated)

### 1/5 — Not fair

*2026-04-13*

Difficulty for shutdown this app

### 1/5 — Not free

*2026-04-11*

They try to charge you once you download it

### 1/5 — TVM requires payment

*2025-09-16*

The one reason you want an HP 12C is to do TVM calculations this app won’t do them unless you pay for the upgrade.

### 1/5 — Misleading

*2025-05-13*

Forget this app!  They make you believe it’s free but as soon you want to perform a calculation, it asks you to upgrade.
Just by the real app from HP.  No gimmicks there!

### 1/5 — Not Free

*2025-03-09*

Free to download but forces a paid upgrade right when you try to do any financial calculation

### 1/5 — Tem que pagar

*2024-06-02*

O design é bom, porém, tem que pagar para usar várias funcionalidades, como PV… Então apaguei, pois assim não me adianta.

### 1/5 — Funções pagas

*2023-03-02*

tudo pago, horrível

### 2/5 — Design não ajustável

*2023-07-12*

Eu fiquei feliz de ver uma releitura do design da HP 12 C. Mas infelizmente o ajuste de tela no meu iPhone e oito ficou horrível. A ideia foi boa, mas a adequação a tela ficou a desejar

### 3/5 — Outros idiomas

*2026-01-08*

Querem cobrar para utilizar qualquer conta simples, mas deveriam colocar outros idiomas como o Português, espanhol e etc.

### 3/5 — Cool, but…

*2024-12-04*

It works but I don’t get the difference between the free and paid versions. Also, is there any way to make it work in portrait mode?

### 5/5 — RPN Calculator

*2024-07-06*

Easy one the nicest RPN calculators to work with. Has all HP functions including the % key. Great job.

### 5/5 — Great

*2023-04-08*

Just miss the portrait mode, otherwise it is like my beloved hp 12 c.

### 4/5 — How do u exit program?

*2025-02-27*

Like program been using a hp12c for years.     It is very hard to exit program.   Scipe the screen it take 5-6 times to exit

### 3/5 — Conditionally Great

*2024-02-20*

This is an extended app version of the awesome long-service financial calculator hp 12c. One substantial limitation is that upon closing the app, the program and all saved values (registers) are lost. This is a major issue in my view. For the basic calculations, the app does very well.
