## Most critical reviews (4 lowest-rated)

### 5/5 — Diesen Rechner gibt es von Casio Zeit 1985

*2025-07-01, version 6.4*

Dieser Rechner war als fx-5000 bekannt 

und war mit fx-850 fx-8000 und PB-1000 die Mathe / Physik Sensation für Studenten bis hin zum Professoren und geeignet für schnelle professionelle Gleichungen inclusive 
der Basic Prog. Sprache sowie Assembler 
——- lange Rede kurzer Sinn ——-

KI Robotic —— Casio sollte diese niemals
                           Sterben lassen, solange es
                           Computer und Taschen
                           Rechner und Pockets gibt

### 5/5 — Ara

*2024-07-21*

Very happy user of the app. This app arguably the best scientific calculator app on the store. Developer is very responsive too. I requested a minor UI change and it was implemented within one day. I would highly recommend this app.

### 5/5 — Great calculator for engineering

*2023-01-29, version 4.4*

Great calculator for engineering. I would like to see 7 segment numbers too.

### 5/5 — Classic scientific calculator

*2022-10-13*

Love the interface, which is clear, classic calculator graphic and layout.  It also gives positive feedback when you tap a key.  All this makes it fast and easy to use - what more could you want?  The trig functions all give accurate calculations (unlike another calculator app I had downloaded).  it is also good value to remove the ads.  Nice app!
