Bolek Calculator pro

Bolek - Một máy tính đẹp và đơn giản trong thiết kế của những năm 70

New! This app is a photorealistic simulation of the Polish pocket calculator "Bolek".

With the "Bolek Calculator pro" you enjoy a completely ad-free version of the app and support the further development of this project.

The app comprises frequently used functionalities and obeys the order of operations (unlike the original pocket calculator).

The keys give optical (key color), acoustic (key sounds) and haptic (vibration of the device) feedback.

Furthermore, the back of the original calculator can be displayed (completely without function! ☺)

The Elwro 441 "Bolek" was a pocket calculator with an LED display which was manufactured by "Wrocławskie Zakłady Elektroniczne Mera-Elwro" in Wrocław/Poland (about 1978/79).

Features:

• The 4 basic arithmetic operations: Addition, subtraction, multiplication and division (the order of operations is observed!)

• Root, square, percent and reciprocal functions

• Memory functions

Operation notes:

• By tapping the display of the calculator, the value displayed is copied to the clipboard (and is available for further use in other apps).

• Swiping from the left edge to the inside, the menu is displayed:

Here you can find among other information the settings for the sounds played by the app and the vibration.

Use the "Bolek Calculator pro" as your daily tool for all your calculations!

The "Bolek Calculator" is part of a series of historical pocket calculators: The two others are Calculator SR1 and Calculator MR 610.
