General information

New! This app is a photorealistic simulation of the "Schulrechner SR1", a pocket calculator made in GDR (German Democratic Republic / East Germany).
Compared to the original calculator only the frames around the entire device and around the display were reduced for reasons of space.

With the "Calculator SR1 pro" you enjoy a completely ad-free version of the app and support the further development of this project.

The app comprises numerous of frequently used functionalities and obeys the "order of operations".
The keys give optical (key color), acoustic (key sounds) and haptic (vibration of the device) feedback.
Furthermore, the back and an interior view of the original calculator can be displayed (completely without function ).

The "Schulrechner SR1" was a pocket calculator with a liquid crystal display (LCD), which was manufactured by VEB Mikroelektronik "Wilhelm Pieck" Mühlhausen (Publicly Owned Operation Microelectronics "Wilhelm Pieck" in Mühlhausen / Thuringia).
The SR1 was subsidized for students and identically distributed on trade as "MR 609".
It was produced from the early 1980s and used in schools since the school year 1984/85.
The books for teaching mathematics in the GDR referred to this calculator.

Features:
• Basic arithmetic operations: Addition, subtraction, multiplication, division and the calculation of powers (the order of operations is observed!)
• Root, square, percent and reciprocal functions
• Trigonometric functions: sine (sin), cosine (cos), tangent (tan), as well as the corresponding inverse functions arcsine (arcsin), arccosine (arccos) and arctangent (arctan); angles can be entered in degrees (DEG), radians (RAD) or gradian (gon) (GRD)
• Logarithmic functions: Natural logarithm (ln) and commomn logarithm (lg), as well as their inverse functions (i.e. power to base e and 10, respectively)
• π (Pi)
• Memory functions
• Exponential representation

Operation notes:
• By tapping the display, the displayed value 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.

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

Use the Calculator SR1 pro as your daily tool for all your calculations!
