Description

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.

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.

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

We are very happy about positive ratings, comments and recommendations and - of course - the purchase of "Calculator SR1 pro"

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

Questions & Answers

Q: What is an APK File?

A: Just like Windows (PC) systems use an .exe file for installing software, Android does the same. An APK file is the file format used for installing software on the Android operating system.

Q: If I install an APK from this website, will I be able to update the app from the Play Store?

A: Yes, absolutely. The Play Store installs APKs it downloads from Google's servers, and sideloading from a site like ApkClean.net goes through a very similar process, except you're the one performing the downloading and initiating the installation (sideloading).
As soon as the Play Store finds a version of the app newer than the one you've sideloaded, it will commence an update.

Q: Why ApkClean.net can guarantee APK 100% safe?

A: Whenever someone wants to download an APK file from ApkClean.net, we'll check the corresponding APK file on Google Play and allow user download it directly (of course, we'll cache it on our server). If the APK file does not exist on Google Play, we'll search it in our cache.

Q: What are Android App permissions?

A: Apps require access to certain systems within your device. When you install an application, you are notified of all of the permissions required to run that application.

Don't hesitate to contact us if you have any questions or concerns.

User's Reivew

3 ★Well done. But what a shame there're so many ads. The placement of the one at the bottom completely ruins the app. EDIT: Not to sound cheap, but there are so many problems with paid apps as opposed to donation-ware: (1) because I use a virtual bank, I can't create a PayPal account; (2) I don't have a credit card; (3) can a paid app be transferred to an older phone? (4) other emulators are, well, free (e.g., Free42)... I bet you'd get more money from a donation-based app than a paid one.
