Classic Calculator Free is an Android app developed by TCY SOFTWARE ENTERPRISE. It is a reliable calculator suitable for everyone. The app offers a 16-digit calculator with 99% of the functions similar to the original classic calculator. With its HD theme, users can enjoy a clear and crisp display. The app guarantees 100% error-free calculations.

One of the unique features of Classic Calculator Free is its special functions. The app has four memory functions: M+, M-, MR, and MC. Users can add or subtract the current value to or from the stored value in the memory register. They can recall the current memory register value or clear the memory register (set to zero). In addition, the app has a C/AC function that clears the screen and also clears all when pressed twice. Users can also long-click on the screen result to copy it.

It is important to note that users can change the themes by long-clicking the M+ or M- button. They can also change the mode (vibrate or silent) by long-clicking the % button. Classic Calculator Free is a free app that requires a quad-core 1.0 GHz processor and 2GB RAM for optimal performance.
