Description
Reboot a 70's retro design classic! RetroFX is a remake of the Casio fx-39 scientific calculator, complete with moving switches, keys, sound and an authentic, "green" vacuum tube display, beautifully rendered in amazing 3D.

* Rotate 360, turn, scale and move in 3D with your fingers.
* Green screen, 7 segment display with adjustable glow.
* Buttons physically press with sound.
* Move the mode switch with your finger.
* Even the on/off button works!
* High resolution modelling.
* Tilt affects light reflections.
* Looks awesome on a pad.


RetroFX is based on the Casio fx-39 from 1978 made in Japan. Casio made many models with this very popular case design, but functionally, they were all slightly different. The RetroFX display is a reconstruction of the popular green Vacuum Fluorescent Display (VFD) which is actually a small cathode ray tube. RetroFX recreates the original glow given off by these tubes which would typically vary depending on battery strength.

Comments on 3D Calculator RetroFX for Android

★★★★★ Red Frog · May 5, 2019
I love this. I don't really even have a use for this one, I just bought it because I like the free one so much. If you've tried the free 3D calculator from the same developer, you can expect a similar experience with this one. The calculator is nicely modeled, featuring animated and functional buttons and switches, buttons and switches click appropriately. Program options include lighting, vibration, and adjustments for the display's glow. This one even shows a battery door on the back.
★★★★★ A Google User · Jan 25, 2013
Exactly like the original I had one of these, or similar model at school. Best looking calc app!
★★★★★ Emmanuel Nalundasan · Apr 21, 2025
Very useful for me. I would suggest though in its setting for a button to lock its display on 3d or 2d to avoid accidental tap and change of display format. Thanks 😃.
