About this app

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.

Looks great and works just like the fx39 in my draw at home (but with a more reliable + button). Dump the distracting rotating gear icon in the top corner when in full screen.

Looked perfect on my Note 3, but the 3D bits and pieces, shadowing, etc, looks terrible on Note 4. Needs sorting out...
