Apps and websites conducive to four card systems?

Does anyone know android apps and websites, preferably free, conducive to four card memorization systems (showing four cards at once) apart from Memory League. Offline apps will be very nice​:face_holding_back_tears:

I want to make use of the Jan Zon system.

Does this work for you? Flashing Random Playing Card Generator | Art of Memory

I can make it work offline later today. Let me know if you want any other features.

Edit: I just realized that it doesn’t work on mobile with four cards. I’ll fix that.

Thank you so much for this, I didn’t know that this existed​:smiling_face:.

It flashes 4 cards on android but not in the way you would want for memorization (the cards are shown in a vertical manner instead of next to each other). The timer doesn’t seem to be able to be set to 2 to 9 seconds or 0.2 to 0.9.

There is also the lack of deck reconstruction and automatic marking but if this is extra work, you can ignore this part (this is my lowest priority, I could even take it the way it is at this point).

Thank you again for this website and your speedy response.
