There is something very similar, but not open, available for iPad, called MiRack[0]. It was a great help to me in figuring out basics like VCO/LFO/ASDR/VCA. Virtual modular isn't going to sound quite like real analog but it's a great way to learn and experiment at very low cost. I have promised myself to get VCVRack working before I spend any real money on modular gear. [0]: https://mirack.app https://mirack.app
