Do you have any specifications about the desired sample rate? number of channels? voltage range? precision?
The (stock) IOIO can do up to 16 concurrent channels at 1kHz each, 10-bit resolution, where each channel is 0-3.3V. With some firmware tweaks you can increase the sampling rate, and even more so if you're willing to trade-off the number of channels. If you want different voltage levels, you'd need some analog front-end. If you need higher resolution, you can use an external ADC. In terms of software, you'd need to write a piece of Android software that reads the (buffered) samples and draws them to the screen. What's you're describing has been done several times in the past. Some of it might be open source. Google it.
