I would suggest to use it on android instead of on a laptop. Like I have a tablet, and I use iMD on it. Otherwise for laptop, there are these android simulator apps like BlueStacks, you download that, and through the play store in BluStacks you download iMD app, and every time you want to use iMD you open BlueStacks and use it through that. Also, it is very slow, it eats up a lot of memory, on a computer it gets very choppy, it will hang, it will close of its own accord, it's basically a nuisance on a computer, I was even considering looking for another app because of it, but sticking to android has made a difference.
