It's a shame they don't know how to make Android app. Galaxy Note is way better tablet for drawing then Ipad ever was. I have ipad but I use note all the time. It lacks good apps like this one but it has a really good stylus.
Related to that, I got really frustrated with the site, I went through all the site (though I didn't watch the video), I read it all, watched the animations, all the way down to the button, where they casually (by ommision) inform me that it's only for ipad, not even a coming soon, nothing, great! I'm not saying build it for every device, but at least try not to totally frustrate me.
I was using the Galaxy Note 10" 2013 model for a year as a substitute of real paper and notebooks at work and at home.
It was too small to substitute the A4 size (~us letter)
Me, a friend, and his friend recently bought a 12.2" Galaxy Note Pro which is almost A4 size and it's just awesome. Those two friends don't use their iPad anymore:
* True pressure sensitivity and pixel perfect accuracy
* Good size and light weight to substitute a real paper notebook
Those are the only two things needed to substitute paper: Decent size and decent stylus. Those wannabe iPad styluses are just trash compared to a good Wacom Stylus for the Note series.
You will know it if you have used both: Crappy iPad Styluses and real Wacom Styluses on a Note Pro.
Most people don't know that each year one single Android device typically sells 10x more than any other one. For ex: Samsung S4 sold more than the next 2nd,3rd,4th, etc rank devices combined.
In addition, the screen sizes are almost all very similar these days. I don't know of a single Android designer or dev who has issues with that. As the UIs scale pretty gracefully. Pretty much the same way web designers adopted responsive design, mobile designers know to expect the UIs to scale/shrink.
Even Apple devices have similar size disparity: typical medium-sized phones, phablet, tablet sizes. And now a totally new watch UI.
The OS versioning disparity on Android is also becoming less of an issue on Android as devices have moved on to 4.0+. As the changes to frameworks are less drastic between 4.0 vs 5.0. Programming is much more predictable than it was say with 2.3 vs 4.0 for example.
