It's just an observation: for real-world apps, iOS and Android visual styles and conventions are growing closer rather than diverging (and Windows 10 is trying hard to fit into the same mold).
Your observation about iOS vs Android is very narrow-minded, either deliberate or inadvertent. There are profound design language differences between iOS and Android material design. Claiming "flatness" is very shortsighted indeed.
A word on Windows 10, mobile or otherwise. It is indeed a mess, with almost no coherent design language, something that Phone 7, Phone 8 and Windows 8 actually had, for better or worse. Windows 10 throws many of the good design choices for a faux Android look, and a very bad one at that due to complete lack of consistency. Android also lacks consistency throughout, but at least a somewhat coherent design language exists now.
I do not wish to argue here. Do not take my wishes personally. As someone who wishes to only see good technology succeed, and I do not see this as good technology. I do not wish personal failure to anyone individual, and wish you personally all the best.
For a random example, look at Periscope's new Android version -- the differences from the iOS version are minor, yet it fits in nicely on Lollipop: http://www.theverge.com/2015/5/26/8657349/periscope-android-...
As for the "I sincerely hope you fail" part: we're a startup, so we're likely going to fail anyway. Thanks for the honest sentiment, I guess.
