At the moment my app on Google play is selling for 0 dollars,
70% of zero is a net profit of 0 dollars.
wait, what? you can actually sell your apps?
doh! missed that boat.
I think it has always been that the most generous big fat companies like Microsoft, Apple and Google have shall we say 'held back' 30% of what you would make on your apps because probably they're poor people living out of cardboard boxes and they need it more than we do
70% sounds about right then.
Although about 84.5% of the people reading this will be 7.1% influenced by it.
