How it works.
iOS version distributes the text on any page of any iOS devices.
Android version - it's just screenshots of text, so it weights more.
To make a sounded book, you must devide the text to the pages and sound engineering manually for each page. The pages are fixed and sounds are tied to the pages. So the user can not change font in the settings.
85% of users read with speed which we suggest. There are 2 tracks of sounds: one-off (which sounds just once while you are on the page: like creaking doors, cough) and background (which repeats during the user stares the page: like wind or rain). The user can change volume of each track. So if he doesnt match our speed, he can switch off one-off sounds and listens to only background track.
Also there are a lot of ideas on how to calculate users speed and change speed of sounds. For example, to test reading of the text. Or by apple of the eye. But we have not implemented it.
How to earn. First of all you must use interesting famous content. While you'll be making sound engineering by your own, use short stories of famous authors. Also you can advice to some famous publishing house the whole technology. That'll increase their sellings. Also - to start fundraising campaugn on Indiegogo or Kickstarter to gain funds for a child sounded book. Firt of all you'll gain funds and earn (and upgrade the code and technology). Second - you'll make an ads to this your book and you as a developer. Also, as for earnings, you can let users to unblock sounds only via in-purchase. Block a half of book and unblock after in-purchase. Earn on admob and on blocking it. And so on.
You just need to fill the books with a famous interesting content.
