My Picture Books

Some stats:

• 873 ratings, a 4.5 rating on Google Play
• ~20K active devices
• In app purchase for FTP connection and to sell some books sell roughly ~$5 / week.

There is a way to share books online:

• No account (or costs) required.
• You get a unique link to post a book to.
• Everyone is moderator (except me). So if one person flags the content it goes offline.
• Per month there are ~800 books uploaded, and ~5000 books viewed.

It's used all over the world, in schools, by kids and adults. For some reason it seem to do well in France.

The little income it provides balances out to the little costs I make. The app requires hardly any maintenance, except updating libraries.
