The new Kindle Self Publishing App for Windows Phone has hit 1 million monthly users, making it the first app to hit the milestone in the app’s history, the publisher said on Thursday.
Kindle Self Publishing, which launched earlier this year, now has 1.2 million monthly active users.
Wiley Publishing also said that the app will be available in the UK and US later this year.
Kindles launched in December 2016 and currently sells for around $299.
The company plans to expand its product line in the coming months.
