For English only – Outread: Speed Reading Review
It doesn't support language like Chinese.
update: downgrade to one star
This app has some pitfalls. For example, the statistics page has a share button, which would prefill not your stats but a bait phrase "My reading stats in Outread" with its purchase link, hooray, such a fantastic promotion method I've never seen before.!
