Title

Just stopped working. When I open an epub, it’s just blank.
Shame.

Jank

Just a wrapper around the ttsu reader (and not that great to be honest). It’s janky and this especially does not work well on a MacBook.

Best Japanese reader for ios with some minor caveats

This is the best simple reader app for Japanese if you are a more advanced Japanese learner whomdoesn,t want much more than to display a book and have a nice dictionary. The only things I wish it had are continuous scrolling mode like the browser version of the ttsunreader that it uses. And also when you delete a book, the statistics should be deleted. Because when you add a new book ttsunis going tomuse the lowest available ID and then the statistics for multiple books get all garbled up. Similarly, if you skip to another part in a book, maybe because you read a certain amount in another app or debice, it is going to skyrocket the reading speed stat.

Great! With a couple small gripes

I much prefer this to the bloat and confusion of Manabi reader. It would be absolutely perfect to me if there was iCloud sync for the books you’re reading and where you are in them. There is that one issue where when you swipe out without pressing the bookmark button it doesn’t save your spot, but it doesn’t bother me too much. Haven’t tried the premium browser within, so I can’t speak on that, but I may try it in the near future. Thank you for developing this! So so useful to have these tools on iOS.

Saving broken

Book position no longer saved and developer is not responding to bug reports via email. Additionally the app overheats easily and saps battery life.
