About this app
You don't need to reduce your pile of unread books. A reading log and book management app that lets you view your stack of books as a tower | Supports importing reading records from Booklog and Bookmeter.
Read full description
■ Display Towers by Genre Tapping on a "Reading Tower" or "Completed Tower" in the Review section allows you to rearrange them by genre. ■ Custom Genres (PRO) You can create up to three custom-named genres. These can be created from "Custom Genres" in Settings and selected from Book Details or Manual Registration. They won't be overwritten by AI's automatic detection and will be reflected in tower and reading trend analysis. ■ Switch Towers by Tag (PRO) You can also switch to towers based on tags (up to three) selected in "Tower Tags" in Settings. ■ Import Screen Guide Importing from Bookmeter or external services will display the reading limit for the free plan. Importing again after upgrading to the PRO version will not result in duplicate books. ■ Improved Usability The "Reading Record/Book Information" in Book Details has been changed to a toggle switch, and you can now select the first tab (barcode/manual entry) on the book registration screen in Settings. The "Study Room" in the Reading Timer has been renamed to "Reading Space." ■ Bug Fixes Fixed an issue where the numbers in the weekly/monthly letters were overflowing horizontally, and added "san" to the recipient's name in the unreadable text messages.
