Ratings & Reviews
This app hasn’t received enough ratings or reviews to display an overview.
1. Supports direct connection to Yuexingtong X4 for lightweight file management (Beta).
This is an upgraded version of the original “Send to Device” feature. It now supports batch sending of files from your phone to the device, as well as renaming/moving and deleting files. You can also import files into DianMo directly from other apps via the share action.
2. Added controls for adjusting font weight and character/line spacing for TTF fonts (Beta).
After importing a tweaked TTF, this helps alleviate the limitation of the native Kindle reader, where character and line spacing cannot be finely adjusted.
3. Simplified/Traditional Chinese glyph conversion now supports conversion for 2,800+ commonly used Simplified Chinese characters.
4. Attempted to fix several potential bugs on older versions of iOS, and made various improvements to the UI and overall interaction experience.
