Ratings & Reviews
- This app hasn’t received enough ratings or reviews to display an overview.
Text↔audio sync has been rebuilt from the ground up — jumping between reading and listening is far more precise, and you stay in control.
• You decide when to jump: two new icons at the top of the reader replace the automatic jumps. The waveform icon brings the text to the current listening position, the headphones icon starts playback right at the passage you're reading. A one-time note in the app explains this after the update.
• More precise jumps: the text matching between e-book and audiobook has been completely rebuilt and now finds the right spot with sentence accuracy — even in long books.
• Abridged audiobooks are detected: if the audiobook is an abridged version of the e-book, the app tells you once. Jumps work wherever the text exists in the audio.
• More reliable sync between iPhone and iPad: position conflicts are detected cleanly and resolved via a dialog instead of being silently overwritten.
• Apple Watch syncs on open: the Watch app now fetches the latest position from iPhone and iPad as soon as you open it — not just when you press Play.
• Widget shows reading progress: if you're only reading, the percentage in the home screen widget now follows your reading position.
• Correct chapter and total durations for MP3 audiobooks with variable bitrate.
• Faster and more stable: text search and chapter matching run many times faster, a possible freeze when opening the reader has been fixed, and switching the audio format inside a book folder (e.g. MP3 to M4B) is now detected cleanly.
