Both versions run on device. Speed depends on your device and content; Pro does not speed up the speech engine.
Does listening start as soon as I import a book?
FolioTone preserves the pages in your PDF. After importing, open your book and tap “Listen from page start” or “Listen from here”. Continuous listening moves through the following pages, with optional automatic page turning.
Do I need an internet connection for speech?
No. Text extraction, OCR and speech generation run on your device. Internet is needed to download the app, purchase or restore Pro, and retrieve books stored in cloud services.
Can I listen to scanned PDFs?
Yes. The app attempts text recognition on pages without a text layer. Accuracy depends on scan quality; review and edit recognized text before generating audio.
Will playback continue with the screen locked?
Prepared audio can keep playing with the screen locked. For longer listening, use “Prepare & export audio” first; speech generation needs the app in the foreground on iOS.
What does “unlimited” mean?
The two free voices have no daily character quota. The other six voices allow 3,000 characters of new audio a day on Free; Pro removes that quota. Generation speed and individual part length still depend on your device, memory and available storage.
Does Pro generate speech faster?
Both versions use the same speech engine. Pro removes voice quotas and batch limits. It is a one-time purchase; your local App Store price is shown in the app.
