The free plan is available on mobile and web. Premium adds full-text, author, notes, and other advanced search options, uninterrupted listening playlists, and reading insights covering read rate, peak reading time, categories, and popular sites. PaperSpan says it has no ads or tracking. Premium costs $8.99 per year through an auto-renewing subscription, with price variation possible by location. It renews unless canceled at least 24 hours before the period ends, and cannot be canceled during an active period.
