Kairo vs Outread
Both stand on speed reading apps. Which one you can start free with, which one lets you read the code, and what each costs once you pay.
Free plan Android
Kairo combines file-based reading with adjustable standard and accelerated modes, while keeping library data on the device. Its DRM-free requirement and lack of scanned-PDF support narrow which documents it can handle.

Outread combines two pacing modes, adjustable display settings, and reading exercises with several ways to import content. Its file support excludes DRM-protected ebooks, and AI tools have device and operating-system requirements.
