Publishing guide
Create a Book App Without the App Store.
Give readers an app-like book experience without native app submission.
The practical difference
Native apps normally require store accounts, review processes and platform-specific packaging. An InstallableBook uses modern web-app capabilities so readers open a link and can save the book to their Home Screen.
Which should you choose?
It is not an App Store application. It is an installable web reader delivered directly from the web.
InstallableBook is additive
Many publishers can use an InstallableBook alongside PDF, EPUB, Kindle or print editions rather than replacing every existing format.
