All-Access unlocks paid website content such as readers, labs, simulators, calculators, design tools, system builders, practice exams and professional programs.

How can I restore website All-Access?

How can I restore or transfer a purchased Web App?
Open My Web Apps, select the app and enter your Stripe purchase email and the private recovery code shown after payment. This registers the current browser/device and replaces the previous device’s online access for that app. No account or emailed sign-in code is needed. If you lost the recovery code, contact us with your purchase receipt.
Are the apps free?
Current prices, availability and included features are shown on each Web App purchase page and App Store listing. Browse the Apps Catalog to choose the available format for each app.
How do I report a problem or request new content?
Email us with the app or page name, what you expected, what happened, and your device/browser or app version. A screenshot can help. For purchase issues, include the purchase email and receipt or transaction reference. We also welcome suggestions for new apps, tools, lessons and improvements.
Where can I find books?
Browse the Books catalog for available titles and their Amazon or Apple Books listings. Formats, prices and regional availability are shown by the relevant bookstore.
Apps with AI support
Apps that use AI for enhanced features require you to enter your own AI API key. AI usage may incur additional charges from your AI service provider. This applies to both Web Apps and iOS apps.
