Web Apps FAQ
Purchases, installation, recovery and AI support.
What is the difference between the Web App and the iOS app?
The Web App and iOS app versions of the same app share the same core features and the same interface. Web Apps run in a compatible browser on iPhone, iPad, Android phones and tablets, and Mac or Windows computers. iOS apps are installed through the App Store on supported iPhones and iPads.
How to install Web Apps on iOS and Android devices?
On iPhone or iPad, open the Web App in Safari, tap Share, then select Add to Home Screen. On Android, open it in Chrome, tap the menu, then select Install app or Add to Home screen. You can then open the app from its Home Screen icon.
How can I restore or transfer my Web Apps?
Open My Web Apps, choose 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. Save your recovery code privately; email alone does not unlock a purchase. Contact us with your receipt if the code is lost. Local projects do not automatically transfer between devices.
Can I use Web Apps offline?
Yes. After purchasing and opening the app online, select Prepare offline in its app toolbar and wait for Offline ready. Local features then work offline. Payment verification, restoring or transferring access, and AI generation require internet. Browser storage cleanup can remove offline files and local data. Transfers revoke the old device’s online access; offline copies cannot be remotely erased.
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.
