Can I purchase additional Plagiarism Checker credits if I subscribed using the mobile app via the App Store or Google Play Store?

Currently, we don’t support purchasing additional Plagiarism Checker credits for subscriptions bought through the Apple App Store (iOS) or Google Play Store (Android).

If you subscribed through the mobile app, you cannot buy extra credits either within the app or on the 
QuillBot website.

Plagiarism Checker credits are only available as part of Premium subscriptions purchased directly through the QuillBot website.
