Apple is quite strict about the "bait and switch" feeling. Even though you mentioned the subscription at the very bottom, their guidelines (specifically Guideline 3.1.1) require that if you list features in your description, it must be clear which ones require payment before the user hits the download button. The issue is likely that your "Key Features" section implies everything is free, and the "Unlock the full power" sentence at the end is too vague or feels like an afterthought. The Fix To pass review, you should add a "Pro/Premium" section or use asterisks to clearly denote paid features. Here is a revised version of your description designed to satisfy the App Store reviewers: Revised App Description Transform the way you read and interact with documents.
