Reply to any chat from a screenshot, fix every mistake and see why, and write emails and letters in seconds β€” with an AI keyboard that works in every app. QuietType runs on Apple Intelligence inside your iPhone: your words never leave it. REPLY TO A SCREENSHOT Screenshot a conversation in WhatsApp, iMessage, Instagram, Messenger or email. QuietType reads it on your iPhone, works out who said what, and writes three replies. Pick what you want to say: agree, decline politely, ask a question, apologize, be funny or flirty, follow up, or say no firmly. THE QUIETTYPE KEYBOARD Keep your usual keyboard. When you want help, tap the globe key to switch to QuietType and use Improve, Fix or Reply right inside Messages, WhatsApp, Mail, Notes and any other app. No copy and paste. FIX MISTAKES AND SEE WHY Grammar, spelling and punctuation, corrected with the smallest possible changes. Every change is highlighted with a short reason, so you learn as you write.

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.
