Hey, I'm Knowie - your new way of learning. Whatever you're revising, I'll help you understand it, remember it, and walk into your GCSEs or A Levels feeling ready. 30 million students already study with me, I was created by the best students, and the core tools are free. Here's how the new way of learning works. Everything runs through one place: your exam plan. Instead of a pile of separate features, I pull it all together - flashcards, quizzes, summaries, mock exams, voice practice and your exam board's specification - and structure it into a day-by-day plan built around your exam dates and your topics.

Every shipping app on the App Store has gone through the same decisions you're working through right now: which screenshot goes first, what caption sits over it, which device frame to show, what color the background should be. The 15 screenshots above are Knowunity: AI Revision App's answers to those questions — they're public, they're real, and they made it through Apple's review.

The accent colour we picked up, #3C4CB4, is the one to reuse for badges, arrows and highlighted words if you borrow this look. Hit Use this style to open the editor with these exact colours and drop your own screenshot in.
Notice the first screenshot in particular. It's the one users see in search results and on the product page, and it's where most apps spend their best caption and tightest design. Look at the proportion of background to phone, where the text sits, what one thing the image is trying to communicate.
