The Exam.net iOS and macOS applications is the best and most secure way for students to perform online exams. The app is specifically designed to prevent cheating attempts by students and to provide a distraction-free environment. With the Exam.net lockdown app, students can take exams without teachers having to worry about internet browsing, accessing other apps, or receiving notifications. The app locks down the device and ensures that students stay focused on the exam at hand. The app is easy to use, and students can access their exams with a unique exam key. It is designed to work seamlessly with Exam.net, providing a simple and secure digital exam space for students to complete their exams.
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 7 screenshots above are Exam.net's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Exam.net runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #142434) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #14CC6C, 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.
