UK Immigration Engagement and Compliance (UK IEC) UK IEC is an official Home Office app for digital reporting and immigration messages. Is this app for you? UK IEC is designed for people who receive digital reporting or other immigration service messages from the Home Office. If the Home Office has not contacted you about the app, it may not be relevant to you. Why use the app? With the app you can receive notifications when you have new messages read and respond to messages in one place view previous messages more easily find information about help and support After you register Once you have registered, you'll receive notifications through the app when a new message is available. Open the notification to view your message and take any action that may be required. Some Home Office communications may continue to be sent through other channels.
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 5 screenshots above are UK IEC's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: UK IEC runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #246CB4) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #64A4E4, 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.
