This free app provides live waiting times for the emergency departments (A&E) and urgent care services in Devon, Cornwall and Somerset. NHSquicker provides information about the healthcare services available to you based on your location, helping you to choose the right service and spend less time waiting. The combined travel and waiting times estimate how long it will take you to be seen by each service. Our emergency departments are busy, and often for a minor injury, you could be seen quicker elsewhere. Please remember to always ring 999 in a life-threatening emergency. You can find information about minor injuries units, emergency departments, pharmacies, dentists, opticians, sexual health and GP surgeries. If you are not sure where to go, you can dial 111 and they will direct you to the most appropriate place for your needs. The information feed is provided by Torbay and So…
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 8 screenshots above are NHSquicker's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: NHSquicker runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #ECF4F4) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #045CBC, 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.
