Sleep Tracker helps you track your sleep and wake up at the right time. Instead of ringing at a fixed second, the app chooses the best moment within your set time window to help you feel less groggy. Sleep sound recording While you sleep, the app listens for changes in sound levels. It doesn’t record the whole night. Recording starts only when noise is detected, like snoring or talking in your sleep. Fall asleep easier The app comes with a built-in collection of calming ambient sounds and melodies. Choose a timer so the sound would turn off automatically after the set timeframe. Sleep Tracker does not evaluate sleep quality or give medical advice. It simply helps you observe your sleep patterns and wake up more comfortably.
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 4 screenshots above are SleepRec's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: SleepRec runs a dark set with one background colour (#041424) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results. The accent colour we picked up, #3C346C, 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.
