Most reading apps give you a list. BookZEN - Bookshelf & TBR gives you a shelf. A timer runs while you read, and every sitting is written into that book's history. Months later you can look back and see how long a book took you, when you picked it up, and what you were thinking while you were in it. Free to download, with an optional Premium upgrade. TIMED READING SESSIONS Start the timer when you sit down, stop it when you get up. Pause for the kettle and come back. Each session records where you got to, so your progress is built from real sittings rather than from guesswork. Run a timer while you read; pause it and return without losing anything Record the page or percentage you stopped at Reading speed worked out from your own sessions Attach a short note to any session — a reaction, a line worth keeping Forgot to start the timer?

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 13 screenshots above are Bookshelf & TBR - BookZEN's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Bookshelf & TBR - BookZEN runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #1C3C2C) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #9C7464, 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.
