PixelKit is the all-in-one toolbox for designers and developers — a precise unit converter plus a full suite of design, print, and dev calculators in one fast, offline app. No account, no ads, no subscription. It started as the ONLY true pixel converter on the App Store — the only app that correctly converts inches to pixels at 1in = 96px. That precision is still the heart of PixelKit, now surrounded by the tools you reach for every day.

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.

What the numbers say: PixelKit: Design & Dev Tools runs a dark set with one background colour (#0C1424) carried across every screenshot — the listing reads as a single poster when the shots sit side by side in search results.

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.
