Design, fill, and verify down-insulated gear with engineering precision — all offline, no account required. Clyven is the workbench companion for hand-builders of sleeping bags, quilts, puffer jackets, vests, duvets, and down booties. Enter your piece dimensions, chamber count, construction type, shell fabric, and fill grade, and the built-in LoftEngine instantly calculates the exact grams of down to load into every baffle chamber. Back-solve from a target comfort temperature to find the loft you need before you cut a single seam. Every calculation runs on-device — no internet, no subscription, no data sent anywhere. The fill catalogue covers 12 real-world materials from Hungarian goose 850 to recycled down 600 and two synthetics, each with IDFB and EN 12934 fill-power figures.

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 6 screenshots above are Clyven's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Clyven runs a dark set where the background shifts from screenshot to screenshot (first shot #34244C) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #FC0404, 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.
