Nonta Afavost is the keycap-set fitting tool built for mechanical keyboard enthusiasts who demand precision before they pull a single cap. Describe your board — layout, sculpt profile, stem mount, stabiliser bar, front height, and typing angle — then select the kits from your keycap set. The solver checks every key position in real time and tells you exactly which keys are covered, which can be substituted within a safe height tolerance, and which ones you will be short on. The live plate matrix draws your board at true unit scale — that 6.25u spacebar, stepped Caps Lock, and two-row Enter are all rendered at their actual widths. Keys are colour-coded by coverage state and update instantly as you toggle kits on and off. Tap any key to see which caps can serve that slot and to allot one of eight sculpted artisan caps. Surplus caps are tracked separately so nothing gets lost in the count…
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 Nonta Afavost's answers to those questions — they're public, they're real, and they made it through Apple's review.
What the numbers say: Nonta Afavost runs a mixed light-and-dark set where the background shifts from screenshot to screenshot (first shot #FCFCFC) — each image has to stand on its own, so the captions carry more of the story. The accent colour we picked up, #FC141C, 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.
