WhizKid · App Store Screenshot Kit

Builds complete App Store screenshot sets at Apple's exact pixel sizes and exports them ready to upload.THREE DEVICE SIZESiPhone 6.9" (1320 x 2868), iPhone 6.5" (1284 x 2778) and iPad 13" (2064 x 2752), built and exported at 1x so nothing is ever scaled or rounded. Alternate accepted sizes are selectable. Apple caps a localisation at 10 screenshots, so the panel count is capped there too.ONE CONTINUOUS BACKGROUNDThe hard part of a screenshot strip is artwork that runs across all ten images. Instead of ten frames to align, a single full-width BG Band component is instanced into every panel at a negative offset, so each panel is a window onto the same unbroken artwork. Edit the band once and all ten update. An FG Band does the same above the panel content, which is how a device or a character can span a panel boundary.LANDSCAPE DEVICE MOCKUPSTwo stacked per phone panel by default, since a landscape mockup only fills about a fifth of a portrait screenshot. Swap the real device art into the component once and every panel follows.LOAD A SETPoint it at a folder holding set.json and its assets, and it fills background artwork, headline copy, app captures and character art across all three sizes in one pass. Captures map per panel, and a panel can give its stacked devices different captures. Reloading is safe: art it placed is cleared before the new pass, and a spec that stays silent about a size leaves that size alone.VERIFY AND REALIGNVerify checks every panel against the spec: exact size, integer position, export locked to 1x, band alignment, and an opaque backing fill so no alpha reaches Apple. Realign snaps anything that drifted back to the grid.EXPORTEvery panel at 1x, in order, named per device folder, each checked against its spec size, delivered as a single zip. Guides live outside the panel frames so they cannot appear in an export.
