The No‑Designer Launch Kit: 7 Contractor‑Ready Visuals a Solo Founder Must Ship (and Exact Briefs to Get Them Done in 48 Hours)

Keep this short for your contractor: list the seven outputs you need and the single conversion goal for each. The store icon is a recognition cue in search and the Play feature graphic / App Store metadata; screenshots are the conversion elevator; the app preview video sells motion and flow; ad frames are your testing atoms for paid campaigns.

Deliverable clarity reduces rework. For App Store Connect you must match device-family screenshot sizes and video specs exactly; Google Play has its own icon and feature-graphic rules. If the contractor delivers correct pixels + a clean acceptance checklist, you’ll avoid multiple rounds of edits and App Store upload failures.

Brief: “Deliver a final app icon and editable source that reads at small sizes and follows platform rules. Provide layered Figma or PSD + exported PNGs: 1024×1024 (App Store), 512×512 (Play); final PNGs in sRGB, 32‑bit PNG (alpha allowed for Play). Keep the mark centered inside a 60% safe area; avoid small text.”

Acceptance tests: open the 1024×1024 PNG on a phone mockup at 60px and confirm the core mark is legible; upload the 512×512 PNG to Play Console's local preview and ensure Google’s auto-mask does not cut important details. If either fails, the asset is rejected.

Brief: “Produce five localized screenshots that tell a single 5‑scene story: 1) Hero + primary CTA message, 2) Core value / main feature, 3) Secondary feature or social proof, 4) Onboarding or key flow, 5) Closing benefit + CTA. Provide source files and exported PNG/JPEG for the largest device family (e.g., iPhone 6.9" at 1290×2796 or current largest Apple class). Use white or semi-opaque caption bars; captions must be short (10–12 words).”

Production specs: supply artboards sized to the App Store’s largest device class so App Store Connect can scale down automatically. Prefer PNG for UI clarity and export at 72–150 DPI depending on platform guidance. Acceptance tests: upload screenshots to the platform preview tool (App Store Connect / Play Console) and verify no cropping, legible caption text, and that the main tap targets/UX aren’t obstructed by the platform chrome.

Brief: “Produce a 15–30s motion preview that demonstrates the main flow from sign-up to core outcome. Shoot clean screen recordings (native recorder) or export from prototype tools at the target device resolution. Add minimal motion titles, a simple music bed or silence, and deliver a stereo audio track (even if silent) because App Store requires it.”

Encoding & acceptance: match the screenshot resolution for that device family, 30 fps, H.264 or Apple‑approved codec, AAC stereo audio, and keep within App Store size limits. Acceptance tests: confirm video plays without black bars in App Store Connect preview, and that App Store does not reject for codec/frame-rate mismatch. If you use Play Store promo video, ensure it satisfies Play Console upload guidance.

Brief: “Deliver three static ad frames optimized for paid channels: portrait (9:16) for Stories/Reels, square (1:1) for feeds, and landscape (16:9) for YouTube/preview. Use the same visual language as store screenshots but tighter copy: 3–6 words headline, 6–12 words supporting line, and a visible CTA badge. Provide layered source and exports in PNG and JPG optimized for web.”

Test plan & acceptance: include a simple A/B test plan—swap headline or CTA across the three frames. Acceptance tests: check legibility at 320px width, CTA tap area visible, and file sizes under typical ad platform limits (keep JPGs below 150 KB where possible). Deliver alt text and suggested three ad copy variants for quick experiments.
