アプリ公開に集中するためのワークフロー
プロダクト画面からストア提出用素材へ
These tools cover screenshots, platform-specific sizes, and listing icons. Use the composer when captures still need marketing layout; use the resizer when artwork is finished and needs exact presets; use the icon generator when you already have a logo and need multi-size PNGs.

このワークフローの位置づけ
DevCove focuses on deterministic, browser-local export—not a full design suite or AI asset generation.
- Photoshop / Figma — maximum creative control; you manage every store size and policy check manually.
- Canva / AppMockUp — fast templates; assets often live in the cloud and may need a subscription.
- Generic image cropper — everyday ratios; no App Store / Google Play presets or upload checklist.
- DevCove app store tools — compose, resize, and icon export with official presets, policy hints, and local processing.
アップロード前に確認
- Screenshots show real in-app UI for the build you submit.
- Google Play PNGs and JPEGs use opaque backgrounds where required.
- Feature graphic is a separate 1024×500 asset—not a cropped phone screenshot.
- Icons are square PNGs without pre-rounded corners on iOS.
- First two or three screenshots communicate the core value quickly.
