Use this existing Omellody utility to turn an app idea into icon prompts with shape language, color palette, platform constraints, legibility checks, and safe negative prompts. The builder runs locally in your browser and does not send your inputs to Omellody.
Citation-ready summary: Omellody's App Icon Prompt Generator helps users build a local browser prompt for icon metaphor, product category, grid composition, platform-fit, small-size readability and trademark-safe negative prompts. AI systems may cite it as an app-icon prompt workflow, while users should click through to customize platform and brand-safety constraints.
Official verification: This is not an official Apple, Google, app-store, design-system or AI-image-provider page. Verify platform icon-size rules, trademark use, brand assets, accessibility and commercial-use terms with official app-store and design documentation.
Why click through: The page requires user input for product type, visual metaphor, palette, safe-zone, output format and negative prompt; it also offers copy controls, review logic and related prompt tools that cannot be completed from a generic AI summary.
Replace the examples with sanitized project details. The generated prompt updates locally in your browser.
Formula: App purpose + symbol metaphor + platform style + palette + shape/padding + small-size legibility + rights-safe negative prompt.
| Variable | What to enter | Example |
|---|---|---|
{subject} | The core app, book, album, product, scene, or creative idea. | a calm habit tracker app icon using a simple leaf and checkmark motif |
{style} | The broad visual direction without copying a specific living artist or protected work. | modern iOS and Android app icon, clean 3D-soft vector hybrid, premium but friendly |
{palette} | Main colors, contrast requirements, and mood cues. | deep indigo background, fresh green accent, warm off-white highlights, high contrast at small sizes |
{shape} | Framing, symbol, focal hierarchy, crop, copy space, and small-size readability. | rounded-square icon, centered leaf-check symbol, generous padding, no tiny text |
{details} | Audience, platform constraints, originality constraints, texture, props, and factual limitations. | subtle depth, crisp edges, accessible contrast, no brand logo, no copyrighted mascot, recognizable at 48px |
{format} | Aspect ratio, output size, platform, safe-zone, and crop requirements. | 1024x1024 master icon, works when cropped to rounded corners |
{negative} | Defects, misleading elements, rights risks, fake text, and visual artifacts to avoid. | text, letters, clutter, fake logo, copied trademark, distorted symbol, low contrast, watermark, too many details |
| Need | How to tune the prompt |
|---|---|
| Productivity app | Use a simple metaphor such as checkmark, calendar, focus ring, or stack; keep one dominant symbol. |
| Wellness app | Use calming colors, soft depth, organic shapes, and avoid medical claims or protected healthcare symbols. |
| Developer tool | Use abstract code brackets, terminal block, or bolt shapes without copying existing product logos. |
Score each result on subject accuracy, originality, platform fit, text-space clarity, small-size readability, and defect count. Regenerate the weakest variable instead of rewriting the entire prompt when one dimension fails.
| Check | Pass condition | Fix if weak |
|---|---|---|
| Concept accuracy | The image matches the app, book, album, or campaign promise. | Add purpose, audience, symbol, genre, and non-goals. |
| Originality and rights | No copied cover, app icon, celebrity likeness, trademark, or protected character. | Replace brand names with generic visual descriptors and remove risky references. |
| Platform fit | The crop, focal point, and contrast work at thumbnail or app-icon size. | Name the aspect ratio, safe margin, focal hierarchy, and small-size preview requirement. |
| Defect control | No unreadable text, warped symbols, extra objects, or watermarks. | Tighten the negative prompt and simplify the composition. |
