Examples to make your own
Your idea
A focus timer app represented by one orange hourglass on dark navy.
A more useful prompt
Square app icon concept with one bold orange hourglass on a solid dark navy background. Use clean flat filled shapes, generous inset padding and strong silhouette contrast. No text, device frame, baked rounded corners or external shadow. Test small previews and platform masks before exporting.
Your idea
A reading tracker using a mint bookmark symbol on deep purple.
A more useful prompt
One mint bookmark symbol centered on a solid deep purple square. Use a flat filled shape with generous safe space and a silhouette that stays clear at small size. Do not add book titles, progress numbers or badges. Keep the base artwork square and prepare masked previews and platform exports separately.
Plan the visual
Focus on one recognizable symbol that represents a real app function. Use a short palette and strong contrast rather than tiny lettering, screenshots or a collection of feature illustrations.
Prepare the final artwork
The output is an artwork brief, not a platform export package. Test the result at small sizes and under different masks, then prepare the separate assets required by your target platform.
