Design an app icon that stands out on the home screen
Pick a mark, colours and background, preview it at real size on a home screen and download the 1024 × 1024 master PNG Apple requires, then use the guide below to make it unforgettable.
How to use the app icon maker
Choose a letter or one of the built-in glyphs, pick a colour palette and a background style, and toggle the soft highlight. The preview updates instantly, and the home screen below shows your icon at real size next to other apps, which is the view that matters most. When you are happy, download the 1024 by 1024 PNG.
The file is a full square with no transparency. That is deliberate: App Store Connect rejects icons with an alpha channel, and Apple applies the rounded mask itself. Upload the PNG to your Xcode asset catalogue or App Store Connect, or keep it as a starting point for a designer.

Apple's icon requirements in one table
| Requirement | Detail |
|---|---|
| App Store size | 1024 × 1024 pixels |
| Format | PNG, no transparency or alpha channel |
| Shape | Square; iOS applies the rounded mask |
| Colour space | sRGB or Display P3 |
| Variants | Light, dark and tinted appearances recommended on recent iOS versions |
| Content | No screenshots of the UI, no Apple hardware images, no misleading imagery |
These requirements come from Apple's Human Interface Guidelines for app icons and App Store Connect. Check both before you upload, as Apple updates them from time to time.
Principles of a great app icon
One focal point. The best icons have a single, simple shape that can be recognised in a fraction of a second. If you need to explain the icon, it is too complex.
Bold at every size. Your icon appears at 1024 pixels on the store and at about 40 pixels in Settings and Spotlight. Fine lines and small details disappear. Test it small.
Distinct colour. Look at the top apps in your category. If every competitor is blue, a warm colour will stand out. Our top charts page is a good place to study category colours.
No words. The app name already appears under the icon. Text in the icon competes with it and becomes unreadable.
Consistent with the brand. The icon, the app's primary colour and the first screenshot should feel like one family.
A simple process designers use
- Write the idea in one word. Speed, calm, money, growth, safety. That word guides the shape.
- Sketch ten tiny versions. Draw them at thumbnail size first. Anything that does not work small is discarded early.
- Pick three and build them properly. Use a grid, consistent stroke weights and a limited palette.
- Test on a real home screen. Put each version next to popular apps and look from arm's length.
- Check every appearance. Light, dark and tinted modes, the App Store, notifications and Settings.
- Choose and refine. Small adjustments to contrast and proportions make a big difference at small sizes.

Colour, contrast and depth
Colour is the fastest signal on a crowded home screen. Use a strong background colour or gradient and a contrasting mark. Subtle gradients add depth without clutter; a gentle highlight at the top, like the one in this tool, mimics the soft lighting of many system icons.
Check contrast between the mark and the background, especially for users with low vision. If your brand colour is light, use a dark mark, and vice versa. For dark mode, many icons switch to a darker background with a brighter mark; the tinted mode uses a single tone, so the shape must work without colour.
Common icon mistakes
Using a photo or a screenshot. Photos rarely read at small sizes, and screenshots of your interface look cluttered.
Too many elements. A phone, a chart, a coin and a star is four ideas. Pick one.
Thin outlines. Hairline strokes vanish at small sizes.
Copying a famous icon. Similar shapes and colours to a well-known app confuse users and can lead to App Review problems under Apple's intellectual property guidelines.
Rounding corners yourself. iOS applies the mask; pre-rounded corners create odd double curves.
Icons by category
Finance. Calm, trustworthy colours such as deep green, navy or black with a simple geometric mark.
Health and fitness. Energetic colours, a single motion-based shape such as a ring, wave or flame.
Productivity. Clean, bright icons with a crisp symbol, such as a check, a spark or a folded shape.
Games. More illustrative icons are common, often featuring a character or object, but they still need a clear silhouette.
Social and creator apps. Bold gradients and friendly shapes that feel human.
Testing icons on the App Store
Your icon affects how many people tap your app in search results and charts. Apple lets you test alternate icons as part of product page optimisation, alongside screenshots and preview videos, as described in Apple's product page guidance. Run one test at a time and give it enough traffic to reach a clear result.
From icon to a complete store page
Once your icon is ready, create screenshots that use the same colours with the free screenshot generator, name your app with the app name generator and tidy your metadata with the ASO keyword tool. The App Store Studio brings all of it together for submission.
Let Muaz.io design the icon with the app
When you build with Muaz.io, the Design Engine creates an icon from your brand tokens alongside the app's interface, with light, dark and tinted variants and a check at every size. Paste your website or describe your idea in the builder above to see it on a live iPhone home screen.
Designing alternate icons
Many apps let users choose an alternate icon, for example a dark version, a seasonal design or a reward for loyal subscribers. iOS supports alternate icons that the app can switch to with the user's permission. They are a delightful touch for premium tiers and community-driven apps, and they give your design team a fun way to celebrate milestones. Keep alternates recognisably part of the same family so users never wonder which app they are looking at.
Accessibility considerations
An icon is often the first thing a person with low vision has to recognise. High contrast between the mark and the background, a simple silhouette and avoiding colour as the only differentiator all help. Remember that some users enable larger icons or zoom, and that the tinted appearance removes colour entirely, so the shape alone must carry the identity. Test your icon in greyscale as a quick check.
Working with a designer
If you hire a designer, give them a clear brief: the one word your icon should express, your brand colours, three competitor icons you want to stand apart from and the contexts where the icon will appear. Ask for options at thumbnail size before polished versions. Request the master file in a vector format, the 1024-pixel PNG without alpha and the dark and tinted variants. The icon you create with this tool makes a useful starting reference for that brief.
How often should you update your icon?
Most successful apps change their icon rarely, because recognition builds over time. Small refinements, such as updated colours or simplified shapes, are common every few years. Seasonal or event icons can work for games and entertainment apps when they are temporary. If you do change your icon significantly, update your screenshots and marketing at the same time, and tell users in the release notes so they can find the app on their home screen.
Icon size reference for iOS
Although you only upload one 1024-pixel master, it helps to know where your icon appears. On the home screen it appears at around 60 points, which is 180 pixels on high-resolution displays. In Spotlight and Settings it appears smaller, around 40 and 29 points. In notifications it appears as a small badge next to the message. Your design must work at all of these sizes, which is why the home screen preview in this tool is so important. Xcode can generate the device sizes from the master image when you use a single-size asset in your asset catalogue.
Checklist before upload
Before you upload, confirm a few last details. The image is exactly 1024 by 1024 pixels. It has no transparency and no pre-rounded corners. The mark is centred with comfortable margins so the mask does not clip it. The icon reads clearly at thumbnail size. It looks good in light, dark and tinted modes. It does not resemble another app's icon or use anyone else's trademark. And it matches the colours and feel of your screenshots and app interface.
The anatomy of an icon
Most great icons are built from three layers. The background sets the colour and mood, usually a solid colour or a gentle gradient. The mark is the single shape that carries the identity, such as a letter, a symbol or a simple object. The light adds depth: a soft highlight at the top, a subtle shadow under the mark or a gentle glow. Keeping these layers separate in your design file makes it easy to produce the dark and tinted variants Apple recommends, because you can change the background and light while keeping the mark consistent.
Grids and proportions
Apple's design resources include icon templates with a grid of circles and squares that help you balance shapes. A mark that fills roughly 60 to 70 percent of the icon's width usually feels confident without touching the edges. Circular marks often need to be slightly larger than square ones to look the same size, because circles appear smaller to the eye. Keep a comfortable margin from the edges so the rounded mask never clips important details. The icon maker on this page centres and sizes marks with these proportions by default.
Choosing colours that work
Start from your brand's primary colour, then check how it looks on a busy home screen next to popular apps. Saturated, mid-to-dark colours tend to stand out; very pale colours can disappear against light wallpapers. Two-colour gradients add richness, but keep the hues close enough that the icon feels like one object. Check contrast between the mark and background with a simple test: convert the icon to greyscale and make sure the mark is still clearly visible. That also tells you how the tinted appearance will look.
Letters as marks
A single letter can be a strong icon when the letterform is bold and the colour distinctive. Choose a typeface with character, consider customising the letter so it becomes unique, and make sure the letter is centred optically, not just mathematically; letters such as "A" and "V" often need small adjustments. Two-letter marks can work for short brand names, but three or more letters usually become too small to read. If your app name starts with a common letter, add a distinctive shape or colour so it does not look like a dozen other apps.
Symbols and metaphors
Symbol icons communicate what the app does at a glance: a flame for streaks, a leaf for wellness, a bolt for speed, a ring for progress. The best symbols are simple enough to draw from memory. Avoid literal objects that many apps already use, such as a generic camera or a chat bubble, unless you give them a distinctive twist. Test whether people can guess the app's purpose from the symbol alone; if they can, the icon is working.
Icons for different categories, revisited
Category conventions help users scan, but following them too closely makes you blend in. Study the top apps in your category on our top charts page, note the dominant colours and shapes, then deliberately choose one dimension in which to differ. If most competitors use blue symbols on white, a white symbol on a warm colour will stand out. If most use realistic illustrations, a flat, bold mark will look fresh. Differentiation in the icon is one of the cheapest ways to improve your conversion in search results.
Testing your icon with real users
Before you finalise, run a quick test. Put three icon options on a home screen mock-up among popular apps and show it to people for three seconds, then ask which icon they remember and what they think the app does. Repeat with a search results mock-up that includes competitors. The icon people remember and understand is usually the right choice, even if it is not the one you liked best.
Exporting and handing off
When your icon is final, keep a master file in a vector format so you can produce any size later. Export the 1024-pixel PNG without transparency for App Store Connect, plus dark and tinted variants if you provide them. In Xcode, add the icon to your asset catalogue as a single-size asset, and Xcode generates the device sizes. If you build with Muaz.io, the Publishing Agent adds the icon to the project and App Store Connect automatically, and checks it against Apple's requirements before you submit.
Glossary of icon terms
Master icon. The 1024 by 1024 pixel image you upload to App Store Connect.
Alpha channel. Transparency information in an image; App Store icons must not have one.
Mask. The rounded-square shape iOS applies to every icon automatically.
Tinted appearance. A home screen mode where icons are shown in a single tone chosen by the user.
Alternate icon. An extra icon users can switch to from inside the app.

Download your icon from the maker above, then create matching screenshots and a name that fits it. When you are ready to build the whole app, paste your website or idea into the builder at the top of this page.
Icon mistakes we see most often
After reviewing many first-time icons, the same issues come up again and again. The mark is too small, leaving a large empty background that makes the icon look unfinished. The colours are too close in brightness, so the mark disappears at small sizes. The design includes a thin border, which looks like a mistake once the system mask is applied. The icon uses a stock symbol that dozens of other apps also use. Or the icon is beautiful at 1024 pixels but becomes a muddy blur on the home screen. The fix in almost every case is the same: simplify, enlarge the mark, increase contrast and test small.
How icons affect conversion
In App Store search results, your icon sits next to your competitors' icons for the same query. People make a split-second judgement about quality and relevance, and the icon is a large part of it, along with the name, rating and first screenshots. A clear, distinctive icon signals a well-made app. That is why many teams treat the icon as a growth asset and test variations once they have enough traffic, using Apple's product page optimisation tools. Even small improvements in the share of people who tap your app add up over thousands of impressions.
Icons and brand consistency
Your icon is the most visible part of your brand on a phone, so it should match the rest of your identity: the same primary colour as your app's buttons and headers, a mark that echoes your logo and a style consistent with your screenshots and website. When these elements match, users recognise your app instantly in notifications, search results and the home screen, and the experience feels coherent from the first tap.
Icon checklist for teams
If several people are involved in choosing the icon, agree on the criteria before you look at options: the one word it should express, the colours it must use, the competitors it must stand apart from and the sizes where it must work. Review options at thumbnail size first, in a home screen mock-up, then at full size. Decide with a short vote after the tests, not before, and record why the winning icon was chosen. That record is useful when someone suggests a redesign a year later.
Why this tool exports a full square
Some icon tools export pre-rounded PNGs with transparent corners, which App Store Connect will reject. This maker always exports a full, opaque square at 1024 pixels, which is exactly what Apple asks for. Upload it as is, and let iOS handle the rest.

Questions about app icon maker
Short, direct answers. Still curious? Ask in the builder; the assistant knows your project.
What size should an iOS app icon be?
App Store Connect requires a 1024 by 1024 pixel icon for the App Store. Xcode can generate the smaller sizes used on the device from this single master image.
Can an app icon have a transparent background?
No. The App Store icon must be a square image with no transparency or alpha channel. Apple applies the rounded corner mask automatically, so you should not round the corners yourself.
Should I put text in my app icon?
Generally no. Text becomes unreadable at small sizes and the app name already appears under the icon. A single letter or simple symbol can work if it is bold and clear.
Does the icon affect downloads?
Yes. The icon appears in search results, top charts, the home screen and notifications. A clear, distinctive icon helps people recognise and choose your app, and many teams test icon variations on their product page.
Do I need dark and tinted icon variants?
Recent versions of iOS let users choose dark and tinted home screen appearances. Apple recommends providing variants so your icon looks right in each. Muaz.io can generate them from your master design.
Is the icon I make here mine to use?
Yes. The icon is generated on your device from shapes and letters you choose. Avoid using other brands' logos or trademarks in your design.
