Users around the world installed around 120 billion mobile apps in 2019. According to forecasts, the use of mobile applications will generate $189 billion in revenue in 2020. Isn't that impressive? Let's continue: The average mobile device owner uses about 30 programs every month. He/she selects and installs them from 2.8 million applications for Android or 2.2 million applications for iOS. Do you know which criteria the user uses to make a selection?
What does a mobile application need an icon for?
The icon of a mobile application helps to find a specific program among the hundreds of thousands of offers from the competition. It's the first thing a user sees when browsing a store or searching for a specific program. If you make the icon compelling, then it will help get the app installed more often. However, a poor quality icon does exactly the opposite: it raises doubts and repels potential customers.
The application icon is a unique image that, along with the original name, is a mandatory part of the program. If the program is already installed, then the icon has a different purpose. Then it serves to recognize the program among others on the device. A good symbol adequately fulfills all functions. Let's find out what is considered a good picture.
6 tips for creating an effective icon for mobile applications
1. General Requirements
An important rule: create an icon based on official recommendations from developers of mobile operating systems. There are open Apple guidelines and tips for designers of Android products. Development should take into account these standards and the requirements listed below.

2. Scalability
The mobile application icon is displayed on the shop page and it can be seen in a smaller version in the submenu. When the program is installed, it will be displayed in the smartphone menu. The image size will be different in each case. This depends on many factors, including screen resolution and settings . The image creator should ensure that the recognition value and the details are retained with all display options. You can check this factor using the Appsparky service.

3. Uniqueness
Originality is an important requirement for a mobile application icon. Copyright infringement will cause problems. Uniqueness is also a necessary attribute when competing for user attention. Try the following to get a unique application icon:
- Analyze the logos of applications in your niche. This is necessary in order not to repeat the ideas of other designers.
- Experiment, break boundaries and find new symbol and color combinations.
- Use your own identity: Rethink it or use it.
Here is an example of adopting another identity. The images may look unique, but they still resemble the original. The first picture shows the icons of MS Office programs:

The second picture shows similar programs from LibreOffice:

4. Detectability
Users should understand everything presented on a mobile application icon without further explanation. Nothing should be an obstacle, neither the language a person speaks nor the country in which they live. The easier the symbol is to understand, the more effective it is. The YouTube logo in the form of a stylized play button is easily recognized by most users:

5. Minimum of letters
You can use letters and abbreviations in your own program logo if your brand identity has been developed over a long period of time and is familiar and recognizable to people. For example, people recognize the letter "f" as a Facebook symbol at first glance. If brand imagery isn't that developed yet, then you should look for another option.
Designers advise omitting the words in the symbols altogether. General Opinion: If visual elements need to be complemented by letters, then they have not been developed well. A few more reasons not to use letters in the picture:
- The name of the program is displayed next to the icon.
- Letters distract from visual elements.
- It is difficult for the user to focus on one thing.
- You have to reduce the visuals because of the letters. This reduces the recognition value.
An exception is when the brand's logo consists of letters and they are written in a distinctive, recognizable style. This is what the developers of Biugo did, for example (the icon for their video editing program Noizz can be seen in the example):

6. Logo and functionality as a whole
The user should perceive the icon and the interface of the mobile application equally. The appropriate icon is part of the overall concept of the software, its holistic image and ideas. The requirements are therefore:
- Matching the style and color scheme of the interface.
- Good visibility on different types of background images and with light or dark themes or shop designs.
The IconTester service gives you the opportunity to check how the icon looks on different background options.

The trends of modern application icons
Design requirements change annually. The user interface comes first: optimization of the external elements for customer satisfaction. How does this affect the app icon? After analyzing the trends for 2020, we give the following recommendations for image development:
- Maximum importance. As few unimportant elements as possible. Every detail of the picture should have a meaning. For example the picture of Ablo. The paper plane symbolizes the transmission of messages and the graphic element below indicates the high speed of communication:

- three-dimensional images. Such icons are more informative and detailed. They simplify the transfer of information to the user. This trend is often used by mobile game developers (e.g. Call of Duty: Mobile). The detailed three-dimensional figure in the middle draws attention:

- gradients. This is one of the most important trends that will continue in 2020. The simple use of gradients makes the icon design look more vibrant. Here is the solution for the Specter Camera app (an icon representing a camera lens, with subtle color gradients):

- Empty room. Minimalism has been driving design trends for a number of years and empty space is a natural part of it. He focuses on the main element of the symbol. Microsoft Edge is an example of this (an element symbolizing the browser on a plain white background):

How to develop an icon for an Android app
The application icon for Android apps has to be developed considering the screen resolutions and the current settings of the device. Android uses the DPI value to measure graphics quality, which is the number of dots per inch (dots per inch). A distinction can be made between the following values:
- LDPI (120)
- MDPI (160)
- HDPI (240)
- XHDPI (320)
- XXHDPI (480)
Installed application icon requirements
The image for launching the program must be created in PNG format (32-bit), on a transparent background. The level of detail depends on the DPI value. The minimum value for MDPI is 48dp, with a margin of 1dp. For other indicators, the following values are relevant (in pixels):

The standards for icons to upload to Google Play
The icon size for the mobile program is 512×512 pixels with high resolution. The icon displayed in Google Play has a different size than the icon used for the installed application. More recommendations:
- Format: PNG, 32-bit.
- Maximum size: 1024 KB.
- Color space: sRGB.
- Square shape with no rounded corners (the system rounds them, with a radius of 20 degrees).
- No shadows: the system will generate them automatically.
Recommendations for development
How to create an icon for an Android app? Here are a few tips:
- Place all important elements in the middle. Make sure the empty space is closer to the edges and in the bottom third of the frame.
- Do you use the logo? Place it right in the middle.
- When using letters and words (if necessary), choose a large, legible font.
- Make sure it is recognizable at any size and suitable for different backgrounds.
It is important that the Android app icon helps to solve a specific problem. For example, an icon with corporate symbols makes branding easier. An image with an original, attractive design will attract users.
How to create an icon for an iOS app?
The iPhone application icon needs to be developed in two versions: small and large. The first is displayed after installation (in the system and on the main screen). The second is for the Apple Store. This table contains all icon size recommendations:

You will need to develop several small icons for different iOS devices . Of course, the difference should only be in size, that is, there should be no visual differences. The main requirements for the symbols are:
- Size: 1024×1024 pixels.
- 72 dpi, in one layer, with no transparent background.
- Formats: PNG or JPEG.
Don't add a frame to the icon. This is done automatically in the form of a 1-pixel indent.
iOS app icon standards
Here are a few rules:
- Minimalism in design. A central graphic element (main element) on a neutral background, without unnecessary details, is sufficient.
- focus of attention. We need an element that draws users' attention and makes clear the purpose of the application.
- detectability. The user does not have time to solve puzzles, that is, the meaning of the icon should be clear.
- Only images for which you own the copyright. It is forbidden to use the attributes of other brands.
- The compatibility of the application icon with different color options for custom wallpapers.
- Right angles (they are automatically rounded).
- Considering the features of dark mode introduced in iOS 13. See The Mac Observer for an example of an image on a dark background.
