To start advertising your app on a basic level, you should create a website that offers more information about what it does, or what it provides. This will make your app searchable online

You can then set up search engine advertising, such as pay-per-click, which puts your ad in front of people who search for relevant terms, but only charges you if they click through to your website. You can also try incentivizing your existing users to spread the word to their friends, perhaps by providing discounted purchases for sharing your link, or providing a free in-app gift if they share your app via social media

The best way to get your app in front of lots of users, however, is probably with ASO. This essentially means optimizing your text and images in the app store so that when people perform a relevant search, your app will appear near the top

You should conduct some research to identify the most-effective keywords that will draw people to your app, and then use these in the title, description, and keywords sections

You should also make sure you have clear, high-quality screenshots of your app pages in your listing. These show visitors what it will be like to use your app—and they will be much more likely to download it as a result.
