App Clips on the App Store and Instant Apps on Google Play Store are preview versions of native apps. They are similar to food samples at a market. Before deciding if you want to buy the delicious-looking cheese, you can try it to make sure you like it.^[[1]]

With app previews, the idea is that users can try out apps without downloading them. These light app versions are beneficial to both the user and developers. Users don't need to commit, and developers can learn about users' habits immediately after releasing their product.

Preview apps can be started from links in search results, social media shares, messages, beacons, or NFC. One app can have previews of several features. For example, creating separate previews for single-player and multiplayer modes of the same game. Preview apps aren't difficult to develop as they use the existing code. They can really improve your retention rates as only interested users end up downloading and keeping the actual app.
