How to improve D1 retention?

To improve D1 retention (user retention on the day after installation), it is important to focus on the first user experience and motivation to return:

• Provide a quick and clear onboarding so that the user immediately understands the value of the product.
• Offer useful and relevant content or features immediately after launch.
• Use push notifications or emails with personalized messages reminding about the product.
• Minimize bugs and technical issues that could scare off new users.
• Implement gamification or other engagement mechanics that encourage repeated use.

For example, in a mobile app, you can show a welcome tutorial and immediately suggest performing the first useful action, and the next day send a notification with a useful tip or promotion.
