A great user onboarding flow aims to provide new users with a seamless and engaging experience as they start using a product or service. An effective onboarding flow should guide users through the key features, help them understand the value proposition, and encourage them to become active and engaged users. Here's an example of a great user onboarding flow for a mobile app such as https://depthcrypto.com Upon opening the app for the first time, users are greeted with a welcoming message and a brief description of the app's purpose - tracking fitness activities and goals. The app prompts users to create an account or log in. During this step, users can provide their fitness goals, preferred workout types, and basic information to personalize their experience.

Slack's onboarding flow stands out. They walk you through the entire process with tooltips, visuals, and prompts, making sure you understand the platform.
