Make your app explain itself before it asks for registration.

Don't let registration be a barrier to exploring your app.
Many apps lose potential users because they're asked to create an account before they know what they're getting. No one likes being asked to enter personal information before they see a reason for it.
Offer an interactive, no-registration initial experience, such as browsing content or a limited trial of a service. Let the user discover what the app offers on their own.
Registration can be postponed until a need arises, such as saving results or customization, making it logical and easy to accept.
This way, the user feels confident and comfortable and builds an internal motivation to complete registration later.
Using barriers at the beginning of the experience reduces download and usage rates, while allowing free trials increases retention.

Why does explaining before registration increase engagement?
When you present the user with the option to register directly, they may hesitate or close the app because they don't yet understand its value. But when you start with a quick and clear explanation of the app, you build a bridge of trust between you and them.
Pre-explanation makes the user see that the app is designed to serve them, not just collect their data.
The clearer the app's benefit, the more likely they are to engage and register voluntarily.
Apps that explain themselves in a visual and interactive manner achieve higher conversion rates than those that force registration without introduction.
Provide value first, then ask for registration, not the other way around.

Steps to Designing a Stress-Free Experience
Start by defining the core objectives you want to communicate to the new user, such as: What is the app? How do they use it? What will they gain from it?
Design an interactive welcome interface, using a short video or simple animation to demonstrate how it works.
Rely on storytelling to explain: Start with a problem the user is experiencing, then show how the app solves it.
Don't ask for any data at the outset. Instead, offer a "Try it now without an account" option and make the basic experience as open-ended as possible.
Once the user begins interacting and feels useful, they'll feel that signing up becomes a natural step toward completing what they started.

The Difference Between a Hesitant and an Enthusiastic User
When you place registration at the beginning of the trial, you're dealing with a reluctant user who hasn't decided whether to continue.
But when you explain it to them first and invite them to try it, you turn hesitation into enthusiasm, and curiosity into commitment.
An enthusiastic user signs up willingly because they see real value. A hesitant user, on the other hand, might close the app after the first screen that asks for an email.
Change the trial entry from "Register Now" to "Try First," and see the difference in engagement.
Users don't like pressure; they like intelligent gradual progression.
