Your answer -:

Show a message only once (onboarding example)

When your user first downloads your app it’s quite common to show them some sort of welcome message, or some instructions about how to use your app. This is a great idea for someone who has just installed your app, but for someone that opens your app regularly this can become repetitive and annoying. In this tutorial, we’ll look how you can use stored variables to show an onboarding message the first time a user opens your app, but hide if from them every time they subsequently open your app. …

This will probably solve your problem

Good Luck!
