## What it is
ProductTour is an Android sample project implementing a parallax-effect welcome/onboarding screen using ViewPager and PageTransformer, mimicking intro pages in Google apps like Drive and Docs. It supports tablets and Android API 9+ and is written in Java.

## Use cases

## When to choose
- you need a Google-style parallax onboarding/intro screen on Android

- you must support very old Android versions (API 9+)

## When to avoid

- you want a full-featured intro framework with many customization options
- your project is Kotlin-first and you prefer idiomatic Kotlin libraries
