Alight Motion is a popular video editing and animation app, and it is available for download on official app stores like Google Play Store (for Android) and the App Store (for iOS). To access the Pro version of the app, you will typically need to purchase a subscription or make an in-app purchase through the official app store.

I encourage you to support the developers by downloading the app from the authorized sources to ensure you have a legitimate and secure version. Downloading cracked or unauthorized versions of apps may violate copyright laws and terms of service, and it can also expose your device to security risks.
