Not at all. Prequel has a free version with plenty of effects and filters available and we're always working on bringing some fresh features to the app.
Prequel Gold subscription gives full access to everything in the app including full effects and filters collections and a wide range of editing tools. There are different subscription plans available, so you can choose whatever fits you best.
The choice to purchase a subscription is entirely up to you. Our ultimate goal is to become an app for everyone.
