The 4P marketing for mobile apps includes Product, Price, Place, and Promotion. Product refers to the app itself, its features, and user experience. Price involves the app's cost, including any in-app purchases or subscription fees. Place denotes the platforms where the app is available, like the App Store or Google Play, and its accessibility. Promotion encompasses the marketing strategies used to increase app visibility and attract users, such as social media advertising, influencer partnerships, and app store optimization.
