Hosting costs depend on the app's user base and the type of app (e.g., e-commerce, streaming, or gaming).
Regular updates are crucial to maintain compatibility with new OS versions (iOS, Android) and devices.
Many apps rely on third-party APIs (e.g., payment gateways, map services) with recurring subscription fees.
Ensuring data security and compliance with regulations (e.g., GDPR, CCPA) is vital.
Offering 24/7 customer support and app monitoring to handle issues or crashes adds to the cost.
