To assist you understand the cost involved in establishing an on-demand beauty service app, below is a full breakdown of each component:

Features and Functionality: The features and functionality you wish to incorporate will have the biggest impact on the cost of app development. User registration, service selection, booking, payment processing, scheduling, and notifications are examples of basic functionalities.

Platform (iOS, Android, Web): The cost of development is greatly influenced by the platform selection. It will be more expensive to create separate apps for the iOS and Android platforms than it will be to create a single cross-platform app with React Native or Flutter as the framework.The total cost of development will go up if you decide to create both a mobile and online version of the app. 

Design: The user experience is improved by well-designed software with an easy-to-use interface and eye-catching graphics, but the cost of development goes up. Using pre-designed templates or themes will save money compared to custom UI/UX design that is targeted to your target demographic and brand identity. 

Development Team: The cost is affected by the makeup of the development team, which consists of project managers, designers, front-end and back-end developers, QA testers, and maybe experts in AI, AR, or other technologies.

Project Management: Activities like requirement analysis, project planning, coordination, communication, and quality assurance are all included in the cost of project management. The total cost of development increases with the use of project management tools or the hiring of a dedicated project manager.

Testing and Quality Assurance: The app must be tested and put through quality assurance procedures to make sure it works properly and is error-free. Although it raises the cost of development, allocating enough time and resources for testing—both automated and manual—ensures a high-quality final result.

Launch and Maintenance: There are extra charges for app store fees and submission when the app is launched on app shops (Google Play Store, Apple App Store, etc.). Continuous investment is needed for post-launch maintenance and support, which includes bug repairs, upgrades, feature enhancements, and server maintenance.
