Planning
The team first defines the users, screens, features, and information the app needs.
Unclear requirements often lead to changes during development, which can increase the timeline.
Design and development
The app screens and supporting system are designed and built.
An app may also need an admin panel, database, notifications, payments, or connections with other services.
Testing
Testing checks common devices, screen sizes, user actions, and error cases.
Problems found during testing need time to fix and test again.
Launch preparation
Android and iPhone stores have their own submission requirements. Store information, screenshots, privacy details, and account access should be ready before submission.
Get a clearer timeline
Write down the main user, the main task, and the features needed for the first release. A development company can then prepare a more useful estimate.
Approved timelines for small, medium, and larger apps still need to be added before this article is published.
