The time taken to develop an app absolutely depends on its complexity. Outlining the scope of the app, including its features and functions, would range between 1–2 weeks for small apps and 2-4 weeks for larger ones. UI and development usually take 2-3 weeks for simple apps and around 8-10 weeks for complex, extensive apps. This is followed by alpha testing and beta testing to uncover faults. On average, a simple app may take 2–3 months while extensive ones might take 4-6 months to be developed.
