The Mobile App Development Process, From Idea to Launch

Discovery (three to five days): before any screen is designed, the goal is agreeing in writing on what the app needs to do, who's using it, and what "done" looks like for a first version — plus naming the parts that are genuinely uncertain, like a payment integration nobody's tested yet.

Design (five to seven days): flows and wireframes turn the written scope into something you can react to, followed by real UI screens and a clickable prototype you can test on an actual phone before any production code exists.

Development (two to four weeks, depending on scope): built in weekly cycles with a demo every week — often on a real device or an internal test build — so you're never seeing the app for the first time on delivery day.

Launch (a few days): a release checklist, App Store and Google Play submission, and a real handover — documentation, credentials, and a walkthrough — because a demo isn't the same thing as your team being able to run and extend the app afterward.

Store review is worth planning for separately: Apple and Google both review submissions before an app goes live, which is why the release checklist starts before development technically "ends," not after.
