Most people underestimate how long a quality app takes, then rush the parts that matter. A realistic timeline depends on scope, but knowing the phases and typical durations will help you plan a launch and hold your development partner accountable.
Typical timelines
- A focused MVP: about 2 to 4 months from kickoff to launch.
- A standard app with custom features: about 4 to 9 months.
- A complex platform or marketplace: 9 to 12 months or more.
These assume a dedicated team and reasonably prompt decisions on your side. Timelines stretch quickly when scope grows mid-project or feedback is slow.
The phases of a build
- Discovery and planning (1 to 3 weeks): defining scope, users, and requirements.
- Design (2 to 6 weeks): wireframes, UI design, and a clickable prototype.
- Development (2 to 6 months): building the app and backend in iterative sprints.
- Testing and QA (ongoing, plus 2 to 4 weeks before launch): finding and fixing issues across devices.
- Launch (1 to 2 weeks): app store submission and review, which Apple and Google control.
What speeds it up or slows it down
The fastest projects have a tight, well-defined scope, a single decision-maker who responds quickly, and a team that has built something similar before. The slowest have shifting requirements, slow feedback, and features added after work has started. If speed matters, cut scope rather than cutting corners on testing, and launch a smaller first version you can build on.
