Writing the code is rarely the slow part. The timeline of an app depends on scope, platform and the decisions made before the first line of code is written.
Timelines
There is no standard timeline that fits every app, but based on our projects these guidelines apply:
Those timelines apply to the build phase itself. What surrounds it — preparation, accounts, external parties — is a different story.
Biggest delay
Before an app appears in the App Store or Google Play, you as a client need a developer account with Apple and Google. With Google it is a matter of paying and waiting a few days. Apple works differently.
Apple wants to call before they activate an account. Scheduling that call, completing the verification and getting the account activated takes two to three weeks. If this is only arranged at the end of a project, a technically finished app sits waiting in the queue for weeks.
The solution is simple: arrange developer accounts on day one of the project, not when the app is ready.
Almost every business app communicates with something outside the app itself: a customer system, a planning tool or a payment platform. How smoothly that integration goes depends on the quality of external documentation and the availability of the other party. Integrations we have built before go considerably faster. For a new system, we build in time for alignment and testing.
Preparation
Many clients want to deliver the perfect product in one go. That is understandable, but it leads to a pattern we see regularly: preparation that never ends, because it can always be better.
A twenty-page functional design sounds thorough. But end users — the people who will use the app daily — look at a screen differently than the client expected. That is not a mistake, that is how software works. Not everything can be thought through in advance.
The result: the build starts months later than necessary, and part of the preparatory work turns out to need adjustment after the first user test anyway.
Our approach: start with what is clear enough now. Build it. Test it with real users. Adjust based on what you see. That cycle is faster and more reliable than trying to get everything right upfront.
Quality
No. And that is perhaps the most honest thing we can say.
We use automated tests, also known as unit tests. These tests automatically check whether a function still works after another developer has made changes. Writing those tests takes time during the build. But it saves considerably more time later: fewer bugs in production, faster further development, less rework.
An app that takes six weeks without tests is three weeks faster than a nine-week app with tests. But the app without tests pays those three weeks back later in extra bug fixes and delays with every update.
An app that does not work the way the end user expects is the worst starting point. Users who get a bad first impression rarely come back.
Arrange accounts early
Developer accounts with Apple and Google are day-one work, not a closing task. Apple requires a verification call that can take weeks.
Make decisions
A client who decides quickly and clearly prevents a project from waiting weeks for approval or direction.
Start small
A four-week MVP teaches more than a four-month full design. Build the smallest thing that is meaningful, test it, then expand.

Your timeline
The timeline depends on the conditions outside the code: accounts, integrations, decision-making. Those who arrange these things early lose no time waiting.
