Mobile App Development, Explained
How We Build an App
- Research: interviews and tests with the people who will use it, and the data you already have.
- Design: flows, prototypes and the UI, tested with users while changes are cheap.
- Build: iOS and Android, with the back office and integrations the app needs.
- Test: usability tests on the key flows before launch.
- Launch and improve: analytics from day one, then releases based on what users do.

What Drives the Cost
The number of features and screens, iOS, Android or both, the integrations and back office, how much research and testing you want, and support after launch. We scope each app after a short call.
Redesign or New App?
Many projects start with an existing app. A usability test of the current version shows what to keep, what to fix and what to rebuild, so the budget goes where users feel it.

KAIFrequently Asked Questions
How much does it cost to build an app in Indonesia?
It depends on the features and screens, the platforms, integrations and back office, research and testing, and support after launch. We scope each app after a short call.
Do you build for iOS and Android?
Yes, for both, and the web tools that go with the app.
Can you redesign our existing app?
Yes. We usually start with a usability test of the current app, so the redesign fixes what really bothers users.
Do you do the design and the development?
Yes. Research, UX/UI design and development are done by one team, so what is tested is what ships.
Can you work with our developers?
Yes. We can design and hand over with specs and design QA, or build together with your team.
Do you test the app with users?
Yes. Key flows are tested with real users before launch, and again after major releases.
Do you support the app after launch?
Yes. We can stay on to improve the app based on analytics and user feedback.
How long does it take to build an app?
It depends on the scope. We plan it after a short call and release in stages so you see progress early.
