Process

How we take your project from idea to launch

  1. Week 1

    Discovery & scoping

    Workshops with your stakeholders to map users, goals, constraints and the smallest release that proves value.

  2. Weeks 2–3

    UX & architecture

    Clickable prototypes, data models and a system design document you sign off before a line of production code.

  3. Ongoing

    Agile build sprints

    Two-week sprints with a demo at the end of each one, a shared board and a staging link that always works.

  4. Every sprint

    QA & security

    Automated tests, manual regression, performance budgets and an OWASP-aligned review before every release.

  5. Go-live

    Launch

    Store submissions, cloud setup, monitoring and a rollback plan — launches happen on a checklist, not on hope.

  6. Post-launch

    Support & growth

    SLA-backed maintenance, analytics reviews and a roadmap for the next release once real users arrive.

FAQ

iOS App Development FAQs

Straight answers to the questions we hear most. Can't find yours? Email us and a senior team member will reply.

Ask a question
How long does it take to build an iOS app?
A focused first version usually takes 10–16 weeks including design, development, testing and App Store submission.
Will my app pass App Store review?
We design and build with Apple's guidelines in mind and prepare all privacy and review information upfront, which keeps rejections rare and quick to resolve.
Can you also build the Android version later?
Yes. We can build a native Android app later, or recommend a cross-platform approach from the start if both platforms are planned.
How much does a software project cost?
It depends on scope, platforms and integrations. After a short discovery call we share a written estimate with a feature-by-feature breakdown, so you can choose what goes into the first release and what waits.
Will I own the source code and IP?
Yes. All source code, designs and intellectual property are assigned to you under our agreement. We sign an NDA before discussing your idea in detail.
How do you communicate during the project?
You get a dedicated project manager, a shared task board, a weekly written report and a sprint demo every two weeks. Slack, Teams, Google Meet or Zoom — whatever your team already uses.
