Our work process — from brief to App Store
Brainstorming & Requirement Analysis
We define v1 jobs, iPhone vs iPad, digital-goods rules and whether native iOS is the right bet.
Prototyping & Mockups
HIG-led flows, privacy prompts and clickable prototypes before development locks in.
iOS Development
TestFlight builds in slices — auth, notifications, payments and API as one product.
Testing & QA
Device QA for notch, Dynamic Type, permissions, accessibility and review-risk features.
App Store Release & Support
Metadata, screenshots, review buffers and iteration once the version is live.
Why professional iOS app development still matters in 2026
iOS review is a product constraint, not paperwork. Payments, sign-in, data and “why do you need this permission” sink apps. A London business that treats the App Store as an afterthought rewrites in a panic.Design Dev ships iOS with TestFlight cadence, a release owner and honest advice on IAP vs web payments. If Flutter or a PWA is cheaper for your audience, we will say so.
- iPhone products designed for how customers hold the phone
- App Store listing, privacy and review planned from day one
- Sign in with Apple when Apple requires it
- TestFlight groups for stakeholders and QA
- Push that is opt-in honest
- Backend ready before you hit Submit
- Crash monitoring and versioning
- Support as iOS versions ship
