● Not viewed
// Stage 01 //

Discovery

One to two weeks. We map platform targets, store requirements, and release plan. You get a technical spec plus a submission checklist before a line of code is written.

Build

Weekly TestFlight and internal-track builds. Real-device testing across iOS and Android from week one. You get a working app on your phone the first Friday.

Handoff

App Store submission, Play Console setup, crash reporting wired, release notes written. Documented code, trained team, or a retainer for ongoing OS updates.

Common questions

Common questions
How do you choose React Native vs native?
React Native when the app is mostly UI and business logic that runs well on both platforms, and you want one codebase. Swift or Kotlin when the app hits platform-specific APIs hard – Core Bluetooth, ARKit, camera-intensive workflows, or anything where the 60fps budget is tight.
What does it cost?
Fixed-price for well-scoped apps, time-and-materials for exploratory work. A production-ready cross-platform app typically lands between $40k and $180k depending on complexity and backend scope. We quote after discovery.
How do App Store reviews affect the timeline?
Build two to seven days into the release schedule for App Store review. Play Store is faster, often same-day. We prepare review notes and demo accounts upfront, which prevents the 60% of rejections that come from reviewers being unable to access gated features.
Do you handle ongoing OS updates?
Yes, via a retainer. iOS and Android release major versions yearly, and deprecations typically bite twelve to eighteen months later. We keep the app building against current SDKs, ship timely compatibility releases, and flag breaking API changes before they strand users.
How do offline-first apps work?
Local storage is the source of truth. The app reads and writes to SQLite or Realm immediately. A sync engine reconciles with the server when online, using last-write-wins or CRDT-based merging depending on the conflict shape. Users never see a spinner waiting for a network.
