Service 03 / 10 / Build From $58k/mo × 5–7 weeks to TestFlight

Mobile apps
built to pass review.

Native iOS and Android — or React Native when honest. We design for the platform, ship through real CI, and instrument from day one. No “web wrapper” pretending to be an app.

Native where it matters,
shared where it doesn’t.

A platform-honest stack: Swift & Kotlin for surfaces that need it, RN where shared logic earns its keep.

A / iOS

Swift & SwiftUI

Modern Swift, with UIKit interop where SwiftUI still bites.

  • Swift 6 / iOS 17+ strict concurrency
  • SwiftData / Core Data hybrid OK
  • WidgetKit first-class
  • App Clips where useful
  • StoreKit 2 subscriptions
B / Android

Kotlin & Compose

Jetpack Compose with the right escape hatches.

  • Kotlin 2.0 KMP-ready
  • Jetpack Compose Material 3
  • Room / SQLDelight choice
  • WorkManager reliable BG
  • Play Billing subscriptions
C / Cross-platform

React Native

When 80% of the surface is shared logic, not chrome.

  • New architecture Fabric + TM
  • Expo prebuild default
  • Native modules when needed
  • Hermes always
  • Per-screen rationale written
D / Release

CI & review

Reviewers approve the build, not your demo.

  • Fastlane CI every push
  • TestFlight < 30 min
  • Internal track Android
  • Crash-free ≥ 99.5%
  • Phased rollout default

In your accounts
on day one.

Apple Developer, Google Play, Firebase, Sentry — all under your tenancy. You own the listings, the certs, and the customer data.

01

Two native binaries

iOS .ipa and Android .aab from a green CI pipeline. Signed with your certs, in your tenancy.

02

Design system

Tokenized in code: typography, colors, spacing, motion. Same tokens consumed by iOS, Android and RN.

03

Store presence

Listings, screenshots, privacy nutrition labels, App Tracking Transparency wording — all reviewed and shipped.

04

Observability stack

Crash reporting (Sentry/Crashlytics), structured logs (Datadog/Logz), real-user performance, opted-in analytics.

05

Release train

Weekly TestFlight, biweekly App Store. Release notes generated from PR titles. Rollback plan written down.

06

Accessibility review

VoiceOver + TalkBack tested by humans, not lint. Dynamic Type up to XXL. Contrast against WCAG 2.2 AA.

Three shapes
of mobile work.

From single-platform pilot to dual-platform with full release operations.

Single platform

Solo squad

From $58k/mo · 2 engineers
  • Pick iOS or Android
  • Fastlane CI + Sentry baseline
  • 5–7 weeks to TestFlight
  • Single-region backend assumed
Most common

Dual squad

From $96k/mo · 3 engineers
  • iOS + Android in parallel
  • Shared design tokens
  • Phased rollout on both stores
  • Crash budget tracked weekly
Full release ops

Release train

From $148k/mo · 4–5 engineers
  • Two-platform + backend together
  • On-call for store-impacting bugs
  • A/B testing infrastructure
  • Localization for top 5 markets

Seven weeks
to TestFlight.

Mobile rewards a steady cadence. Internal builds every push, external builds every Friday, store releases on a known calendar.

01 / Week 1

Platform brief

Native-vs-RN per surface decision, written. Provisioning, CI, signing, crash reporting wired up before line-of-business code lands.

02 / Week 2–4

Core flows

Auth, profile, primary user journey shipped to internal testers. Telemetry that proves the flow works, not just builds.

03 / Week 5–6

Polish for review

App Tracking Transparency, privacy nutrition labels, accessibility passes, in-app purchase or subscription testing.

04 / Week 7+

Release train

TestFlight or internal track open to your team. Phased store rollout once crash-free sessions hold above 99.5% for a week.

Things buyers ask
on the first call.

If something isn’t answered here, ask in your intro email — we keep this list short on purpose.

Do you do React Native or Flutter exclusively?+

No. We pick per surface. Login & settings: usually RN. Camera, AR, real-time audio: usually native. We write down the choice and the reason so it’s reviewable.

What about offline-first?+

Yes — every project gets a sync layer review in week 1. We default to event-sourced local stores with conflict-free merge where possible, and a written degradation strategy where not.

Can you ship to enterprise MDM?+

Yes. We’ve shipped to Jamf, Intune, VMware Workspace ONE. Add about a week for MDM-only build channel setup and configuration profile authoring.

How do you handle Apple’s reviews?+

We pre-flight against the Guidelines checklist in week 5, file precautionary App Review notes, and time first submission to a quiet day. Rejection rate is < 8% on first submission across our clients.

Got something hard
that needs to be real?

Send a paragraph about the problem. We’ll come back inside 48 hours with a written take — team shape, cost envelope, riskiest assumptions.
