On the web you can hotfix.

Here, a stranger reviews your build. Native iOS and Android engineers who have shipped through the gates enough times to design around them — flags, phased rollouts, and an API that keeps serving the users who never update. Full-time in your team, on our payroll.

Six gates between “done” and “a user has it”

Roughly two weeks of calendar time you cannot compress, and one gate you do not control at all. Engineers who have not been through it plan as though shipping is instant, and then the roadmap slips every single sprint.

Code complete

Feature merged behind a remote flag, so the decision to expose it is not the same decision as the decision to ship the binary.

Internal build

CI 15 min

Signed, versioned, symbols uploaded. Fastlane or Xcode Cloud — never a laptop with someone's certificate on it.

TestFlight / Internal track

QA + stakeholders 1–2 days

Real devices, real accounts, the specific Android models your analytics say your users have.

Store review

Apple / Google 24–72 hrs The gate you do not control. Most rejections we see are account deletion missing, a privacy label that does not match the SDKs, a login wall on content that does not need one, or a crash on the reviewer's first launch.

Phased rollout

Your team 5–7 days

1% → 10% → 50% → 100%, watching crash-free sessions at each step, with the halt criteria agreed before the release, not during it.

The long tail

Nobody, usually Months A third of your users will be two versions behind for a long time. Your API has to keep serving them — which is a backend decision made on mobile's behalf.

Native or cross-platform

Four reasons to pay for native

If none of these describe your app,



we will point you at React Native or Flutter and quote you less. That advice costs us money and saves you more.

React Native instead Flutter instead

BLE, NFC, accurate camera control, CarPlay or Android Auto, health and sensor APIs on day one of an OS release.

Performance is the product

Real-time video, AR, games, anything where a dropped frame is a user-visible defect rather than a nuisance.

The platform look is the product

Apps where the iOS version should feel like iOS and the Android version should feel like Android, not like each other.

Regulation is the product

Banking, health and government apps where the security review asks about keychain, attestation and certificate pinning specifically.

Seniority

Three bands, 7–12 days to start

Mid-level

3–5 yrs $30–36/hr

Builds screens and features against an agreed architecture, on one platform.

Senior

5–8 yrs $36–46/hr

Owns a platform end to end, including the release train and the store relationship.

Lead

8+ yrs $46–62/hr

Runs both platforms, sets the shared API contract, and owns the rollout and rollback policy.

Tell us which platform is on fire

A rejected submission, a crash rate that will not come down, an app nobody has updated since the last OS release. All three are things we have fixed.
