What you get

Concretely, by the time we hand over

Single codebase for iOS + Android — Expo prebuild for native modules when needed
Authenticated user flow with push notifications and offline-first storage
TestFlight build before week three; App Store + Play Store submission included
OTA updates via Expo Updates so you ship fixes without a store review
App store listings (screenshots, copy, privacy nutrition labels) handled

Why this works for Los Angeles

The local math

LA is the underrated tech hub of 2026. Defense in Costa Mesa (Anduril, Apex Space). Healthcare and media-tech in Santa Monica. Creator-economy products everywhere from Venice to El Segundo. Hiring senior engineers means competing with $250K offers from VCs who won't admit they pay SF-level comp. We don't pretend otherwise — we just ship, flat-priced.

Year-one outlay for a single senior hire in Los Angeles: ~$310K. Our mobile app development engagement starts at $10,000.

Why us

Why founders in Los Angeles pick us for this

01
Senior engineer who has shipped both stores — store submission isn't a learning experience here
02
We pick React Native vs native based on the actual feature list, not a default
03
Performance-aware: list virtualization, image caching, JS-thread budget — measured, not hoped
04
Push, analytics, crash reporting, deep links, OTA — wired correctly first time

FAQ

Common questions about mobile app development in Los Angeles

How fast can you start?

Most builds begin within seven days of the first call. We don't sell discovery — we go from problem statement to first deploy on the same day-one timeline.

Is the price really flat?

Yes. After a 30-minute call we send a single number and a scope you can accept or reject. No hourly billing, no change-order games. If we underestimate, we eat it.

React Native or native (Swift/Kotlin)?

React Native by default — 90% of features are identical and you ship to both stores at once. Native if you have hard requirements (live activities, complex camera, low-level audio, watch app).

Do you handle App Store submission?

Yes — Apple Developer + Google Play account setup (or working in yours), screenshots, privacy declarations, review responses if rejected. Most apps clear review in 24–72 hours.

Who owns the code?

You do, from commit one. The repository is created in your GitHub org. Infrastructure is provisioned in your cloud account. We don't host your stack on ours and we don't lock you in.
