OptionFlow

One codebase, both stores, no review roulette at launch.

React Native for iOS and Android — push, offline sync, payments, and store submission included, not extras. Tested on real devices, crash-monitored, and handed over with signing and docs.

What you get

  • StackReact Native, TypeScript, Firebase
  • PlatformsiOS and Android, one codebase
  • Native featuresPush, camera, offline, biometrics
  • QualityStrict types, E2E on real devices, crash-free >99.5% target
  • DeliveryTestFlight builds, store submission, OTA updates

Sound familiar?

  • Your web product works, but customers keep asking where the app is

  • You got quotes from two separate native teams and the budget didn't survive

  • Your app got rejected by App Store review and the email doesn't say what to fix

  • Every bug fix means days of waiting for store approval before users see it

  • The freelancer who built the app is gone, and nobody can produce a release build

  • Push notifications, offline mode, or payments were "coming later" and never came

What we build

  1. 01

    iOS & Android from one codebase

    React Native sharing ~90% of code, native modules where RN stalls, Hermes enabled, upgrade plan owned — the escape hatch is defined before you need it.

  2. 02

    Native device features

    Push with an opt-in strategy, offline-first with conflict resolution, biometrics, deep links. Handles OS-killed background work, permission denials, and sync merges that AI demos skip.

  3. 03

    Payments & subscriptions

    In-app purchases and subscriptions via Apple and Google, Stripe where the rules allow, with server-side receipt validation and entitlement sync — no free premium from replayed receipts.

  4. 04

    Store launch & OTA updates

    Submission, rejection handling, signing, and over-the-air updates with rollback. Critical fixes bypass the review wait; native changes are flagged upfront so there are no surprise delays.

How it works

  1. 01

    Discovery call

    Tell us what the app should do, who uses it, and whether you already have a web product or API. No commitment.

  2. 02

    Scope & proposal

    A fixed-scope plan with price, timeline, and a clear call on React Native versus native — before any code is written.

  3. 03

    Build in sprints

    A new build on your phone every one to two weeks via TestFlight and internal testing, with demos and room to adjust.

  4. 04

    Launch & support

    Store submission, review handling, crash monitoring, and a support window so launch day is boring.
