Mobile app development for iOS and Android from one codebase

Two native codebases means two teams, two release cycles and two sets of bugs. Unless you need deep platform-specific hardware access, React Native gets you both stores from one codebase — which halves the build and, more importantly, halves what it costs to maintain for the next three years. We build, publish and keep apps in the stores.

You probably need this if

  • It only works on good wifi
  • The store rejected it
  • Two codebases, double the cost
  • Nobody updates it
Before you brief anyone

Where these projects go wrong

Four failure modes we see repeatedly. Knowing them up front is most of the battle.

  1. 01

    It only works on good wifi

    Field staff lose connection and the app loses their work. Offline tolerance has to be designed in, not patched on.

  2. 02

    The store rejected it

    Privacy declarations, permissions, account deletion, content ratings — store review fails for policy reasons far more often than technical ones.

  3. 03

    Two codebases, double the cost

    Every feature is built twice, tested twice and drifts apart. Maintenance quietly becomes the biggest line item.

  4. 04

    Nobody updates it

    Apps need releases for OS updates whether or not you add features. Skip that and it stops installing on new phones.

Scope

What you get

Concrete deliverables, not a statement of ambitions.

Discuss your scope
  • React Native and Expo application
  • iOS and Android builds from one codebase
  • Offline-tolerant data sync
  • Push notifications
  • Biometric or PIN login
  • App Store and Google Play submission
  • Store listing assets and privacy declarations
  • Over-the-air update pipeline
How it runs

The engagement, step by step

  1. 01

    Decide what belongs on a phone

    Not every feature should be in the app. We cut the surface to what people genuinely do standing up, one-handed, in a hurry.

  2. 02

    Design for the worst network

    We assume patchy connectivity from the start — queued actions, local cache, clear sync state — rather than treating offline as an error.

  3. 03

    Build and test on real devices

    Mid-range Android phones, not just the latest iPhone in a simulator. That is what most of your users are actually holding.

  4. 04

    Publish and maintain

    We handle submission, review responses and the ongoing OS-update releases that keep the app installable.

Outcomes

Benefits & business outcomes

What changes when this work is done properly — not activity metrics, business results.

  • 01

    Both stores from one codebase

    Mobile app development on React Native ships iOS and Android together, so a feature is built once and maintained once — not duplicated across two native teams.

  • 02

    Offline work that actually syncs

    Queued actions, local cache and clear sync state are designed in from the start, so field staff do not lose data when the connection drops.

  • 03

    Store submission handled properly

    Privacy declarations, permissions, account deletion and review responses are part of mobile app development here — policy rejections are more common than code failures.

  • 04

    Updates that keep it installable

    Over-the-air updates and periodic OS-compatibility releases mean the app still installs on new phones two years after launch.

Why BuildsInfinity

Why choose BuildsInfinity

Practical reasons teams choose BuildsInfinity for mobile app development — grounded in how we actually work, not a slogan list.

  1. 01

    We will tell you native vs cross-platform honestly

    Mobile app development does not always need two native codebases. We recommend React Native unless you genuinely need deep hardware access on day one.

  2. 02

    Tested on mid-range Android, not just simulators

    Real devices and patchy networks are how your users experience the app. That is how we test before store submission.

  3. 03

    Published into your developer accounts

    Listings, assets and credentials live under your Apple and Google accounts — mobile app development where you own the store presence, not us.

  4. 04

    Maintenance priced honestly

    Apps need releases even when you add no features. We offer a retainer for OS updates and crash monitoring rather than pretending launch is the finish line.
