Capabilities

What we ship

Production-grade mobile builds: native where it matters, cross-platform where it pays.

  • React Native + Expo

    One codebase for iOS and Android, OTA updates for instant fixes, and EAS builds signed and shipped every week.

  • Native iOS + Android

    Swift and Kotlin when the platform is the point: AR, Bluetooth hardware, widgets, or heavy animation.

  • Flutter builds & takeovers

    We build new Flutter apps and take over existing Flutter codebases: storefronts, delivery apps, and admin surfaces.

  • Offline-first + sync

    Field and delivery apps that keep working with no signal: local database, sync queue, and conflict handling.

  • Push + deep links

    FCM + APNs campaigns, universal links that open the right screen, and delivery metrics you can actually track.

  • Store submission

    Listings, screenshots, privacy declarations, and review back-and-forth: both stores, handled end to end.

In practice

A closer look at how we build

Built for the real world: offline first

Couriers in basements, field teams on patchy 4G, warehouses with dead zones: real apps lose signal. We design the data layer local-first, so the app keeps working and syncs cleanly when the connection returns.

  • Local-first database: WatermelonDB, Realm, or SQLite
  • Sync queue with conflict resolution
  • No data loss through network drops

A working build in your hands every week

You never wait for a big reveal. From week three there's a signed build on TestFlight and the Play internal track. You tap through real screens on your own phone and steer the product while it's being built.

  • First signed TestFlight build by week 3
  • OTA channel for hotfixes without a store review
  • Crash monitoring wired from the first build

Engagement that respects your users

Push that lands on the right screen, not just the home tab: segmented campaigns over FCM and APNs, universal links into any screen, and per-campaign delivery and open metrics so you know what works.

  • Segmented push via FCM + APNs
  • Universal links and app links into any screen
  • Event analytics from day one: Amplitude, PostHog, or Firebase

Choosing an approach

React Native, native, or PWA?

The platform call is the most expensive decision in a mobile project. We make it with you, with data, in discovery.

React Native + Expo

One codebase, two stores

Best for most product apps: commerce, delivery, services, and internal tools.

  • One team and one codebase covering both stores
  • OTA updates ship fixes in minutes, not review cycles
  • Native modules where the platform is needed
  • Heavy 3D/AR or very custom platform UI can outgrow it

Native (Swift / Kotlin)

Maximum platform power

Best for: AR, Bluetooth hardware, widgets, watch apps, and animation-heavy experiences.

  • Every platform API available on day one
  • Best possible performance and platform feel
  • First in line for new OS features
  • Two codebases: roughly double the build and maintenance effort

PWA

No store, no install

Best for: MVPs, internal tools, and reach-first products where install friction matters.

  • One URL works everywhere and updates instantly
  • No store review and no store commission
  • Home-screen install and offline caching
  • Limited iOS capabilities (push, background) versus a real app

Unsure? Bring us the product idea. The platform recommendation is part of the free discovery call.

How we work

From idea to the App Store in four moves

A transparent path with a working build in your hands every week.

  1. 01

    Discovery

    Week 1–2

    Scope, platform call, and a clickable prototype before a line of production code.

  2. 02

    Build

    Week 2–6

    Weekly TestFlight and internal-track drops. You watch it take shape live.

  3. 03

    Ship

    Week 6–8

    Store metadata, screenshots, signing, and review handling, end to end.

  4. 04

    Support

    Ongoing

    Crash monitoring, OTA fixes, and OS-version upkeep after launch.

Shipped work

One platform, three apps

From the Olloyo delivery-platform engagement: customer ordering, courier logistics, and vendor management. One backend, three surfaces.

Customer appOlloyoBrowse multi-vendor catalogues, order, pay, and track the delivery live.
Courier appOlloyo CourierRoute, pickup, and delivery flow with live status, built to survive patchy mobile networks.
Vendor appOlloyo StoreOrder queue, menu management, and daily revenue at a glance for store owners.

Screens shown are stylised representations of the shipped product.

Ways of working

Engagements that fit the job

Every app is quoted per scope after a free discovery call. These are the shapes it can take.

Fixed-scope MVP

Typical: 6–12 weeks

A defined feature set, a fixed quote, and a store-submission date. The right shape for a first launch.

  • Fixed quote and timeline agreed up front
  • Weekly TestFlight builds on your own phone
  • Store submission for both stores included

Sprint retainer

Monthly cadence

Post-launch product development in monthly sprints: features, experiments, and store releases on a steady rhythm.

  • Predictable monthly capacity
  • OS-version upkeep and dependency updates included
  • Crash triage and OTA hotfixes included

Team extension

Embedded with your team

Our mobile engineers join your repo, your standups, and your release train, with our review discipline in tow.

  • Works in your repo and your process
  • Direct communication with the engineers doing the work
  • Scale up or down as the roadmap needs

We pick based on performance and team velocity. React Native or Flutter wins for most product apps; native iOS/Android wins when AR, BLE, or platform APIs dominate. The recommendation is part of discovery.
