Mobile app development

Apps that ship, reach the store, and get used.

We've put over a million users on apps we wrote — consumer products, field tools and marketplaces. Fixed price, first release in four to eight weeks, and every line of it is yours.

  • iOS, Android and React Native
  • Offline-first for field teams
  • AI search, chat and capture built in
  • Store submission handled end to end
What you get

Everything an app needs to survive contact with real users

The build is a fraction of the work. Integrations, store review, offline behaviour and analytics are what decide whether it succeeds.

Native and cross-platform

React Native when you want one codebase on both stores, Swift or Kotlin when the app needs to do something only native can. We'll tell you which your project actually needs rather than defaulting to whatever we prefer.

Offline-first architecture

Delivery drivers, technicians and warehouse staff lose signal constantly. We build local-first sync so the app keeps working in a basement and reconciles cleanly when it reconnects.

AI where it earns its place

Natural-language search, photo-to-form capture, smart reminders, in-app assistants. Real features that cut taps, not a chatbot bolted onto a settings screen.

Wired into your systems

Your ERP, CRM, payment gateway, delivery partner and accounting software. The app is the easy part — the integrations are where projects usually go wrong, and where we spend our time.

Built to pass review

Store guidelines, permissions, privacy manifests, data-deletion flows. We handle App Store and Play Store submission including the rejections, which almost everyone gets on their first attempt.

Analytics from day one

Events, funnels and crash reporting configured before launch, so you can see where users drop off in week one instead of guessing for a quarter.

The deal

No day rates, no scope drift

You get a fixed price and a fixed milestone plan. If we've scoped it wrong, that's our problem to absorb, not a change request for you to sign.

  • Fixed price agreed before development starts
  • Working build demoed every two weeks
  • Direct WhatsApp or Slack channel to the engineers
  • Repositories in your GitHub organisation from commit one
  • Cloud infrastructure in your AWS or Google Cloud account

Process

How an app project actually runs

Five stages, each with something you can see and judge at the end of it.

  1. 01

    Define the smallest launchable app

    Most app briefs contain three products. We separate what has to be in version one from what can wait, so you get to market and to real user feedback in weeks rather than quarters.

  2. 02

    Design and clickable prototype

    Full UI in Figma plus a prototype you can tap through on your own phone. You approve real screens before we build them.

  3. 03

    Sprint build with fortnightly demos

    A working TestFlight or Play internal build every two weeks, plus a direct channel to the engineers. You never wait until the end to see progress.

  4. 04

    Device QA and store submission

    Testing across real devices and OS versions, performance profiling, then submission. We deal with reviewer questions and resubmissions.

  5. 05

    Launch support and iteration

    We watch crash rates and analytics through the first weeks post-launch, fix what surfaces, and plan the next release with you.

Questions

Mobile app FAQs

Straight answers on cost, timeline and the things that usually go wrong.

How much does a mobile app cost in Singapore?

A focused app with a clear scope typically starts in the low five figures SGD. Marketplace or multi-role apps with heavy integrations run higher. We give a real range on the first call and a fixed written price before starting — quoting a number and holding it is the whole point.

React Native or native?

React Native for most business apps — one codebase, both stores, materially cheaper to build and maintain. Native when you need heavy background processing, deep hardware access, complex offline sync or maximum graphics performance. We recommend based on your requirements, not our convenience.

Do you handle App Store and Play Store submission?

Yes, end to end, including the rejections. First submissions get rejected regularly over privacy declarations, account-deletion requirements or sign-in rules. We know the common causes and deal with the back and forth for you.

Can you take over an app another agency built?

Frequently. We start with a short code and infrastructure audit so you know honestly what you've got — sometimes the right answer is to continue it, sometimes to rebuild the worst parts. We'll tell you which before you commit.

Will the app work without internet?

If your users need that, yes. Offline-first is standard for the field, delivery and logistics apps we build: work is stored locally and syncs with conflict handling when the connection returns.
