Apps for the people who are never at a desk.

Drivers, engineers, store managers and auditors — working in basements, warehouses and dead zones. Plus customer-facing products that earn a place on the home screen.

The decision that matters

Native, cross-platform or web — settled in the first week

Nearly every mobile budget is won or lost here. We pick on your requirements, not on what we prefer to write.

Cross-platform

One Flutter or React Native codebase across iOS and Android. Right for most field and customer apps — one team, one release, roughly half the cost of two natives.

Default unless something rules it out

Fully native

Swift or Kotlin when you need deep hardware access — continuous barcode scanning, BLE peripherals, background location, or camera work at frame rate.

When the hardware is the product

A web app on a phone

Sometimes you do not need an app at all. If it is occasional, online and internal, a responsive web app saves you two app-store relationships.

The answer we give more often than you'd expect
What we build

Four kinds of app, each with a different hard part

Store accounts, signing certificates and release pipelines stay in your name — we operate them, you own them.

01

Field & delivery apps

Drivers, engineers and auditors working where the signal is not. The hard part is conflict resolution, not screens.

·Offline-first storage with a queue that survives a force-close
·Proof of delivery: photo, signature, GPS and timestamp
·Writes back to the ERP so the delivery closes the invoice
8–14 weeks
02

Warehouse & scanning apps

Picking, put-away, cycle counts and goods receipt, on phones or rugged handhelds.

·Continuous barcode and QR scanning without tapping between reads
·Batch, serial and expiry capture at the point of movement
·Glove-friendly targets and one-handed layouts
6–12 weeks
03

Customer-facing products

Loyalty, ordering and self-service apps that have to survive a one-star review and a store review queue.

·Payments, wallets and UPI with proper failure handling
·Push notifications people do not immediately disable
·Biometric sign-in, deep links and store-review readiness
10–16 weeks
04

Rescue & release management

An app that exists but crashes, drifts or cannot be shipped because the person who built it has gone.

·Crash triage, dependency and SDK upgrades, store compliance
·Signing keys and store accounts recovered into your name
·An automated release pipeline so shipping stops being an event
from 3 weeks
What field apps get wrong

Eight things that decide whether the floor keeps using it

An app the team abandons in month two costs more than no app. These are the reasons they abandon it.

Offline is the default, not a mode

Everything is written locally first and synced after. A basement or a dead zone should be uneventful, not a lost afternoon.

Conflicts resolve by rule

Two people editing the same record offline is normal. The merge rules are agreed with your operations team, not invented by the sync library.

Battery and data budgeted

A shift is ten hours. Location polling, image sizes and sync frequency are tuned so the phone survives it and the data plan does too.

Built for the real device

Tested on the mid-range Android your team actually carries, in sunlight, with gloves — not only on a new iPhone at a desk.

One-handed and few-tap

The common task is reachable with a thumb while holding a box. Every extra tap is multiplied by a hundred drops a day.

Honest sync state

The person can always see what has reached the office and what has not. Ambiguity here is what makes people keep a paper backup.

Crash reporting from day one

Field staff do not file bug reports, they stop using the app. Crash and error telemetry tells you before the usage numbers do.

Shipping is automated

Signed builds, staged rollout and over-the-air updates where the platform allows — so a fix reaches the fleet in hours, not a release cycle.

The stack

Chosen per app, not per agency preference

Store accounts, certificates and the repository stay in your name from the first build.

Mobile questions we get asked first

Answered the way we'd answer them on the call.

Ask us something else
Flutter or React Native — which do you use?

Both, chosen per project. Flutter when the UI is custom and consistency across platforms matters; React Native when you have web React skills in-house and want to share people and code.

Do we need iOS and Android from the start?

For field apps, usually Android only — that is what the fleet carries, and it halves the store overhead. Customer apps normally need both. We check your actual device mix before deciding.

Who owns the store accounts and signing keys?

You do, in your company's name, from the beginning. We are added as a developer. This is the single most common thing we have to rescue from a previous agency.

Will it work with our Odoo or existing backend?

Yes — that is the usual brief. The app talks to a proper API layer rather than the database, so a driver marking a delivery done closes the real record rather than a copy.

How long does store approval take?

Usually one to three days on both stores now, but a first submission can be rejected on privacy declarations or account deletion rules. We prepare those before submitting, and budget a week for the first release.

What does maintenance actually involve?

Mobile does not stand still: two OS releases a year, SDK deprecations and periodic store policy changes. Budget for a small ongoing retainer or plan a refresh every twelve to eighteen months.

Tell us about the shift, not the screens.

Who carries the phone, where they lose signal and what they write on paper today. That conversation decides the whole build.
