# Mobile Apps

> Your customers live on their phones. So should you.

iOS and Android from one codebase, including the hard parts — live camera, AR, offline use, biometric verification and push notifications — on the mid-range handsets your customers actually own.

- **Price:** quoted per project after a call — er@epsilon-labs.co
- **What moves the price above that floor:** Camera, AR and hardware integration, offline requirements, and how much backend has to be built alongside it.
- **Typical duration:** 6–10 weeks
- **Category:** Software

## The problem

A mobile app that only works on the developer's flagship phone is not finished. Most of your customers are on mid-range Android, on a patchy connection, with a camera that behaves differently from the one in the demo.

Those are the conditions to design for, not to discover at launch.

## What you get

- One codebase for iOS and Android, published to both stores
- Live camera and AR where the product needs it
- Offline-first data that syncs when the connection returns
- Biometric login and identity verification
- Push, SMS and in-app notifications
- The backend and admin portal it needs

## How it runs

- **Weeks 1–2** — Flows designed and tested on real mid-range devices.
- **Weeks 3–8** — App and backend built, weekly builds on your phone.
- **Weeks 9–10** — Store submission, launch, handover.

## This is for you if

- Consumer brands, service businesses, field teams
- Products that need the camera, location or offline use
- Companies whose website is doing an app's job badly

## This is NOT for you if

- Games and high-end 3D
- Apps that are really a website — build the website
- Wearables and embedded platforms

## Proof

Master Paints puts live AR colour on a customer's own wall from a mid-range Android phone, and an immigration case-management app we built verifies applicants biometrically.

## Questions

### Native or cross-platform?

React Native with Expo by default — one codebase, native modules where the product needs them.
