Overview

Mobile apps that fit the platform you already run

Most mobile apps are part of a bigger system: a SaaS platform, an operations tool or an online store. We build React Native apps with Expo that plug into that system cleanly, through a secure token-based API designed for mobile.

Our mobile developers are full-stack engineers. They can design the API the app needs, handle authentication and offline behaviour, and still deliver a smooth, native-feeling interface on both iOS and Android.

We have built apps for staff on shared restaurant tablets as well as customer apps on personal phones, and we handle the build pipeline and store submission so launch day is predictable.

We design or extend the API your app needs, with token auth, rate limits and versioning.

Kiosk and shared devices

Apps that switch between personal and shared-tablet modes, with PIN or badge sign-in for staff.

Release pipeline

EAS builds, TestFlight and internal testing tracks, store listings and submission support.

Over-the-air updates

Ship fixes quickly with Expo updates while keeping store releases for larger changes.

FAQ

Frequently asked questions

Why React Native instead of fully native apps?

For most business apps React Native gives you both platforms from one codebase with native performance where it matters. If your app depends heavily on platform-specific features we will tell you, and we can add native modules where needed.

Do we need our own developer accounts?

Yes. Apps should be published under your Apple Developer and Google Play accounts so you own the listings. We guide you through setting them up.

How quickly can a developer start?

Usually within one to two weeks of signing, depending on the scope and the skills needed. We start with a short onboarding call to agree access, tools and the first sprint.

Which time zones do you cover?

We are based in Bangladesh (GMT+6) and schedule overlap with UK and European working hours every day. For US clients we agree a fixed overlap window for calls and reviews.

Do you sign an NDA and who owns the code?

Yes, we sign an NDA before you share sensitive details. You own all code, designs and documentation produced for you once invoices are paid.

Can we interview the developer first?

Yes. For dedicated and part-time engagements you meet the developer before work starts, and the founder stays involved for code review and architecture.

What if it is not working out?

Tell us early. We will adjust the setup or replace the developer. Monthly engagements can be ended with a short notice period, and we hand over code and documentation cleanly.
