B1Mobile app development — bay B1

Mobile apps, built to be maintained.

Apps that start fast, survive poor signal, respect battery and privacy, and can be picked up by another engineer without a séance.

Scope

What this covers

We build for iOS and Android. Where an app depends heavily on device hardware, background processing or platform-specific interface conventions, we recommend native code. Where it is mostly forms, lists, content and accounts, a cross-platform framework usually saves time and money with little compromise. We explain the trade-off for your particular case before you commit.

Offline behaviour, error states, push notifications, deep links and accessibility are scoped explicitly — they are where most of the hidden effort in mobile work lives.

    Prototype

    Clickable prototype tested with representative users; main journeys revised.

  3. 03

    Sprint build

    Two-week sprints. A TestFlight / Play internal build at the end of each.

  4. 04

    Verification

    Device matrix testing, screen-reader passes, performance and security review.

  5. 05

Questions

Asked on the desk

Can you take over an app someone else built?

Yes, after a fixed-scope code and infrastructure review. You get a written report and a recommendation before any further commitment.

Will the app work offline?

If it needs to, we design for it from the start. Retro-fitting offline support is expensive, so we ask early.

Who owns the code?

You do. Repositories and developer accounts are set up under your organisation.
