Mobile Engineering

We build the mobile apps your roadmap keeps postponing.

From discovery to the App Store — NextMobi designs, builds, and maintains mobile products for teams that need senior engineers now, not next quarter.

What we do

End-to-end mobile engineering

Six disciplines under one roof, so the handoffs that usually break projects happen inside the team instead of between vendors.

Native iOS & Android

Swift and Kotlin apps built the platform way, with the performance and polish users expect from a first-party experience.

Cross-platform Apps

One Flutter or React Native codebase, two stores, half the maintenance — for products where shared logic outweighs platform-specific depth.

Backend & APIs

The services your app talks to: auth, sync, payments, push, and the observability that keeps them honest in production.

Product & UI/UX Design

Flows, screens, and a design system your engineers can actually build — delivered as components, not as static mockups.

QA & Release Ops

Automated suites, real-device coverage, and CI that pushes signed builds to TestFlight and Play Console on every merge.

Maintenance & Modernization

SDK upgrades, OS deprecations, and rescuing the legacy codebase nobody on your team wants to open anymore.

How we work

Five steps, no black boxes

You see a working build every two weeks. If a sprint goes sideways you hear it from us first.

  1. 01

    Discover

    A short paid discovery: goals, constraints, and a scoped backlog. You leave with an estimate you can budget against — and it is yours whether or not we build it.

  2. 02

    Design

    Flows and screens iterated with you weekly, until the prototype answers every open product question.

  3. 03

    Build

    Two-week sprints, each ending in an installable build. No month-long silence, no integration surprises at the end.

  4. 04

    Ship

    Store submission, staged rollout, crash monitoring, and the release checklist we run so launch day is boring.

  5. 05

    Iterate

    Post-launch analytics, experiments, and a maintenance retainer sized to what the product actually needs.

Selected work

Problems we were handed, and what shipped

Client names are withheld under NDA; the numbers are from post-launch reporting.

Fintech

Neobank onboarding

Problem — a 14-screen KYC flow was losing 60% of applicants before they ever created an account.

Shipped — rebuilt in Swift with resumable state and on-device document capture. Completion up 38%.

Logistics

Driver dispatch app

Problem — field crews worked through dead zones where the existing web app was simply unusable.

Shipped — an offline-first Flutter app with conflict-resolving sync. 12,000 deliveries logged daily, connection or not.

Health & Fitness

Coaching platform

Problem — a React Native codebase four SDK generations behind, blocked from submitting to the App Store.

Shipped — modernized, given a design system, and cold start cut from 4.2s to 1.1s.

Working together

Three ways to engage us

Dedicated team

A cross-functional squad — engineers, designer, QA — working only on your roadmap. Billed monthly, cancel with 30 days' notice.

Fixed-scope project

Defined deliverables, fixed price, fixed date. Best when requirements are settled and the finish line is already clear.

Staff augmentation

Senior mobile engineers embedded in your existing team — your repo, your board, your standups.

About us

An engineer-led studio

The people who scope your project are the people who write the code. There is no account layer between you and the team building your app, and no discovery document written by someone who will never open the repository.

We work across time zones with clients in North America, Europe, and Asia, deliberately overlapping hours so a blocking question never waits a full day for an answer.

  • Code and IP are yours — full repository access from day one, transferred outright on completion.
  • Weekly visible delivery — a running build every sprint, not a status report about one.
  • Senior engineers only — no subcontracting, no juniors billed at senior rates.
  • We stay after launch — maintenance retainers, not a handoff and a goodbye.
