Capabilities

What we ship

Every engagement starts with a clear list of what we are responsible for and what your team owns.

  • Native iOS and Android development with Swift and Kotlin
  • Cross-platform apps with React Native and Expo
  • Offline-first sync, conflict resolution, and queueing
  • Push notifications, deep links, and lifecycle analytics
  • App-store submission, review responses, and release engineering
  • Field-team and operator apps with role-based access
How we engage

A predictable path from scoping to handoff

Every engagement runs the same path so your team always knows what is happening this sprint and what ships next.

  1. Mobile scoping sprint

    Two weeks to lock the offline model, sync strategy, push notification taxonomy, and the smallest releasable mobile slice.

  2. Vertical slice in TestFlight

    First TestFlight build within four weeks: auth, offline queueing, push, and the highest-leverage operator workflow.

  3. Release cadence

    Two-week sprints with a TestFlight or internal-track build per release and a measured operator outcome.

  4. Mobile handoff

    Release runbooks, signing certs, and pairing sessions move ownership to your team. We stay on a small retainer for OS upgrades.

Outcomes

What success looks like in production

Outcomes from recent engagements. We measure and report them weekly during the engagement, not just at the end.

  • First production app-store release within twelve weeks of kickoff
  • Operator task completion rates 30–50% higher on rebuilt mobile flows
  • Offline-first sync that never loses a write during real network outages
  • Crash-free sessions above 99.5% on production traffic
  • App-store review pass on the first submission for new clients
Technology stack

A boring, audited stack

We default to the tools with the longest production track record. Boring is a feature, not a bug.

FAQ

What buyers ask us

Are you a mobile app development company that ships native and cross-platform?
We are a mobile app development company that ships both. Cross-platform on React Native and Expo for B2B operator apps where one codebase serves iOS and Android. Native Swift or Kotlin when device APIs or performance demand it.
Do you handle the full mobile app store submission process?
Yes. Every mobile app development engagement includes app-store submission support: App Store Connect setup, signing certificates, review responses, and release engineering. We have shipped through real Apple and Google review cycles.
Can you build mobile apps that work offline-first?
Offline-first sync is the default for every B2B mobile app we ship. WatermelonDB, RxDB, or PowerSync for the sync layer, plus conflict resolution patterns that hold up when field teams reconnect after a full day offline.
Do you build mobile apps for marketplaces and field teams?
Most of our mobile app work is for marketplaces and field teams — operator apps, dispatch apps, and last-mile delivery apps. Push notifications, geo-fencing, and proof-of-delivery flows are bread-and-butter.
What is the typical mobile app development engagement length?
Mobile app development engagements typically run twelve to twenty weeks to a first production app-store release. Two-week sprints with TestFlight or internal-track builds per release, then a small retainer for OS upgrade cycles.
