Engineering Services

Mobile Application Development

Practical mobile tools for field teams and service businesses.

Offline-aware and online mobile applications for quoting, field operations, customer follow-up and internal mobile workflows.

Who this service is for

  • Home-service and field teams that work away from a desk
  • Businesses that need quoting, scheduling or payment capture on mobile
  • Teams that need shared mobile and web product foundations

Common business challenges

Unreliable connectivity

Field work happens where network quality is inconsistent.

Desktop-only processes

Staff return to the office to finish quotes, invoices or follow-ups.

Fragmented customer history

Calls, notes and payments are not attached to the same customer record.

What EH DESIGN delivers

  1. Mobile workflow design

    Screens and states optimized for one-handed, on-site use.

  2. Offline strategy

    What works offline, what syncs later and how conflicts are handled.

  3. Cross-platform implementation

    React Native / Expo apps with shared TypeScript foundations where suitable.

  4. Release readiness

    Build, store submission and update guidance.

Typical capabilities

  • Offline-first local storage
  • Quote and document generation
  • Customer and payment records
  • Reminders and follow-up workflows
  • Secure local data handling
  • Sync strategies when connectivity returns

Delivery approach

How mobile projects are approached

We design for the real working conditions of the user: limited time, interrupted attention and imperfect connectivity. Features that do not survive those conditions do not ship in the first release.

  • Prototype critical mobile flows early
  • Define offline behavior before polish
  • Keep the first release focused on the daily job
  • Plan store and update operations from the start

Technology considerations

  • React Native and Expo
  • TypeScript across the mobile codebase
  • SQLite for offline storage
  • Secure local persistence patterns

Frequently asked questions

Most product work starts with React Native / Expo for shared delivery. Fully separate native apps are considered only when product constraints require them.
