Our position

How we think about it

A mobile app that assumes constant LTE and a recent flagship device will fail the people who need it most. We design for the actual conditions: intermittent connectivity underground and in rural districts, mid-range Android handsets, expensive data and bright outdoor light. Offline-first is the default architecture, not a premium feature.

What you receive

  • Interactive prototype validated with real users in real conditions
  • Production applications for the agreed platforms
  • Offline sync engine with conflict-resolution rules
  • App Store and Play Store submission and review management
  • Crash reporting and usage analytics
  • Over-the-air update pipeline

Capabilities

What we actually build

  • Native iOS and Android development
  • React Native and Flutter cross-platform builds
  • Progressive web apps installable without an app store
  • Offline-first sync with conflict resolution
  • Barcode, QR, NFC and RFID capture
  • GPS tracking, geofencing and route optimisation
  • Push notification infrastructure
  • Mobile device management and enterprise distribution

Technologies we use

  • React Native
  • Expo
  • Swift
  • Kotlin
  • TypeScript
  • SQLite
  • WatermelonDB
  • Firebase
  • Sentry

Process

How a mobile applications engagement runs

Each phase ends with something you can look at and a decision you can make.

  1. 01

    Field research

    We go to the site. Underground, on the floor, in the vehicle — wherever the app will actually be used.

    1–2 weeks
  2. 02

    Prototype

    An interactive prototype tested with real users on real devices in real light.

    2–3 weeks
  3. 03

    Build

    Offline architecture first, then features on top of it. Retrofitting offline support never works.

    8–16 weeks
  4. 04

    Pilot

    A controlled rollout to one team, instrumented, with weekly feedback and fixes.

    4 weeks
  5. 05

    Scale

    Staged rollout, device management, training material and a support path.

    4–8 weeks

Questions

Mobile Applications — common questions

If yours is not here, ask Nova or send it to us directly.

  • Native or cross-platform?
    Cross-platform for most business applications — one codebase, faster iteration, no meaningful compromise. Native when you need deep hardware access, sustained camera processing or the tightest possible battery behaviour.
  • Do we need an app store presence?
    Not always. For internal workforce tools a progressive web app or enterprise distribution avoids review delays entirely and lets you ship a fix the same day.
  • How do you handle sync conflicts?
    With explicit, domain-specific rules agreed up front — last-write-wins is rarely correct for safety or inspection data. Anything the rules cannot resolve is surfaced to a supervisor rather than silently discarded.
  • Will it work on older Android devices?
    Yes. We target the devices your workforce actually carries and test on them. Our baseline is typically Android 9 on 2GB RAM.
