Mobile Apps

We help you decide whether an app is the right move, then build one that holds up through OS updates, store reviews, and weak connections.

The problem

People download our app once and never come back, and each OS release seems to break something new.

Apps often get commissioned because a competitor has one. But nobody installs an app for something they do twice a year. Without repeat use, push notifications, device hardware, or offline work, a fast mobile web experience usually serves people better.

Launch also gets mistaken for the finish line. Store policies shift, operating systems change, and part of your audience never updates, so the backend keeps serving old versions.

Low retention tends to land on marketing's desk. Often the cause sits in the first session: a forced sign-up, an unexplained permission prompt, a slow cold start.

You may recognize this

  • Installs grow while active users stay flat.
  • Field staff go back to paper when signal drops.
  • You have no way to move users off a broken version.

How we work

  1. Justify the app

    We weigh usage frequency, required device features, and the maintenance budget you can commit. If a PWA does the job, we'll tell you.

  2. Pick the stack

    Swift and Kotlin, React Native, or Flutter: the call depends on device API needs, performance demands, and who will maintain the code.

  3. Design offline behavior

    We decide what lives on the device, how sync conflicts resolve, and how queued actions retry through idempotent calls. This shapes the data layer, so it comes early.

  4. Build the release pipeline

    Automated builds, TestFlight and Play internal tracks, staged rollouts, crash reporting, and a remote minimum-version check are ready before the first public release.

What we deliver

  • Platform decision record
  • iOS and Android apps
  • Offline and sync design
  • Versioned mobile API
  • Staged rollout pipeline
  • Store listings, privacy labels, and Data Safety form

How we measure

  • Crash-free sessions, an early read on stability before it reaches your store rating.
  • Retention by cohort, which shows habit in a way install counts can't.
  • Unsynced records, a direct measure of whether field teams can trust the data.

Elevator maintenance crews

Illustrative scenario: An elevator maintenance company has technicians working in basements with no signal, so forms get filled in back at the office. The app preloads work orders, captures photos and signatures offline, and syncs when a connection returns. A retry can't create a duplicate record.

Common questions

Native or cross-platform?

Cross-platform suits most business apps, and one codebase lowers upkeep. Go native when the app depends on heavy graphics, low-level Bluetooth, or deep platform features like widgets.

What if Apple or Google rejects the app?

Rejections are routine and usually fixable. Common causes are a missing in-app account deletion flow, vague permission text, and thin review notes, so we check store rules during design.

What should we budget after launch?

Plan for steady spend, since OS updates, SDK upgrades, and policy changes arrive whether you ship features or not. If that's unrealistic, consider a web-based route now.
