Native Mobile App Development.
We design and build iOS and Android apps — native where the platform demands it, cross-platform where it doesn't. Every app ships with crash reporting, analytics, and a release process the team can run without us. Stack choice is a conversation about audience, budget, and who maintains the app in year two, not a default.

whether an app ships.
Most app projects don't fail at development — they fail at a handful of decisions made before a single screen is designed. These are the ones we work through with you first.
Platform: iOS, Android, or both
Which platform your users actually live on beats which platform is easier to build for. If 85% of your audience is on Android, an iOS-first launch is vanity. We look at your analytics, your market, and your budget before recommending single-platform, dual-platform, or cross-platform.
Native or cross-platform
Flutter and React Native cover most app shapes at a fraction of the build cost. Native (Swift / Kotlin) earns its place when the app leans heavily on platform-specific hardware, camera pipelines, or OS-level integrations. We'll tell you which bucket you're in, honestly.
Offline-first by default
Phones lose signal. Apps that break when the network does — or lose the user's draft, or silently fail to sync — get uninstalled. We design data flow assuming the connection is unreliable, and the app still feels instant.
Native integrations that matter
Push notifications, deep links, biometrics, camera, location, payments, widgets. We wire the ones your product actually uses, test them on real devices, and document the permissions story for store review.
Release cadence and CI
Fastlane or EAS for automated builds, a staging track on both stores, and a release checklist you can run in an afternoon. Pushing a hotfix should not require us; we leave the pipeline in your team's hands.
Year-two maintenance
The hard part of an app isn't launch — it's the OS update that breaks your camera code six months later. We write the codebase and the docs so the next engineer (yours or ours) can pick it up without a month of archaeology.
A short list of
real things.
Not deliverables in the consultant sense. Actual files, pages, docs, access. Listed here so there's no surprise.
- 01Design for every screen across the platforms the app ships on, with interaction states
- 02Native or cross-platform build tested on real iOS and Android hardware, not just simulators
- 03Push notifications, deep links, and authentication wired and verified end-to-end
- 04Crash reporting (Crashlytics / Sentry) and product analytics (Mixpanel / Amplitude / GA4) instrumented
- 05CI pipeline for staging and production builds, plus a written release runbook
- 06App Store and Google Play listings: screenshots, descriptions, privacy manifest, data-safety form
- 07Submission, first-pass review response, and a store-approved v1.0 live in your account
- 08Handover documentation: architecture notes, env config, release steps, known issues
How we work, start to finish.
- 01Scoping and platform call
We look at your audience data, the features you're planning, and your budget. Output: a one-page recommendation on iOS / Android / both, native vs cross-platform, and a realistic milestone plan. No design work begins until this is signed off.
- 02Design
Figma design for every screen, across both platforms where relevant. Interaction states, empty states, error states, offline states — not just the happy path. Reviewed on real devices with screen-mirroring, not just Figma previews.
- 03Build
Development against the design, with staging builds on TestFlight and Google Play internal testing from week two onward. You install the app on your phone throughout the build — feedback happens against the real thing, not screenshots.
- 04Store submission and launch
We handle store listings, privacy manifests, data-safety forms, and first-pass review responses. Once the app is approved we set up crash and analytics dashboards, run a two-week monitoring window, and hand over the release pipeline to your team.
The baseline we ship to.
Not a premium tier. Every app we deliver meets these four baselines on day one, whether it's a two-screen utility or a full marketplace.
