STACK / MOBILE APPS

Mobile Apps.
Cross-platform apps, offline-first, push & analytics.

We build mobile apps that feel fast, reliable, and intentional—on iOS and Android—without turning maintenance into a long-term burden.

ColibriCode is based in Denver, USA. We work with teams that already have strong backends in Drupal, Symfony/Laravel, Python, or Go and need mobile surfaces that plug in cleanly.

Focus

Cross-platform apps

React Native, shared logic, native where it matters.

Experience

Offline-first, push, analytics

Built for real users, not just POCs.

Backends

PHP, Python, Go

APIs that work well with mobile clients.

Location

Denver, USA

US-based, remote-first team.

WHY MOBILE APPS

Not just “an app”, but a product surface with a job to do.

We spend as much time deciding what belongs in the app as we do building it: the key flows, constraints, and events that matter when people are on the move or offline.

FOR USERS

Fast, predictable interactions.

We prioritize responsiveness, touch targets, and flows that can be completed in short bursts of attention.

  • Clear navigation for the 3–5 core jobs of the app.
  • Snappy lists, search, and detail views.
  • Meaningful errors, not generic “something went wrong”.

FOR ENGINEERING

Clean sync with your backend.

We collaborate with backend teams to design APIs that are realistic for mobile conditions: latency, offline, and versioning.

  • Efficient, cache-friendly endpoints for PHP, Python, or Go.
  • Stable contracts and clear deprecation paths.
  • Security posture aligned with your existing services.

FOR THE BUSINESS

Measurable impact, not vanity installs.

We tie features and metrics back to the goals that justified the app in the first place.

  • Activation, retention, and feature usage tracked by design.
  • Event models that match how you talk about your business.
  • Experiments and rollouts planned, not improvised.

HOW WE BUILD

Cross-platform apps, offline-first, push & analytics.

Cross-platform, with room for native

We start with shared code in React Native and add native bridges only where the product truly needs them.

  • Single codebase targeting iOS and Android where it makes sense.
  • Well-defined boundaries for any platform-specific components.
  • Navigation, state, and theming patterns that survive real growth.

Offline-first from day one

We design flows assuming that networks will be slow, flaky, or completely unavailable at times.

  • Local caching and queues for critical actions.
  • Conflict-aware sync strategies with your APIs.
  • Clear UI states for syncing, pending, and failed operations.

Push notifications done with restraint

Push should feel helpful, not spammy. We wire it to your real events and user preferences.

  • Event-driven triggers from your PHP, Python, or Go services.
  • Per-channel opt-in and granular user preferences.
  • Campaigns and journeys that you can adjust without full releases.

Analytics that actually answers questions

Instrumentation is tied to business goals: what users do, where they stall, and what features succeed.

  • Event models that match your domain, not just generic ‘screen_view’.
  • Funnels and cohorts that align with your roadmap.
  • Crash reporting and performance metrics wired into your ops stack.

COMMON PATTERNS

Where mobile makes the most sense for your stack.

Not every web feature belongs on mobile. We help you identify the high-leverage scenarios where an app changes the experience, not just the screen size.

External

Customer & partner apps

Portals for customers, vendors, or partners that extend your web experience into mobile without duplicating everything.

Internal

Operational & field tools

Apps for technicians, drivers, and field teams who work in low-connectivity environments and need reliable offline behavior.

SaaS

SaaS product companions

Mobile frontends for existing SaaS products, focused on the most critical on-the-go flows instead of shrinking your web UI.

Analytics

Exec & analytics views

Lightweight mobile dashboards that surface KPIs and alerts to decision-makers wherever they are.

BACKEND & INFRA

How mobile connects to your Drupal, PHP, Python, and Go systems.

We treat the app as part of your broader platform. That includes API design, auth, observability, and deployment pipelines that work with your existing stack.

APIS & DATA

  • Endpoints shaped for mobile: paginated, cacheable, and predictable, whether they’re served by Drupal, Symfony/Laravel, Python, or Go.
  • Authentication flows that balance security and usability: token-based, short sessions, and refresh strategies that fit your backend.
  • Offline-aware request queues with idempotent APIs, so retries don’t create duplicate work.

OPS & RELEASES

  • CI/CD pipelines for mobile that align with your existing Git and DevOps practices.
  • Logging, crash reporting, and performance metrics wired into your observability tools.
  • Feature flags and remote config so you can adjust behavior without a full release cycle when possible.

FAQ

Questions teams usually ask about mobile work.

Which mobile technologies do you typically use?

We primarily use React Native for cross-platform development, with native iOS/Android modules where performance or device capabilities require it. On the backend we usually integrate with Drupal, Symfony/Laravel, Python, or Go services via well-defined APIs.

Can you integrate with our existing PHP, Python, or Go backend?

Yes. We design API contracts that work well on mobile: predictable payloads, stable versions, and clear error semantics. We can help you adapt or extend your existing backend to better support offline sync, authentication, and push notifications.

Do you handle app store submissions and releases?

We can set up CI/CD pipelines, provisioning, and release strategies for both iOS and Android. That usually includes signing, build automation, environment configuration, and a release cadence that fits your team.

Can you improve an existing mobile app instead of rebuilding it?

Often, yes. We start by mapping the current architecture, identifying key issues—performance, instability, UX—and then propose a staged plan: refactors, new features, and only rewriting what truly blocks you.

TALK ABOUT YOUR MOBILE APP

Planning—or already running—a mobile app on top of your existing stack?

Share who the app is for, what they need to do, and which systems it connects to. We’ll respond with how we’d structure the app and where offline-first, push, and analytics can provide real value.

A short note about your users, platforms (iOS/Android), and backend stack (Drupal, PHP, Python, Go, etc.) is enough to start a concrete conversation.
