Apps That Users Actually Keep — Not Just Download
We obsess over the session before the feature — what a user does in their first 90 seconds determines whether they ever come back.
Day 1
Retention is designed, not hoped for
React Native
One codebase, both platforms
App Store
Submission managed end-to-end
The app store is full of apps with 3-star ratings from users who downloaded once and deleted it. The apps that survive are the ones where the core interaction loop was stress-tested before the first line of Swift or Kotlin was written.
The graveyard of mobile apps is enormous. Most die not because the technology failed but because the UX was designed for the feature list, not the user. We prototype the core interaction — the screen a user sees 40 times a week — and test it with real users before we build anything around it.
We've built marketplace apps, field service tools, consumer fintech products, on-demand delivery platforms, and B2B workflow apps. The ones that succeeded shared a common trait: the core loop was clear, fast, and functional before we added the surrounding features.
Founders building a consumer app and needing the UX to earn retention from the first session
Enterprises replacing a field service process with a mobile workflow tool
Startups who've validated a web product and need a native mobile counterpart
Businesses whose React Native or Flutter app has performance issues and needs a rebuild
Product teams whose internal app has outgrown its original scope
What's different about how we build apps
Retention-First UX Design
The core interaction loop is wireframed, prototyped, and user-tested before development begins. We know which screen a user sees 40 times a week and we make sure it's frictionless.
React Native & Flutter
One codebase serving iOS and Android — with access to native device APIs, smooth animations, and performance that's indistinguishable from native for most use cases.
Offline-First Architecture
For apps used in low-connectivity environments — field service, logistics, healthcare — we build offline data sync from the architecture stage, not as a retrofit.
Push Notification Strategy
Not just technical implementation — a notification strategy that increases DAU without triggering the unsubscribe. Segmented, time-optimised, and tested against open rate benchmarks.
App Store Submission
App Store and Google Play submission managed end-to-end — metadata, screenshots, privacy policy, review responses, and expedited review requests when needed.
Post-Launch ASO & Analytics
App Store Optimisation, funnel analytics, crash reporting, and session recording set up at launch. You know what users actually do inside the app, not just who downloaded it.
The stack — and why
React Native for most cross-platform work — the ecosystem is mature, the developer pool is large, and performance is production-grade for most app categories. Flutter for projects requiring a truly custom UI. Native Swift/Kotlin for apps where platform-specific performance or system integration is non-negotiable.

From concept to live on the App Store
Core Loop Definition
Day 1–3We map the single most important user interaction — the thing someone does every session. Everything else is secondary. This session produces a prioritised feature list and a UX brief.
Prototype & User Test
Week 1–2A clickable Figma prototype of the core screens tested with real users before development begins. Cheap to iterate at this stage. Expensive to change after code is written.
Backend API Design
Week 2–3API contracts and data models defined before frontend development starts. Mobile apps are only as fast as their backend — we design for latency from the first endpoint.
Beta & App Store Launch
Final 2 weeksTestFlight/Firebase App Distribution beta, feedback integration, performance profiling on real devices, then App Store and Play Store submission.
Why most apps fail retention
We prototype before we build
A clickable prototype of your core screens, tested with real users, before any development budget is committed. The most expensive screen to change is the one that's already coded.
Backend performance is part of the mobile brief
Slow APIs kill mobile retention. We design the backend data model and API response shapes at the same time as the mobile screens — not after.
App Store rejection prevention
We've submitted enough apps to know every common rejection reason. Privacy policy requirements, data collection disclosures, in-app purchase rules — handled before first submission, not discovered in rejection notes.
We measure retention, not just downloads
Day 1, Day 7, and Day 30 retention rates are set up as primary metrics from launch. Downloads are a vanity metric. Retention is the health metric.
