Mobile App Engineering
Apps that feel native.
On both stores.
iOS and Android, from one codebase or two — depending on what your app actually needs. Push, offline, deep links, store submissions, the lot. Designed for the device, not just resized for it.
The stack
Boring choices, executed well. Everything you’d pick if you were us.
Loads instantly.
Animates smoothly.
60fps animations, gesture-driven nav, haptics, native modals. Built so the seams between platforms and your app disappear.
- Native gesture handling + haptics
- Skeleton screens — no white flashes
- Offline-first where the use case demands
agent / accounts
React Native when right.
Swift / Kotlin when not.
We don't religious-war stacks. RN + Expo for most apps — fast to ship, easy to update. Native modules where the platform demands it (deep BLE, camera pipelines, AR).
- Expo EAS for OTA updates
- Native modules for platform-specific work
- Shared TypeScript types between app + backend

Push, sync, offline.
All boring solved.
Push notifications, deep links, background sync, offline cache, conflict resolution. The infrastructure that makes the app feel finished.
- Push (APNs + FCM) with delivery analytics
- Universal / app links + dynamic links
- Offline cache with conflict resolution

What ships
Everything below,
every project.
No upsells, no “that’s out of scope.” If it’s on this list, it’s included in the base price.
iOS + Android build
Both platforms, one or two codebases — picked for the app's actual needs.
Custom design
Designed mobile-first, not desktop-shrunk. Platform conventions respected.
Push + analytics
APNs + FCM, deep links, attribution, in-app analytics.
Backend + APIs
Auth, sync, push targeting — built or wired into your existing backend.
Offline mode
Cache + conflict resolution. App works on the subway.
Store submission
Listing copy, screenshots, privacy details, review notes — we handle the rejection-prone parts.
OTA updates
Push small fixes without a new app review (Expo EAS or CodePush).
Crash + perf monitoring
Sentry, native crash reporting, real-user performance metrics.
30-day support
Bug fixes free for 30 days. After that, retainer.
Mobile App
One flat price.
Scope written down.
For consumer or B2B mobile apps. Cross-platform by default, native where required.
