Offline-first by default
Local persistence and conflict-aware sync, so a dropped connection never costs a user their work.
Build
Mobile apps people actually keep.
iOS and Android apps that feel native, work on bad connections, and survive the app store review process without drama.
Discuss this project
8–12 weeks to a store-ready first release
The short version
The bar for mobile is unforgiving. An app that stutters on a mid-range Android, loses a form on a lift ride, or asks for location on first launch gets deleted — and the one-star review stays up forever.
We build mobile the way the platforms intend: native gestures and transitions, offline-first data so the app works on the underground, and permission requests asked at the moment they make sense. Store submission, signing, and phased rollout are part of the job, not an afterthought.
Typically built with
React Native Swift Kotlin TypeScript SQLite Firebase Fastlane Sentry
What's included
How we approach mobile app development
Native feel, one codebase
Platform-correct navigation, gestures and haptics — with fully native modules where the shared layer isn't good enough.
Store submission handled
Signing, provisioning, review notes, privacy labels and phased rollout. We've been through the rejections so you don't have to.
Push, deep links and analytics
The plumbing that makes an app retainable, wired in properly rather than added in a rush before launch.
What you get
Delivered at the end
- iOS and Android apps published under your developer accounts
- Offline-capable data layer with sync

Questions
What clients ask about mobile app development
The things that come up most on the first call. Anything else, just ask — we answer straight.
-
Native or cross-platform?
Cross-platform unless the product needs otherwise — it's usually the same result for meaningfully less money. Heavy graphics, tight hardware integration, or demanding background work push us to native, and we'll say so before you commit.
-
Who owns the app store listings?
You do. Apps are published under your Apple and Google developer accounts from the first submission, so you're never locked to our accounts.
-
What happens when iOS or Android changes?
Both platforms ship breaking changes every year. If you're on a support plan we handle SDK upgrades and deprecations ahead of the deadline; if not, we'll flag what's coming at handover.
