Cross-platform from one codebase.

Mobile Apps

Custom Android & iOS apps — built in Flutter or React Native, shipped to the stores.

The problem

Where teams get stuck

Most mobile projects ship late, behind on the OS update cycle, and with a UX that screams 'web app inside a webview'. Native teams cost twice as much as you budgeted; cross-platform teams cut corners that show up in the App Store reviews.

Our approach

What we build

Production-grade Android and iOS apps from a single React Native or Flutter codebase, with native modules where they matter — camera, push, biometrics, payments. Shipped to both stores with CI, release management, and crash analytics wired in.

In depth

How mobile apps actually works at Codult

Mobile is the front door for most modern businesses, and a bad mobile experience compounds — your acquisition funnel, retention, and brand all bleed at the same rate. We build mobile apps for teams that need the polish of native without the cost of running two separate engineering org charts.

Our default stack is React Native with TypeScript, or Flutter when the app needs heavy custom UI or graphics. Either way, the foundation is shared business logic, typed APIs, and native bridges only where they earn their keep. The result is one codebase that ships to both stores with feature parity, half the timeline of dual-native, and a maintenance bill you can actually predict.

We treat the release pipeline as a first-class deliverable. EAS Build or Codemagic for CI, Fastlane for store submission, Sentry for crash reports, and over-the-air updates for non-binary changes. Your team can ship a bug fix in hours, not a two-week App Store review cycle.

Every app ships with the production essentials wired in: deep links, push notifications, secure storage, biometric auth, offline-first data sync, and accessibility passes for both platforms. After launch we hand over with docs, runbooks, and a 30-day pair-programming window; most clients keep us on a managed retainer for feature work and OS-version migrations.

FAQ

Common questions

Flutter or React Native — which one will you use?+

We pick per project. React Native fits teams already on React/TypeScript and apps that lean on standard widgets. Flutter wins when the UI is heavily custom, the app needs 60+ fps animations, or you want the same engine for embedded devices.

Do you submit to the App Store and Play Store for us?+

Yes — submission, signing, screenshots, store listings, and the first review cycle are part of the engagement. We hand over the publisher accounts so they're yours from day one.

How much does a custom mobile app cost?+

Most production-grade MVPs land between $25k and $80k depending on scope, integrations, and design depth. We share an indicative range after a 30-minute scoping call.

Can you integrate with our existing backend?+

Yes. REST, GraphQL, gRPC, or Supabase / Firebase — we adapt to your stack. If you don't have a backend yet, we build that too.

What about post-launch support?+

We hand over with docs and a 30-day pair-programming window. Optional managed retainers cover OS-version migrations, feature work, and on-call.
