Mobile App Development Company

Devs & Logics builds iOS and Android apps with React Native and Expo—shared codebase, native-quality UX, and backends that sync with your web SaaS or admin portal.

The problem we solve

Building separate native iOS and Android teams doubles cost and slows launches. Founders need one codebase, reliable releases, and mobile features that connect to the same backend as their web product.

What we deliver

We build iOS and Android apps for US product teams—UI/UX, API integration, App Store submission support, and release trains so mobile ships alongside your web SaaS.

  • iOS and Android from one codebase
  • React Native and Expo
  • Push notifications and offline support
  • App Store and Play Store submission support
  • Backend APIs and real-time features
  • Analytics and crash monitoring setup

Our process

  1. 1

    Product & platform plan

    iOS/Android feature parity, auth model, and offline requirements aligned with your API.

  2. 2

    Design & prototype

    Mobile-first flows, navigation patterns, and design system shared with web where possible.

  3. 3

    React Native build

    Expo or bare workflow, push notifications, analytics, and crash monitoring wired in.

  4. 4

    Store launch

    TestFlight and Play Console builds, store assets, and post-launch fix sprints.

Proof & outcomes

  • Single React Native codebase for iOS and Android
  • Shared APIs with Next.js SaaS products we build for the same clients
  • App Store submission support and OTA update workflows

Frequently asked questions

Do you build native iOS and Android apps or cross-platform?

We primarily use React Native for one codebase targeting both stores—faster and cheaper for startups. Native modules are added when a specific SDK requires it.

Can my mobile app share a backend with our web SaaS?

Yes. We design REST or GraphQL APIs so web and mobile clients use the same auth, billing, and data model—common in Devs & Logics MVP engagements.

Do you help with App Store and Google Play submission?

We prepare builds, signing, store listings, and review guidelines. Your Apple/Google accounts remain under your ownership.
