Mobile app development

Take the product beyond the browser.

Build an iOS or Android app with the backend and release work it needs. We implement core journeys, connect services, and test behavior on the agreed devices.

Overview

Mobile app development turns product designs into working software for iOS or Android. The build includes the screens and device behavior, plus the APIs, authentication, and services the app needs. We account for interrupted sessions, connectivity changes, and platform-specific requirements in the scope. Testing and store submission preparation are part of the release plan. Our founders have delivered mobile product work, including the web and mobile rebuild of House of Manifestation.

What we work on

  • Choose the mobile architecture and define backend contracts
  • Build the agreed iOS and Android product journeys
  • Integrate authentication, payments, notifications, and device features as scoped
  • Test agreed devices and prepare builds and store submission materials

What you receive

  • Mobile application source code and platform build configuration
  • Backend integrations and documented API requirements
  • Device test results and release candidates
  • Submission preparation and maintenance handoff notes

What shapes the cost?

Platforms, device features, backend readiness, offline behavior, payments, and device coverage determine effort. Store and service accounts can carry separate charges.

What shapes the timeline?

The schedule includes product implementation and testing. Backend dependencies, developer-account setup, and store review affect when the app can reach users.

What to bring to the first conversation

Share designs, platform requirements, backend documentation, required device features, developer-account details, and any current mobile application code.

FAQ

Before we get started.

Should we build a native or cross-platform app?

The choice depends on device features, interaction requirements, performance needs, and the team that will maintain the product. We review those factors before recommending an approach. Sharing code can be useful, but some behavior still requires platform-specific work.

Can the app use our existing backend?

Yes, if the backend supports the mobile requirements. We review authentication, API behavior, data access, and any device-specific needs. Missing capabilities become part of the backend scope rather than an assumption left to the app build.

Do you handle App Store and Google Play submission?

Submission preparation and support can be included in the release scope. Your organization needs the appropriate developer accounts and approved product information. Store review is controlled by Apple and Google, so approval and timing cannot be guaranteed.
