Cross-platform app development services for iOS and Android products

Your customers are split across iOS and Android. Covering both the old way means two codebases, two engineering teams, and two budgets for one product.

Cross-platform development removes that duplication. A single codebase ships to both app stores from one team, so you launch faster and reach the full audience for a fraction of the cost.

Altamira builds cross-platform apps that feel native on each device, hold up as usage grows, and stay easy to update after release.

Cross-platform mobile app development vs native development

Cross-platform is the right default for most products, but not every product. The choice comes down to how much you need platform-specific hardware, how fast you need to launch, and how you plan to maintain the app over time.

When cross-platform development is the right choice

Cross-platform fits when speed and budget matter and both audiences need the same core product.

  • Launch on iOS and Android at the same time from one budget
  • Ship an MVP fast and validate demand before heavy investment
  • Maintain one codebase instead of two separate teams
  • Keep branding and features identical on every device
  • Scale a standard app without duplicating engineering effort

When native development is still better

Native earns its higher cost when the app leans hard on a single platform or its hardware.

  • Heavy use of device hardware, such as advanced camera, AR, or sensor features
  • Peak performance for graphics-intensive apps or games
  • Deep platform-specific integrations that differ across iOS and Android
  • A product built for one platform only, with no plan for the other
Factor Cross-platform Native
Best use case MVPs, standard business and consumer apps, products for both platforms Hardware-heavy apps, games, single-platform products
Cost One codebase, lower total build cost Two codebases, higher total build cost
Time to market Faster, both platforms ship together Slower, each platform built separately
Maintenance One update path for both platforms Separate updates per platform

Why companies choose Altamira as a cross-platform app development company

Faster launch across platforms

One team ships iOS and Android together, so your product goes live on both stores in a single timeline instead of two.

Maintainable codebase

A single, well-structured codebase keeps future updates cheap and fast, so the app stays current without a rebuild every year.

Scalable mobile architecture

Architecture built for growth handles more users and more features on the same foundation, so scaling up does not mean starting over.

Results you can measure

Every engagement ties to outcomes you can track, from time-to-market to maintenance cost, so you see the return, not just the release.

Our cross-platform app development process

Structured design and delivery keeps your project on track and on budget from first call to launch.

01

Discovery

Clear project documentation comes first. Requirements, features, and success criteria get agreed up front, so the whole team works from the same plan.

02

Design

Designs map to your expectations and give users an intuitive flow through the app before a line of production code is written.

03

Development and QA testing

Delivery follows the requirements and deadlines your team commits to. Regular quality checks catch gaps and inefficiencies before they reach users.

04

Deployment and Maintenance

Support continues after launch. Clear communication and transparent processes keep you informed and confident as the app runs in production.

How we go from idea to app launch

A tight delivery path takes your product from concept to live app without stalls between stages.

01

Discovery and mapping

Goals, users, and core features get mapped into a clear scope, so the build starts with a plan the whole team agrees on.

02

Prototype in weeks

A working prototype lands in weeks, not months, so you test the idea with real users before committing the full budget.

03

Integration and delivery

The app connects to your data, cloud services, and third-party tools, then ships to both app stores as one coordinated release.

04

Scale and handoff

Post-launch, the app scales with demand and hands off cleanly to your team, with documentation and support that keep it running.

Cross-platform app development builds one app that runs on both iOS and Android from a single codebase. Instead of writing and maintaining two separate native apps, one team ships to both app stores, which lowers cost and speeds up launch.

Native development builds a separate app for each platform in each platform’s own language. Cross-platform builds once and deploys to both. Native gives maximum access to platform hardware at a higher cost. Cross-platform gives faster, cheaper delivery with a near-native feel for most use cases.

Cross-platform fits when you want to launch on both platforms at once, ship an MVP fast, or keep one codebase instead of two teams. It is the right default unless your app depends heavily on platform-specific hardware or peak graphics performance.

Timelines depend on scope, but a cross-platform build reaches launch faster than two native apps because both platforms share one codebase. A working prototype is often ready in weeks, with a full launch measured in months rather than the doubled effort native would require.

Performance comes from the right framework choice, clean architecture, and platform-specific tuning where it counts. Heavy screens and device features get optimized per platform, so the app stays fast and responsive on both iOS and Android.

Updates ship from one codebase to both platforms at the same time. Every user moves to the latest version together, which removes version drift and cuts the cost and complexity of maintaining two release paths.

Check technical expertise with cross-platform frameworks, a portfolio of shipped apps, client reviews, and a clear delivery process. Confirm the team can maintain and scale the app after launch, and that they can deliver inside your timeline and budget.
