Cross-platform apps

Cross-Platform App Development for iOS and Android

Netofficials delivers cross-platform app development services that put one app in front of iOS and Android users without funding two separate builds. You work with one cross-functional team, one named point of contact and a written discovery scope. Send a short brief and we will tell you whether cross-platform fits your product.

Delivery
One cross-functional team covering front-end, back-end, mobile, QA and DevOps builds your iOS and Android app from a single plan.
Contact
A named delivery lead owns day-to-day progress and keeps you updated, from the first brief to release.
Ownership
IP assignment is written into the contract before the build begins, so the app's source code is yours.
Reviews
Every sprint ends with a client-facing review, so you see the app take shape on both platforms.
What you get

One app for iOS and Android, scoped before it's built

A written scope for both platforms

We start with a written discovery scope that sets out the users, screens, device features and integrations your app needs on iOS and Android. You see what is in the first release, what waits, and where a platform-specific piece may be needed, before any build begins. That removes the guesswork that usually turns into rework later.

One team, one plan, two platforms

A single cross-functional team covering front-end, back-end, mobile, QA and DevOps builds your app from one plan. You are not coordinating separate iOS and Android projects or reconciling two sets of decisions. A technical architect is accountable for system design, technology selection and code quality standards.

Tested, reviewed and handed over

QA runs alongside development, and you review progress at the end of every sprint. At release, we hand over documentation and deployment access, and your IP assignment is already confirmed in the contract. If native would suit your product better, we will say so after scoping and can point you to our Swift option.

Who it suits

Built for products that need both platforms

  • A new app that must launch on iOS and Android together
  • An internal or customer tool still run on spreadsheets and email
  • An existing app that needs its second platform added

How the work flows

From written scope to a release on iOS and Android

  1. Discover

    We turn your brief into a written discovery scope covering users, core journeys and the first release for both iOS and Android. You review the platform-specific needs, such as device features and store requirements, that will shape the build.

    You receive
    • Written discovery scope
    • Open questions list
    • Initial estimate

    You agree the written scope and first-release boundaries

  2. Design

    Our designers and the technical architect plan one interface and one architecture that work on both platforms, and flag any screen where iOS or Android needs its own behaviour. You review the flows and the technology choices before any code is written.

    You receive
    • Mobile user flows
    • Interface designs
    • Architecture and stack notes

    You approve the designs and architecture before the build starts

  3. Build

    One cross-functional team builds the app in Agile sprints, with front-end, back-end, mobile and QA work moving together. Your named delivery lead keeps you informed, and you try working builds on both platforms as they develop.

    You receive
    • iOS and Android test builds
    • Sprint review notes
    • iOS and Android test results

    You review the app at the end of every sprint

  4. Validate

    QA tests the app against your agreed acceptance criteria on the iOS and Android devices you prioritise. You check the results and the open issues before the app is prepared for release.

    You receive
    • Acceptance checklist
    • Cross-device QA report
    • Issue log with status

    You sign off both builds against the agreed acceptance criteria

  5. Release

    We plan store submission, deployment and handover for iOS and Android, and you review the release plan with your delivery lead. Documentation and deployment access then move to your team.

    You receive
    • Store-ready release build
    • Handover documentation
    • Deployment access

    You confirm the handover is complete

Decisions before estimates

What shapes the scope of your cross-platform app

Platform behaviour and user roles

You tell us which journeys must feel native on iOS and Android, and who uses the app: customers, staff or admins. We map each role's access and what the app needs from the device, such as camera, push notifications or offline use. If a requirement fits native better, we say so after scoping and can point you to our Swift option.

Integrations and back-end data

Your app usually needs to connect to existing systems: an API, payments, a CRM or a database. We list those connections and the data behind them in the written discovery scope, so cost drivers show up before you commit. Your estimate rests on named assumptions rather than guesses.

Release, QA and support

One cross-functional team covers mobile, back-end, QA and DevOps, so testing on both platforms sits inside the plan. You decide which devices and OS versions to cover, who handles store submission and what support follows launch. We agree the communication window before work begins, and at release you receive documentation and deployment access.

Engagement models

Pick the engagement model that fits your app

Project delivery

Netofficials builds your iOS and Android app as a fixed-price project from a written discovery scope, which suits a product with clear first-release boundaries.

  • A written discovery scope that sets what the first iOS and Android release includes
  • Sprint-end reviews where you see the app running and steer the next priorities
  • Documentation and deployment access handed over when the app is released

Dedicated team

A dedicated India-based development team keeps building your cross-platform app after launch, which suits a product with a roadmap that will keep growing.

  • One cross-functional squad covering front-end, back-end, mobile, QA and DevOps behind a single point of contact
  • Sprint planning and backlog priorities set with your product owner, covering both iOS and Android
  • Source code and IP assigned to you under a contract confirmed before the build begins

Staff augmentation

Netofficials engineers join your in-house team to add mobile capacity, which suits companies that already run their own product process and need specific skills.

  • Cross-platform engineers added to your team for a specific gap, such as mobile front-end or QA
  • Engineers work in your repositories, ticketing and release process, with your tech lead setting priorities
  • Communication window, meeting schedule and update cadence agreed with you before work begins
Technology for your cross-platform app

Frameworks chosen after your scope is agreed

Netofficials confirms the cross-platform framework in your written discovery scope, after we have reviewed your features, device capabilities, existing systems and who will maintain the app once it is live. Our technical architect, who is accountable for technology selection and code quality standards, records the choice and the reasons for it. You see the decision before design and build begin, so you avoid rework from a framework picked too early. If the scope shows native iOS or Android would serve you better, we will say so.

Before you enquire

Cross-platform app questions, answered before you enquire

Is cross-platform the right choice for my app, or should it be native?

Cross-platform suits you when one app should reach both iOS and Android users from a single plan and team, rather than two separate builds. Native can fit better when the product depends heavily on platform-specific features or on one platform's behaviour. We assess this against your product during the written discovery scope. If native is the stronger route, we will say so and can point you to our Swift app development option.

What drives the cost and timeline of a cross-platform app?

Cost and timeline are driven by the number of workflows and user roles, the integrations and data the app must connect to, the design depth, and the testing and release needs on both platforms. We do not quote a figure before we understand those inputs. After the written discovery scope, you receive an estimate with assumptions and review milestones. Fixed-price project delivery, a dedicated team and staff augmentation are the three ways to engage.

Who owns the code, and how do we communicate across time zones?

You own the work: IP assignment is confirmed in the contract before the build begins, and documentation and deployment access are handed over at release. For communication, a named delivery lead owns day-to-day progress, and we agree the communication window, meeting schedule and update cadence with you before work starts. You also review the app at the end of every sprint. To begin, send a short brief.

Send your brief for an iOS and Android app

Tell us what the app must do, who will use it and which systems it needs to connect to. We review it, come back with questions and a proposed scope, and tell you plainly if native development would suit your product better. Your named delivery lead then runs the project, with the communication window agreed before work starts.
