Native or cross-platform: decide from the requirements
Cross-platform development is often efficient when iOS and Android share the same product flows. Native development may be a better fit for deep platform features, demanding device integrations or separate platform roadmaps. The decision should follow the product requirements, not a developer's preferred framework.
Before hiring, document device permissions, offline behaviour, notifications, payments, analytics, backend APIs and supported operating-system versions. These details expose the skills and test effort the app actually needs.
From prototype to a production app
A production engagement includes more than screens: secure authentication, resilient API states, analytics, crash reporting, device testing, privacy disclosures and store-ready builds. We define acceptance criteria for the critical journeys and test them on representative devices.
The Apple and Google developer accounts should belong to your organisation. Store review support, release notes and handover documentation can be included so the app remains operable after launch.
How app developer onboarding works
For a new app, onboarding starts with a technical scope and a first releasable milestone. For an existing app, it starts with the repository, build pipeline, crash data and backlog. You meet the proposed developer and agree working hours, reviews and reporting before delivery begins.
If design, backend or QA is missing, those roles can be added around the app developer as a small product pod instead of leaving critical work unowned.

Frequently asked questions
- Can I hire an app developer for both Android and iOS?
- Yes. A cross-platform developer may cover both when the product requirements suit a shared codebase; native specialists can be used when platform-specific needs justify them.
- Can you take over an existing mobile app?
- Yes, after reviewing the repository, build process, backend dependencies, store access, crash reports and current backlog.
- Who owns the App Store and Play Console accounts?
- Your organisation should own both store accounts, signing access and production services. The developer is granted only the access needed to build and release.
- Do you support the app after launch?
- Ongoing maintenance can cover operating-system updates, crash fixes, security updates, analytics review and planned product iterations.
- What happens after I send a hiring enquiry?
- WASS reviews the outcome, stack, timing and team information you provide, then responds within two business days with clarifying questions or a recommended next step.
- Do I need a complete specification before contacting WASS?
- No. A clear business problem, current situation and first desired outcome are enough to start. Discovery can turn those inputs into a practical role profile or delivery scope.
- Is the initial strategy call free?
- Yes. You can reserve a free 30-minute strategy call after sending the form, or use the booking calendar directly.
