A mobile app is stronger when…
- People return frequently
- Notifications support a useful moment
- Device features or offline use matter
- Store distribution builds justified trust
New Zealand-based · iOS + Android
Build the right app. Then ship it properly.
Legion Algo Labs designs and develops mobile products across the customer app, backend, admin tools, integrations and release process—not just the screens people tap.
Bring an idea, an existing product or a stalled build. The first decision is whether a native mobile experience is actually the best commercial and technical route.
App or web app?
Start with the user behaviour, not the format.
Store presence can feel like the goal, but the better question is what the product must do repeatedly for a real user. Choosing the right surface early protects budget and makes the first release easier to learn from.
A web app is stronger when…
- Fast access by link matters
- The workflow is desktop-heavy
- You need to validate before store investment
- Search discovery is part of acquisition
Delivery capability
The pieces a production app actually needs.
iOS and Android
A coordinated cross-platform product where shared code is sensible, with platform-specific work where the user experience requires it.
Backend and admin
Authentication, databases, APIs, content management, reporting and the operational tools behind the customer-facing app.
Notifications and lifecycle
Permission-aware push notifications, preferences, onboarding and re-engagement flows tied to a useful product moment.
Store release
Build configuration, privacy inputs, listing readiness, review responses and release support for the agreed stores and testing tracks.
Payments and access
Subscriptions, one-off purchases, entitlements and account access designed around provider rules and clear failure handling.
Support after launch
Monitoring, fixes, dependency updates and staged improvements can continue under an agreed support arrangement.

Relevant proof
Release work is part of the product work.
Legion HQ combines accounts, structured content, subscriptions, notifications, databases, AI-assisted functionality and cross-platform entitlements. The iPhone app is publicly available; Android remains in Google Play testing, so no public Android launch is implied.
Delivery process
A release path with the hard decisions in order.
- 01
Choose the right surface
Decide whether the job needs a mobile app, a responsive web app or a coordinated product across both.
- 02
Define the useful first release
Map users, core workflows, data, integrations, constraints and the smallest release worth learning from.
- 03
Design and build
Create reviewable flows, application code, backend services and an admin experience that support the whole product.
- 04
Test the real journey
Check devices, permissions, poor-network behaviour, account states, payments, accessibility and critical workflows.
- 05
Release and learn
Prepare the agreed store or testing release, observe the product in use and prioritise evidence-led improvements.
Before discovery
App development FAQ
Good app decisions happen before code: product surface, ownership, store accounts, data, release risk and what a useful first version must prove.
Do I need a mobile app or would a web app be better?+
A mobile app is justified when the product benefits from device capabilities, frequent use, notifications, offline behaviour or store distribution. A responsive web app is often faster to validate and easier to access. Discovery should make this decision before technology is committed.
Can one app work on both iPhone and Android?+
Often, yes. Cross-platform development can share product logic and much of the interface, while still using platform-specific code where needed. The decision depends on device features, performance, interaction design and long-term maintenance—not a blanket preference.
Can you publish the app to the App Store and Google Play?+
Store and testing-track preparation can be included in scope. The client normally owns the developer accounts. Approval always remains with Apple or Google, so no developer can guarantee acceptance, but the build, privacy inputs and review responses can be prepared carefully.
Can the app include subscriptions, payments or user accounts?+
Yes. A project can include authentication, account recovery, subscriptions, one-off purchases, provider integrations and entitlement rules. Store policies, taxes, fees, data handling and failure states are considered during scope.
Can you take over an unfinished mobile app?+
Potentially. A technical audit should first establish the code quality, build health, account access, dependencies, backend state, store status and remaining product scope. That evidence determines whether repair or a staged rebuild is safer.
How much does app development cost in New Zealand?+
Cost depends on product depth, number of platforms, backend needs, integrations, content, payments and release risk. A focused validation build is materially different from a production platform. Legion scopes each project individually and may begin complex work with paid discovery before quoting delivery stages.
How long does it take to develop an app?+
A tightly focused first release may take weeks; a production product commonly requires staged work over several months. A responsible timeline follows discovery and accounts for client review, third-party integrations, testing and store review rather than promising a generic launch date.
Who maintains the app after it launches?+
Ongoing monitoring, operating-system compatibility, dependency updates, bug fixes and product improvements can be included in a support arrangement. Responsibilities, response expectations and recurring infrastructure costs are agreed in writing.
What should your app help someone do?
Start with that answer. Legion can help decide the right product surface, define a useful first release and build the system around it.
