What the work covers
Mobile app development, explained in working parts.
Each area below describes a type of work Mentarich can deliver. Your project scope defines what we actually do.
Work area 01
Discovery and MVP scoping
A mobile app succeeds when the first release solves one clear problem well. We evaluate the workflow, identify the core user journey, and define the smallest release scope that can be tested with real users.
- User problem and workflow evaluation before writing code
- MVP feature prioritization focused on essential user tasks
- Platform selection based on audience, device needs, and budget
- Technical risk assessment for third party services and APIs
- A written project scope with agreed milestones and responsibilities

- Secure local storage using Android Keystore and EncryptedSharedPreferences
- Background task handling following Android battery and lifecycle rules
- Compatibility testing across multiple Android API levels
Work area 05
Cross platform mobile development
Cross platform engineering allows one shared codebase to power both iOS and Android apps. We use React Native and Flutter to deliver near native performance while keeping maintenance and updates unified.
- Shared logic and UI components across iOS and Android
- Native bridges and modules for platform specific capabilities
- Fast iteration cycles with unified bug fixes and release updates
- Code organization structured for long term maintenance
- Consistent user experience across both operating systems
Work area 06
Authentication and user management
User onboarding must be frictionless and secure. We implement modern authentication flows, session management, and role based permissions that protect customer data from the start.
- Email, passwordless magic links, and social login integrations
- Biometric login with Face ID, Touch ID, and Android Biometrics
- Secure token refresh and encrypted session storage on device
- User profile management, password resets, and account deletion flows
- Privacy compliance including data export and privacy policy links
Work area 07
Backend APIs and database architecture
A mobile app is only as dependable as the backend powering it. We design resilient REST and GraphQL APIs, real time subscriptions, and database models that keep data synchronized and fast.
- API design and integration with REST, GraphQL, or RPC endpoints
- Database schema design and queries optimized for mobile usage
- Offline caching and optimistic UI updates for intermittent connections
- Rate limiting, request validation, and server error handling
- Secure communication over HTTPS with data encryption in transit
Work area 08
Push notifications and messaging
Notifications keep users informed when relevant events occur. We implement targeted push notifications, local reminders, and in app message centers that respect user attention and platform permissions.

Timeline
How the work is paced.
A focused MVP application typically takes six to twelve weeks from discovery to test build delivery, depending on feature complexity and API readiness. Complex platforms with extensive third party integrations or custom hardware needs are scoped in reviewable milestones with agreed delivery schedules.
Limitations
What we do not promise.
We build and test the agreed scope against platform standards, but final approval on the Apple App Store or Google Play Store is decided solely by Apple and Google review teams. We do not guarantee store approval timelines, downloads, active user counts, or commercial revenue, as these depend on market demand, marketing, and external policies.

FAQs
Useful answers before we start.
Should we choose native or cross platform development?
Cross platform frameworks like React Native or Flutter are usually the fastest and most cost effective choice because one codebase serves both iOS and Android. If your app requires heavy background processing, custom Bluetooth hardware communication, or advanced AR features, native Swift and Kotlin may be preferable. We review your exact requirements before recommending an architecture.
How do you approach building an MVP first?
We prioritize the core user workflow that proves value to early customers while deferring nonessential features. This keeps initial development focused, reduces time to test builds, and creates a solid technical foundation that can be expanded later.
Do you handle Apple App Store and Google Play submissions?
Yes. We configure developer accounts, prepare certificates, create store metadata assets, manage privacy declarations, and upload builds to TestFlight and Google Play Internal Testing. Final approval is determined by Apple and Google review guidelines.
Can the mobile app connect to our existing backend and database?
Yes. We integrate with existing REST, GraphQL, or custom APIs. If backend endpoints do not exist yet, we can design and build the supporting API layer and database models.
What happens after the app is launched?
We offer agreed maintenance support to monitor crashes, handle annual iOS and Android SDK version updates, resolve bugs, and implement new feature requests as your user base grows.
