Brief
You describe the users, the job to be done, current tools and any hard date or constraint. A page is enough.

Mobile applications with the backend already thought through
A mobile app is not a screen export. It is a product with sessions, offline behaviour, notifications, store review, and a server that must stay in step. Hirvex Technologies builds iOS and Android apps—often with Flutter or React Native—and the APIs, admin panels and release process around them.
Who this is for. Operators who need staff apps, customer apps or both, and who do not want a pretty client with an unfinished backend.
Problems we typically meet
These are the patterns that show up before a useful first release—not abstract “digital transformation” language.
- The app was designed as screens, with APIs invented at the end.
- A hybrid experiment cannot meet store, performance or offline needs.
- Push notifications, versioning and forced updates were never planned.
- Operations still manage the same work in a desktop tool the app does not reflect.
How we approach the work
We define the jobs the app must do in the field, then the data it must read and write. Cross-platform frameworks are used when they reduce cost without fighting the platform. Native modules are introduced only where they are justified. Store listings, privacy disclosures and a rollout plan are part of delivery, not a week-before panic.
What a serious first release can include
Scope is confirmed in discovery. This is the shape of work we are equipped to deliver—not a menu you must buy in full.
- Flutter and React Native product apps
- Native iOS or Android work where the product requires it
- Authentication, roles and device-level session handling
- Offline-tolerant flows for field and retail teams
- Push notifications and in-app messaging
- Companion admin web apps and APIs
- TestFlight / Play Console release support
What we need from you
A useful brief is better than a long one. If you can answer most of the following, we can propose a first slice instead of a theatre estimate.
- Who will use this, and what must they finish in a session?
- Which systems must stay (accounting, payments, identity, a shop)?
- What is already live that we should not break?
- Any hosting region, language or compliance rule that is non-negotiable?
- The date that actually matters—and why.
How an engagement runs
Four steps. No mystery bench.
Scope
We reply with clarifying questions and a first-release outline: modules, roles, integrations and what “done” means.
Build
Named engineers work in visible increments, with staging you can click and a weekly written status.
Run
Launch, handover and a support path. The system is yours to operate—not a black box we disappear from.
Questions we are asked
Flutter or React Native?
Both are in our delivery stack. Flutter is often efficient for new products with custom UI. React Native can be a better fit when the web product is already React and the team wants shared thinking. We pick after we see the product, not before.
Do you publish to the App Store and Google Play?
We prepare builds, listings, privacy questionnaires and review responses. The developer accounts remain yours unless you explicitly ask us to operate them under a written arrangement.
Can the app work without constant connectivity?
When the job requires it, yes. We design sync, conflict handling and honest UI for “you are offline” instead of failing silently.
Will you only build the app and leave the API to us?
We can. We can also own both. Split ownership only works when contracts, environments and API versioning are explicit.
