Treevoxa is a Flutter app development company for businesses that need an iOS and Android app from one code base, and the back end behind it. We help you choose between Flutter and React Native honestly, because the right answer depends on your app, not on our preference. Unlike a Flutter app development agency that only builds screens, we build the API and admin tools too.
When Flutter is the right choice
- Highly custom interfaces. Flutter draws every pixel itself, so a brand-heavy design looks identical on both platforms.
- Animation-rich apps where smooth motion matters more than native look and feel.
- An existing Flutter code base or a team that already knows Dart.
- Several targets from one code base, such as phone, tablet and desktop.
When the app shares a lot with a React web app, or your team writes JavaScript, React Native usually wins. Our own products ship React Native apps, and we will tell you if that is the better route for you.
Flutter app development services
- New iOS and Android apps from a clickable prototype to store release.
- Back ends and admin tools for the app: APIs, roles, dashboards and notifications. See API development services.
- Integrations with payment providers, maps, cameras, files and push notifications.
- Store releases under your own developer accounts.
- Audits of existing Flutter apps before we agree to take them over.
What we bring from our own products
Our HR, real estate and pharmacy products each serve web and mobile users from one API, with the same logins, permissions and audit trail. Whatever framework draws the screens, that back-end pattern is what keeps a business app reliable: one source of truth, documented endpoints, tokens in secure storage, and actions queued and synced when a connection drops. See MatrixHR for an app built this way.
How a Flutter project runs
- Discovery: users, devices, connection, and what they do today instead.
- Stack recommendation: Flutter or React Native, with the reasons in writing.
- Prototype of the key screens, tested with real users.
- Written scope and quote.
- Build in short cycles, with test builds on your phone every one or two weeks.
- Store release and support.

Engagement models for Flutter work
- Fixed scope for a first version, paid per milestone.
- Dedicated developer for an app that keeps growing. See hire dedicated developers.
What a Flutter app costs
An app's cost depends on screens, offline needs, device features, integrations and whether the back end exists. Our custom software development cost guide explains how quotes are built. We quote in US dollars, in writing.
Who Flutter app development is for
- Brands with a distinctive design that must look identical on every phone.
- Teams with Dart experience or an existing Flutter code base.
- Products targeting phones, tablets and desktop from one code base.
Questions to settle before an app project
- Who uses the app, and how often? Daily users justify an app; occasional users may be better served by a mobile website.
- Does it need to work offline? Offline support changes the architecture and the price.
- Which device features does it use? Camera, location, files, payments and notifications each add work.
- Does a back end exist? An app on an existing API is a much smaller project.
- Who will maintain it? Choose a framework your future team can support.
Our guide to React Native app development cost works through these questions with a worked estimate; the hours are broadly similar for Flutter.
What to send us for a Flutter app quote
Who will use the app, the five most important things they will do in it, any designs you have, and the systems it must connect to.
Questions to ask before you hire a Flutter team
- Can we install an app you built and use it?
- Why Flutter rather than React Native for our app?
- How will offline use and syncing work?
- Who publishes the app, and under whose developer accounts?
- Who will maintain the app after launch, and at what cost?
Ask every bidder the same questions, in writing, and compare the answers before you compare the prices.
