Flutter app development

Flutter app development, from first build to ongoing releases

Tg Apps builds and evolves Flutter applications across Android, iOS, and web. We can own the app and its connected backend work, take over an existing codebase, or deliver one product area alongside your team.

New project inquiries: we respond quickly.

Build a new Flutter product with the APIs and workflows it needs.

Take over and move an existing Flutter app forward.

Coordinate backend integrations, App Store and Play Store releases, and ongoing updates.

Flutter delivery in practice

DocVita: ongoing app and backend development

Tg Apps develops and continuously evolves DocVita's Flutter applications and backend services. The public case shows delivery across patient, professional, and company workflows, including integrations and release work.

See the DocVita case

The work behind the app

A public Flutter and backend case with clearly described Tg Apps responsibilities.
Coordinated application, API, data, and release decisions as product rules change.
Continuous delivery that covers new workflows and the care an existing product needs.

What we can own

Flutter application flows for Android and iOS, with web delivery when the product calls for it.
Backend APIs, authentication, payments, notifications, files, analytics, and integrations.
Builds, store submissions, staged releases, monitoring, fixes, and handoff documentation.

Where to start

A new product needs Flutter development tied to real backend and release work.
An existing app needs new features, integrations, or a dependable release cadence.
A team needs us to own the app or one critical product area alongside its developers.

How we help

Build the app and the system it depends on

A useful Flutter product needs its mobile experience, data rules, integrations, and release path to move together.

01
Define the first working delivery and the product flows that matter most.
02
Develop Flutter interfaces and coordinate the API and backend changes behind them.
03
Prepare Android, iOS, and applicable web releases with the client-owned accounts and environments.

How we help

Move an existing Flutter app forward

We can join a product already in use or assess a codebase that another team started.

01
Review the build, dependencies, app architecture, backend contracts, and store status before defining the first step.
02
Add features, repair blockers, and preserve useful work when taking over an existing app.
03
For a stalled project with an unclear release path, start with the dedicated app rescue approach.

How we help

Keep releases moving after launch

Ongoing Flutter work can cover product improvements and the technical care needed to keep an app usable.

01
Update dependencies and platform compatibility as Android, iOS, and connected services change.
02
Handle bugs, integrations, performance work, store requirements, and planned releases.
03
Failures that affect product operation receive priority attention in every plan. We investigate and work on the fix without waiting for the next scheduled delivery cycle.

FAQ

Frequently asked questions

Can you take over a Flutter app built by another team?

Yes. We first review the codebase, build process, access, backend dependencies, and release status, then agree on a useful first delivery.

Do you also work on the backend?

Yes. Tg Apps can deliver the APIs, data flows, authentication, and integrations connected to the Flutter app, with responsibilities defined for each project.

Can you maintain the app after launch?

Yes. Every plan can cover updates, fixes, integrations and releases. Planned work follows the selected cadence, while failures affecting product operation receive priority attention without waiting for the next delivery cycle.

Monthly software plans

Same engineering capabilities, different ways to work together

Every plan can build, launch, evolve and support your products across mobile, web, backend, CRM, internal tools and AI integrations. Daily asynchronous group communication is included, with no added charge for questions, requests, updates or feedback. Choose the delivery rhythm, level of live coordination and flexibility to reorganize work.

Steady: USD 1,500/mo. Planned two-week delivery cycles and meetings, with autonomy to execute between reviews. Product size or technical complexity does not restrict the service range.
Growth: USD 2,000/mo. Weekly meetings and delivery cycles, with closer collaboration and intelligent allocation across the agreed priorities.
Embedded: from USD 3,500/mo. Daily meetings when needed, continuous delivery and closely managed execution. Team size, working hours and additional coverage can adapt to your operation, with capacity and monthly pricing agreed together.
Failures that affect product operation receive priority attention in every plan. We investigate and work on the fix without waiting for the next scheduled delivery cycle.
The plans are not fixed hour banks. Before kickoff, we align the first milestone, active workstreams, response rhythm, and what can realistically move inside the selected plan.

Shared capacity

One ongoing engagement can cover development, improvements and production support across multiple products, including integrated systems and global apps. Adding another product does not create an extra fee by itself: the products share the contracted capacity, with agreed priorities and workstreams.

Delivery cycles

Each cycle advances the agreed work. Larger milestones may span several cycles, and production deployments follow the agreed release plan.

Clear first milestone, month-to-month continuation, and a fixed plan rate while the engagement remains active. USD prices are public references. The actual monthly amount is fixed before kickoff in the billing currency agreed with the client.
