Overview
Flutter apps, in plain words
Flutter is Google's toolkit for building iOS and Android apps from one codebase, written in Dart. It draws every pixel itself, which keeps the app looking the same on both platforms. As a Flutter app development company, we use it when your product benefits from that.
Flutter and React Native are both solid. The better pick depends on your design, team and features, and we choose with you.
Your code, store accounts and signing keys are in your name either way.
Who it is for
- Products with a strongly branded interface that must look identical everywhere
- Apps heavy on animation, charts or custom-drawn screens
- Founders who want one team to build both platforms
- Businesses whose app differs between iOS and Android
What you get
- One Flutter codebase that builds the iOS and Android apps
- A custom interface that looks consistent across both platforms
- Store-ready builds for the App Store and Google Play
- Documentation, source code and accounts in your name

Signs you need it
Problems this work fixes
If one of these sounds familiar, you are in the right place.
- The design never survives developmentCustom designs often get simplified on the way to the phone. Flutter gives fine control over layout and motion, so what you approve is close to what you get.
- Android and iOS drift apartTwo separate apps diverge in features and looks over time. One codebase keeps them matched.
- Nobody on your team knows DartDart is less common than JavaScript, so hiring can worry you. We write clear, documented code and say honestly if React Native fits better.
- Choosing the framework by trendTeams often pick a framework because someone online recommended it. We pick on your features, design and people.
What is included
What we do, part by part
- 01
Framework decision
We compare Flutter and React Native against your needs and give reasons. Sometimes the answer is React Native.
- 02
Custom interface build
We build screens and transitions to match your design. Reusable components keep the look consistent.
- 03
Back-end and services
We build or connect sign-in, data, notifications and payments. Firebase and Supabase are among our options.
- 04
Testing on real phones
We test physical iOS and Android devices. We check smoothness on lower-end phones too.
- 05
Store submission
We prepare listings, screenshots and privacy answers. Then we submit to both stores through your accounts.
- 06
Handover and upkeep
You get documentation and 30 days of post-launch fixes. An optional plan covers Flutter and OS updates.

How it works
How the work runs
Decide on the framework
We look at your design and features and say whether Flutter fits. You get the reasoning, so the choice is yours.
Fix scope and price
We shape the plan around your budget. Once agreed, the price stays put.
Build interface and features
We work in weekly steps and you test a real build each time. Design questions are settled early.
Submit and support
We submit to both stores and handle review feedback. Store timing is theirs to decide.
Straight answer: Flutter is not automatically better or faster than React Native, and we will not pretend it is. If your team already writes JavaScript, React Native may serve you better. We cannot promise how long store review will take.

Quick answers
About cost and timing
The things people ask right after they see a price.
It depends on your features and how custom the interface is. One codebase generally costs less than two native apps. Payments, real-time data and an admin panel add to it. We scope on a call and fix the price in writing. Flexible on scope. Firm on price.
Our mobile projects typically run 8 to 16 weeks to store submission. Highly custom interfaces take longer than standard screens, which we price in. You get a dated plan after the first call. Store review adds time that Apple and Google control.
How we contract
Clear terms, before you spend anything
The commercial side in plain words. The full wording is in our terms, and your proposal sets the details.
- A written proposal comes firstScope, deliverables, milestones, price and timeline, in writing. Work starts when you accept it.
- The price does not moveOnce agreed, the number in the proposal is the number on the invoice. Changes to scope are quoted as a written change request and only built once you approve them.
- You pay by milestoneProjects are paid in milestones set in your proposal. No project is billed in full upfront. Invoices are payable within 14 days unless your agreement says otherwise.
- You own the workCode, designs and accounts are registered to your company from day one. We keep our own pre-existing tools and methods.
- No lock-inEither side can end a project with written notice, and you pay for the work done up to then. Retainers run month to month with 30 days written notice.
- 30 days of fixes after launchDefects in what we delivered are fixed for 30 days after launch. New features and third-party changes are quoted separately.
Flutter apps FAQ
Questions about flutter apps
The things people ask before they book. If yours is missing, ask us on a call or on WhatsApp.
Still have a question?
Thirty minutes with us usually answers everything, including whether we are the right fit.
Both build good apps. Flutter suits highly custom, animated interfaces that must match across platforms. React Native suits teams that know JavaScript and apps that should feel closer to each platform's own look. We recommend one after hearing your needs.
For most business apps, yes, and users will not notice a difference. Flutter compiles to native code and handles smooth animation well. Very demanding 3D or hardware-specific work can still favour fully native. We check your features before recommending it.
No one can promise that about any tool. Flutter is backed by Google and widely used, and your code stays yours either way. We keep the structure clean so parts could be rebuilt later if you ever needed to move.
Possibly. We review the current app and say whether a move is worth the cost. Sometimes a gradual rebuild works. Other times it is better to improve what you have. You get the honest answer before you commit to anything.
You do. Source code, Apple and Google developer accounts, signing keys and back-end accounts are registered to your business from the start. We work in them as collaborators, so you never have to ask us for access to your own app.
