Apps Value is a Flutter app development company based in Krakow, Poland. We build production ready Flutter apps for startups and businesses across Europe and the United States, from a first version through App Store and Google Play launch and long term product development. One codebase, both platforms, scope and price agreed before development starts.
A senior Flutter team in Krakow that takes a product from discovery through to a published app on both stores. We work on fixed scope contracts, build new products and take over existing Flutter codebases, and you talk directly to the people building the app.
Production Flutter developers based in Krakow, working on real products rather than prototypes.
One Flutter codebase for both platforms, one release cycle, one set of business rules to keep correct.
Scope and price agreed before development starts, with the exclusions written down alongside the inclusions.
From product discovery through App Store and Google Play launch, then the work that follows the launch.
We build new Flutter products and take over applications where the previous team is gone.
Central European Time overlaps the full European working day and the American morning. Projects run in English.
First versions for startups, internal business applications that replace manual work, two sided marketplaces with payments and messaging, field service tools for technicians, booking and fitness products, and offline first apps that stay useful without a connection.
Launch a first version quickly and validate the product with real users before committing to the full build.
MVP development for startups OperationsCustom applications that replace manual workflows, paper and disconnected tools inside a company.
End to end app development Two sidedPlatforms with two user groups, profiles, booking, messaging and payments running between them.
Marketplace app development In the fieldMobile tools for technicians, contractors and distributed teams, connected to what the office needs to see.
Field service app development SchedulingScheduling, payments, profiles and the customer facing experience around them.
Fitness app development No connectionApplications that keep working when connectivity is unreliable or absent, then reconcile when it returns.
Offline first app developmentEach one is named with the problem it solved, not just the industry it sits in.
A fitness platform connecting people with personal trainers, covering scheduling, session swaps, chat and payments, with a web panel behind it.

Because for the products our clients build, one shared codebase means one team, one release cycle and one place where the business rules live. The interface behaves the same on both platforms, iteration is fast enough to change things during a review call, and long term maintenance costs less because there is one codebase to keep current instead of two.
That last point is the one that matters most after launch. Every operating system release, every store policy change and every dependency update has to be handled once rather than twice, and the two platforms cannot drift apart in behaviour because there is only one implementation of the rules.
Flutter is not right for every product, which is the next section. We recommend the technology based on the product, not on the technology we happen to sell. Where React Native is the better answer, we say so and build it in React Native instead.
When the product is built around platform specific functionality, when it needs a brand new native capability the moment it ships, when extreme native performance is the product itself, or when your existing team is a JavaScript team that will maintain the app afterwards. In those cases a different answer is cheaper for you.
Deep widget systems, complex background behaviour tied to one operating system, or hardware features that exist on one platform only. You end up writing native code anyway, on both sides.
When a platform ships something new, native access comes first and cross platform support follows. If your launch depends on being first, that gap matters.
Heavy real time graphics, low level media processing or anything where the last few milliseconds are the reason people use it.
If your engineers will maintain the app after handover and they work in React, React Native is the honest recommendation, not Flutter.
Three ways: a fixed price project for a defined product, dedicated Flutter developers who join your existing team, or a takeover of an app whose previous team is gone. Which one fits depends on whether you have a product owner and a delivery process already in place.
For a defined first version or a bounded product. You know the total before we start, and the scope list protects both sides.
See how we price projects Option twoFor ongoing product development inside your own setup. They work in your tools and on your schedule, and you meet them before anything is signed.
Hire Flutter developers Option threeFor products where the previous developer or team is gone. We start with an audit and tell you honestly whether continuing beats rebuilding.
App rescue and takeoverThe number is driven by the operation behind the app rather than by the number of screens. Payments, offline behaviour, integrations with existing systems and the number of user roles are what move it. Two apps that look identical can differ several times over in price for those reasons alone.
We quote a fixed price after scoping, so the figure you receive is tied to a written scope list with its exclusions named. That is the only kind of fixed price that is fair to both sides, because a fixed price on a vague scope means either you pay for our risk buffer or we quietly narrow what gets built.
Current figures and package shapes live on the pricing page. If you want the reasoning behind the ranges rather than a number, we break it down in our guides to mobile app development cost and MVP cost by app type.
Seven stages: discovery, scope, UX and UI design, Flutter development in sprints, QA, store release, and the maintenance that follows. Each stage has a written output and a condition that has to be met before it closes, which is what keeps a fixed price honest.
We map the business problem, the users and the integrations, and produce a product brief you confirm describes your business correctly.
We draw the line around version one, write down what is excluded, and price it. Nothing starts before both are signed.
Clickable prototypes you can test before any production code exists, designed for both platforms at once.
Two week sprints, each ending with a build you can install on your own device and a short written summary.
Automated tests plus verification on physical iOS and Android devices, with crash reporting connected before release.
Listings, privacy declarations, review notes and production builds, published on your own developer accounts.
Acceptance protocol, handover documentation, monitoring and the next iteration. On larger contracts a one year warranty starts here.
One person who can decide, availability during design and sprints, and early access to accounts and third party services.
It depends on the operation behind the app rather than on the screen count, so we quote after scoping and tie the figure to a written scope list. Current ranges are on the pricing page, and the reasoning behind them is in our cost guide.
Eight to twelve weeks from approved scope to a published first version is the normal range. Products with multiple user roles, real time features or enterprise integrations run longer. Every timeline we give comes with its conditions attached, because the largest variable is how fast decisions and access arrive from your side.
Yes, from one codebase, released to both stores from the same build pipeline. That is the main reason we default to Flutter: one implementation of the business rules, one release cycle, and no drift between the two platforms over time.
Yes, and it is a large part of what we do. A first version is scoped tightly around what has to be proven, with everything else written down as excluded so it can be added later as a decision rather than as an argument. More on MVP development for startups.
Yes. We start with a codebase audit and give you an honest answer on whether continuing is cheaper than rebuilding. Sometimes it is not, and we say so. Details on app rescue and takeover.
Yes, for teams that already have a product owner and a delivery process and need engineering capacity. They work in your tools, join your rituals and follow your schedule, and you meet the developer before anything is signed. More on hiring Flutter developers.
Yes, and it is a large share of our work. Central European Time overlaps the American morning, which is enough for same day decisions, and everything runs in English including documents you can circulate internally without translating them.
Krakow, Poland. We work with clients across Europe and the United States from there, and you talk directly to the people building the app rather than through an account layer.
Yes, when the scope is genuinely defined, because the scope list is what protects both sides. When the product is still finding its shape we say so and propose a different model, since a fixed price on a vague scope is dishonest to one of us.
Store policies and operating systems move every year whether or not you are building. We handle release management, crash monitoring, fixes and further development, and on larger contracts the software carries a one year warranty. More on maintenance and support.
Flutter when the interface carries the experience and both platforms must behave identically. React Native when your own engineers work in JavaScript, when you share logic with a web product, or when there is an existing React Native codebase to continue.
You do, from the start. The repository, the design files and the App Store and Google Play accounts are yours, and we publish under your accounts rather than ours, so nothing has to be migrated if you ever change supplier.
