Apps Value is a mobile agency offering fixed price MVP app development for startups. We build iOS and Android MVPs in Flutter or React Native for founders who need to move fast without burning runway. Scoped upfront, no surprises.
30 minute call. No commitment. No sales pressure.
MVP app development is building the smallest version of a product that lets real users do the core thing it exists for, then shipping it to the App Store and Google Play so you learn from usage rather than from opinions.
How long it takes. A focused first version reaches both stores in 8 to 12 weeks. Marketplaces, booking systems and field tools run 12 to 22 weeks and are scoped in stages.
What moves the price. Not the number of screens. The number of user roles, whether money moves through the app, and the one integration the business model depends on. Bands for each shape are on our pricing page, and what a budget buys in general is in what an app development budget actually buys.

Most startups do not fail because of bad ideas. They fail because they build too much too slow and run out of runway before they learn anything. Focused MVP app development for startups fixes that: ship the core, learn from real users, then decide what to build next.
A focused MVP is in users' hands in 8 to 12 weeks. That is real feedback from real people, not assumptions. The faster you learn, the less you burn.
We scope everything upfront. You sign off on a fixed number before we write a single line of code. If scope stays the same, the price stays the same.
One codebase covers both platforms. No choosing between iOS and Android users, and no paying for two separate builds. Which framework fits is in Flutter or React Native.
MVPs that need to be thrown away and rebuilt from scratch are not MVPs, they are expensive experiments. We build foundations that hold when you grow.
Our MVP app development covers the full product, not just the app. Backend, infrastructure, App Store submission, everything.
iOS and Android from one codebase. Native performance, production ready code.
NestJS or Supabase depending on your needs. Authentication, database, business logic.
Email, social login, or phone auth. Secure from day one, not bolted on later.
Stripe or in app purchases if your MVP needs them, scoped and priced upfront. What the stores take is in in app purchase fees.
Web based dashboard so you can manage users and content without touching the database.
Full submission to App Store and Google Play. We handle certificates, provisioning, and review.
The hardest part of an MVP is not building it, it is deciding what not to build. Here is roughly where the line falls on a typical first release, using a two sided booking product as the example.
Every cut on the right hand side is reversible. None of them changes what you learn from the launch, which is the only thing version one is for.
Screens are not what moves the number. Roles, payments, and the one integration your model depends on are. Almost every first version falls into one of three shapes, and each shape has its own fixed price band on our pricing page.
One user role, one core flow, and the smallest question the market can answer.
Two roles, payments, and the one integration the business runs on. This is where most funded first versions land.
Marketplaces with money moving between users, booking systems with live calendars, and field tools that must work with no signal.
Every MVP is scoped before you pay anything, so the figure you approve is the figure you pay.
The hard part of a first version is not the engineering. It is agreeing what the launch is supposed to teach you, and then refusing to build anything that does not answer it.
Not mockups. Not prototypes. Production apps used by real people.
A two sided freelancer marketplace connecting clients with independent professionals. Real time job feeds, in app messaging, payment flows, and a web admin panel.
We scoped the full product, locked the price, and shipped it on both platforms without a single scope overrun. How we scope that shape is in marketplace app development.
A streetwear marketplace app for buying and selling limited edition drops. Product listings, user profiles, real time inventory, and a checkout flow built for speed.
Scoped tight, built fast, and delivered on a fixed price agreed before the build started.
The same first version rules apply to every startup, but the thing that decides the price is different for each product shape. Pick yours and read how we scope it.
Money moves between users, so the flow of every payment has to fit on one page before we quote. Reviews, disputes, and payouts can wait. Apple's business model review cannot.
Marketplace app developmentThe calendar edges decide the scope: recurring slots, time zones, and what happens to a booking cancelled mid payment. Version one is one provider type and one payment path.
Booking app developmentA technician, inspector, or driver who works with a phone in hand and often no signal. The first version is one job type, end to end, and the sync layer is scoped as its own line.
Field service app developmentOffline means three different things and the price depends on which one you need. If work has to happen with no network and arrive later without conflicts, say so on the first call.
Offline first app developmentWhere our founders are. Most of our MVP clients are in the US, and we work with live overlap on the East Coast afternoon from a team in Kraków, Poland. If you are building from the EU, the same team ships with EU data residency and invoices in euros, described on our app development for European companies page. If you want ongoing capacity instead of a defined build, that is nearshore Flutter developers in Poland.
Book an intro callThere are a lot of agencies that say they build MVPs. Here is what actually separates us as an MVP app development partner for startups.
We scope before we build. You approve a fixed number. If scope stays the same, the price stays the same. No hourly billing, no surprises.
No juniors billed as seniors. The people on your project are the people who built the portfolio you just saw, and you talk to them directly.
If your idea is too large for your budget, we will tell you before you pay us anything. We would rather scope down to a strong MVP than overpromise and underdeliver.
Two week sprints with live demos. You see working software at every milestone, not just a status update email.
Most of our clients are based in the US. EST and CST overlap, contracts in English, invoices in USD.
Mobile app, backend, database, cloud infrastructure, App Store submission. One agency, no coordination gaps.
Fixed price only works when both sides know what is being built. These are the situations where we will say so on the first call rather than take the project and disappoint you.
Exploratory work with a scope that changes every sprint is a real and legitimate way to build. It is just the opposite of a fixed price contract, and pretending otherwise ends badly for everyone.
We work remotely with live overlap on your working day. If your engagement genuinely requires people in the room, a local team is the better call.
Below a certain point the honest answer is not a cheaper app, it is a smaller question. We will tell you what would actually fit, or that nothing does yet.
There is always someone cheaper. If price is the only criterion, we are not going to win that comparison and we will not try to.
Four realistic ways to get a first version built. Each one is right for someone, and it is worth knowing which one you are actually choosing.
If you want ongoing engineering capacity rather than a defined build, that is a different engagement and we run it differently. You can hire dedicated Flutter developers from the same team on a monthly basis instead, or read how that works when you already have engineers in hiring for an existing team.
A straightforward process with no ambiguity at any stage. You know what is happening and why at all times.
You walk us through the product idea and your constraints. We ask the right questions and tell you what is realistic. No pitch, no pressure. If we are not the right fit, we will say so.
We break the full product down into a detailed spec, then give you a fixed price and timeline. You review everything and only move forward when you are comfortable. If you want that step on its own, it is our app discovery workshop.
We build in two week cycles. At the end of every sprint you get a live demo of working software. You stay informed without being pulled into day to day decisions. Where the weeks actually go is in our app development timeline.
We run full QA across real devices before submission. We handle the App Store and Google Play process, on accounts that stay in your company's name, and the full list of what that needs is in app publishing requirements. After launch, you own everything: code, credentials, infrastructure.
Fixed price delivery works because both sides hold up their end. This is the whole list, and none of it takes much of your week.
Someone who can approve scope and sign off on a sprint without waiting for a committee. This is the single biggest predictor of whether a project lands on time.
A sprint demo every two weeks and answers when a question blocks us. It is less about a fixed time commitment and more about being reachable when a decision is needed.
Store accounts and API credentials for anything we need to integrate with. Waiting on a third party login is the most common avoidable delay.
If there is an investor meeting or a launch date driving this, tell us on the first call. We will scope to the date rather than discover it in week six.
The questions serious buyers ask before a call, answered before you have to ask them.
You do, in full. Repositories, credentials, and infrastructure accounts are in your name from the start of the project rather than handed over at the end. We do not use proprietary frameworks that would tie the app to us.
Milestone payments tied to shipped work, not a lump sum upfront. You pay as things get delivered and demonstrated.
We price the addition separately and you decide whether to take it now, defer it, or trade it against something already in scope. Nothing gets added silently, and the agreed price does not move on its own.
That is what fixed price means. If we misjudged our own work, the cost of that sits with us, not with you. It is the whole reason the model changes the incentives, and you can read more about how fixed price delivery works.
With a signed acceptance protocol, so both sides agree the thing is finished rather than letting a project trail off. On larger contracts we back the software with a one year warranty.
We sign your NDA before the discovery call if you want one, and we will not name you as a client or show your product without written permission.
You can continue with us on a monthly basis, move to your own team with a documented handover, or simply stop. There is no lock in period and no retainer you have to accept to get the app built. Ongoing work is described under app maintenance services.
