What you get
Everything needed to get your app live, and nothing you don't need.
-
Design first
We design every screen together with you. You see exactly how your app looks and works before we start building.
-
One app, two platforms
Built with React Native and Expo: one codebase for iPhone and Android that feels like a real app on both.
-
Backend and accounts
Sign-in, data storage and push notifications if your app needs them, with Firebase as the backend.
-
Payments
Payments with iDEAL or card through Stripe, if your app needs them.
-
Testing on your own phone
A new test version every week, so you use the app before it goes live.
-
Launch in the stores
We publish your app in the App Store and Google Play: on your own developer accounts, or for free on Swivra's.
Is an app right for you?
- You want to be in the App Store and Google Play, not just on the web.
- Your users open your app often, for example to book, pay or keep track of something.
- You want to send notifications or use the phone's camera or location.
- You want to know upfront what it costs and when it's done.
Not sure you need an app? Sometimes a web app is enough. We'll tell you honestly.
Read about web appsWhat the price depends on
An app starts at €10,000. What your app costs mostly depends on these four things.
-
Screens and features
An app with a few screens is done sooner than a platform with chat, scheduling and profiles.
-
Sign-in and roles
Do users need to sign in, with different roles like customer and admin? That asks more of the backend.
-
Payments
One-off payments, subscriptions or paying out to others: each model works differently.
-
Integrations
Connecting to your accounting software, CRM or another service takes extra time.
After the intro call you get a quote with a fixed price. So you know where you stand before we start.

You don't have to build a complete app straight away. Start with a design, and pay for the build per demo.

App design
Your app's main screens, clickable on your own phone. So you know exactly what you'll get before you decide. If you don't like the design after two rounds of changes, you get your money back. Test it with users or show it to investors. If we build the app within six months, we deduct the design from the price.
-
Pay per demo
Apps, web apps and MVPs are paid per demo: after the demo of each part, you pay for that part. So you only pay for what you've seen. You may stop after any demo, and you take the code with you.
All prices exclude VAT.

What we build with
We build your app with React Native and Expo, in TypeScript. For the backend we use Firebase, or a custom API in Python with FastAPI or Django.
From first call to launch
You always know where your project stands.

Week 1
Intro call and quote
A free 30-minute video call about what you want built. Within a week you get a plan with a fixed price: what we build, in what order and when.
-
Before we build
Design first
We design every screen together with you. You see exactly what you'll get and change what isn't right yet. Only then do we start building.
-
Every week
Build and test
We show what's done. You test it on your own phone or in your browser, and steer where needed.

Launch and after
Launch and maintenance
We put your app in the App Store and Google Play, or your web app online. After that we keep everything up to date if you want, cancel any month.
Questions about app development
Question not listed? Email info@swivra.nl
Can I have just a design made first?
Yes. An app design starts at €1,500 and takes 1 to 2 weeks: your app's main screens, clickable on your own phone. So you know exactly what you'll get before you decide whether we build the app. If we build the app within six months, we deduct the design from the price.
Can I build my app with AI?
For a first version to show your idea, yes. With tools like Lovable, Bolt or Rork you have something on screen in minutes. An app in the App Store with logins, payments or customer data needs more: it has to pass Apple's review, be secure, comply with the GDPR and be maintained. Stuck with an app you made with AI? Then we finish it.
How long does it take to build an app?
Usually 6 to 12 weeks, depending on what the app needs to do. The quote comes with a week-by-week plan. For the App Store, allow a few days for Apple's review. The quote states the date your app goes live. If we go live late through our own fault, 2.5% of the price comes off for every week, up to 25%.
Why React Native and not two separate apps?
With React Native we build one app for iPhone and Android instead of two separate ones. That saves time and money, and for most apps you won't notice a difference from a native app. If your app needs something native code does better, we'll tell you upfront.
Do I need a developer account?
You don't have to. You can take your own accounts: Apple charges 99 dollars a year, Google a one-off 25 dollars. We'll help you set them up. You can also put your app on Swivra's account for free. The stores then show Swivra as the developer. If you want the app on your own account later, we move it over at no cost. That works if your app takes no payments and handles no health or financial data. Otherwise the app goes on your own account.
What if Apple rejects the app?
We build to Apple's and Google's guidelines, so review usually goes smoothly. If Apple still asks for changes, we handle them as part of the launch.
Can I add to the app later?
Yes. New features are a separate job with a fixed price. With maintenance from €150 a month, we keep the app up to date for new versions of iOS and Android.
