Frequently asked questions

Do you work with clients outside the Netherlands?

Yes. We work fully online with clients worldwide, in English or Dutch. Prices are in euros.

Why are your prices lower than most agencies?

We build one app for iPhone and Android at once, reuse proven building blocks and automate a lot of the work. That saves hours, and you see the savings in the price.

Do I own the result?

Yes. After the final payment the code, design and content are yours. Apps are published on your own Apple and Google accounts.

How do I pay?

In three parts: 40% at the start, 40% when you approve the test version and 20% on delivery.

What does it cost after launch?

Apple charges $99 per year and Google $25 once. Hosting for small projects is often free to $25 per month. Maintenance is optional. All of this is listed in your quote.

Can I see something before I pay?

Yes. After a short intake by email we make a free clickable concept of 1–3 screens, so you can see we can really build it.
