One platform
Android or iOS. The second platform has its own adaptation and testing, at 1,500 EUR.
Mobile apps
An app people open again.
An app with too many features at launch costs a lot, takes long and hides the very action users installed it for. You get an app built around one essential journey, with a clearly defined backend, tested on real devices and ready for publishing.
What you get
Mobile apps
- One platform
- Up to 5 screens
- Authentication
- Basic backend

- Special infrastructure is confirmed before ordering.

Phone features

Do you develop native or cross-platform?
We choose the technology based on the features needed. Often a cross-platform base with interfaces adapted to each platform is enough and lowers the cost of the second platform. We don't push native development when it isn't needed.
What does the basic backend include?
User accounts and app data, managed on the server, for the main flow. Extensions such as reports or a full web admin panel are separate modules.
I already have a backend. Do I pay for it again?
No. The “App on an existing backend” option costs 3,800 EUR and includes integration and testing with your API. We need the API documentation to confirm the estimate.
Who pays for the app store accounts?
You, directly to Apple and Google. The Apple account has an annual fee and the Google one a one-time fee; the amounts are set by them. We recommend the accounts be in your company's name.
Do you guarantee publishing on the App Store and Google Play?
No. We prepare the app according to the stores' published rules and assist you during review, but the decision is theirs. If they request changes, we handle them within the agreed deliverables.
Do push notifications work on both platforms?
Yes. They are implemented once, shared, at 180 EUR. The user has to accept notifications on their phone.
Can the app work without internet?
Yes, through offline mode: essential data stays available and syncs later. It is a complex feature, at 500 EUR and 15 hours.
How long does an app take?
The base package has an estimated effort of 130 hours. At 4 productive hours per day, the calendar timeline exceeds one month, and app store review is not included in this calculation.
How do I pay?
30% deposit and 70% at handover, or six equal monthly instalments with the total increased by 30%, which include basic maintenance during the instalment period.
