We develop native iOS and Android apps as well as modern webapps focused on user experience, performance, and scalability.
Are you representing a company?
We ask because we tailor both pricing and the quote slightly differently for businesses and private customers. You can always skip ahead.
Native Apps
iOS & Android
Apps built specifically for each platform for the best user experience and access to all device features.
Push notifications
Keep your users engaged with targeted push messages directly to their phone.
Offline functionality
Your app works even without internet — data syncs automatically when the connection is restored.
App Store publishing
We handle the entire process of getting your app approved and published in the App Store and Google Play.
Webapps & PWA
Runs in browser
Webapps require no installation — your users access them directly via a URL on all devices.
Always up to date
No waiting for App Store approvals. Updates roll out instantly to all users.
Lower development cost
One codebase that works on all platforms — faster development and lower maintenance costs.
Progressive Web App (PWA)
Combine the best of web and native — install the app on the home screen with offline support and push notifications.
When to choose what?
Native app — when performance is critical
Choose native if your app requires access to camera, GPS, sensors, or complex graphics. Ideal for games, fitness apps, and apps with heavy data processing.
Webapp — when accessibility matters most
Choose webapp if your users need to access the system from any device without installation. Perfect for dashboards, booking systems, and internal tools.
PWA — the best of both worlds
Choose PWA if you want an app-like experience without the App Store. Good for e-commerce, news apps, and services with many users.
Both — for maximum reach
Many businesses combine a webapp for desktop users with a native app for mobile. We build both with a shared backend.
Apps that get used — not downloaded and forgotten
An app is only worth building if people use it every day
80% of all apps are deleted within 90 days of download. The only way to avoid that is to build something that solves a real problem — not something that's just 'nice to have'. We never start coding before we understand why users should open the app again tomorrow.
Native, cross-platform or webapp — we advise you
Most agencies are locked into one technology. We are not. We build:
- Native iOS (Swift) when performance and platform-specific features are critical
- Native Android (Kotlin) — especially for industrial apps and large audiences
- React Native when you want iOS + Android from one codebase — saves 30-40% development time
- PWA (Progressive Web App) when users don't need to go through the App Store — install from the browser, cheaper to launch
- Webapp — works on all devices via the browser, nothing to install
We recommend the right approach based on your budget, audience, and what the app needs to do.
What do you get with an app from Firma360?
- Strategy phase where we map user flows, retention mechanics, and success metrics
- Interactive prototype you can click through on a real device — before we code
- Backend + database + API — we build it all, not just the frontend
- App Store + Google Play publishing — we handle the review process, screenshots, descriptions
- TestFlight beta + crash tracking (Sentry) from day 1
- Push notifications (Firebase Cloud Messaging / APNs) ready to boost engagement
- Offline-first where it makes sense — the app works on the train too
- GDPR compliance + Danish hosting on request
- Ongoing bug-fix support per agreement
Price and timeline
Apps start from DKK 80,000 for a simple cross-platform app (one screen, basic features). A typical B2B app or B2C consumer app ranges from DKK 100,000 - 250,000. Complex apps with backend, AI features, or integration with many systems can cost DKK 250,000 - 500,000+. Timeline: typically 3-6 months from strategy to App Store live.

Frequently asked questions about app development
Native (Swift/Kotlin) gives the best performance and access to all platform features. Cross-platform (React Native) saves 30-40% development time if you want iOS + Android simultaneously and your app doesn't require heavy 3D, AR, or specialized hardware features. We recommend the right approach based on your situation.
