Was kostet die Entwicklung einer App?

Die Preise sind individuell. Die Kosten hängen von Plattformen, Funktionen, Integrationen, Design und Zeitplan ab. Nach einem kurzen Briefing und einem kostenlosen Gespräch erhalten Sie eine schriftliche Schätzung.

Wie lange dauert die App-Entwicklung?

In der Regel: Analyse 1–3 Wochen, Design 2–5 Wochen, Entwicklung 8–16 Wochen für eine erste Version, Veröffentlichung 1–3 Wochen. Das sind Spannen, keine Garantien.

Sollten wir eine native oder eine plattformübergreifende App entwickeln?

Nativ (Swift, Kotlin) eignet sich für höchste Leistung und tiefen Gerätezugriff. Plattformübergreifend (React Native, Flutter) nutzt eine gemeinsame Codebasis und ist meist schneller in beiden Stores.

Wer arbeitet an unserem Projekt, und wie kommunizieren wir?

Projekte werden von UnFoldMart aus unseren internationalen Büros geleitet, mit einem kleinen festen Team. Gespräche führen wir per Video auf Deutsch, mit einer Demo nach jedem Sprint.

Wie gehen Sie mit Sicherheit und Datenschutz um?

Wir orientieren uns an OWASP MASVS, erheben nur die Daten, die die App braucht, und berücksichtigen die DSGVO von Anfang an. Sicherheitstests laufen vor dem Start.

Was passiert nach dem Start?

Apps brauchen Updates für neue iOS- und Android-Versionen. Den Support vereinbaren wir in Ihrem Angebot: Wartung und ein Plan für neue Versionen oder eine saubere Übergabe an Ihr Team.

Frequently asked questions

Before you book a call.

How much does it cost to build an app?

Pricing is custom. Cost depends on platforms, features, integrations, design and timeline. After a short brief and a free call, you get a written estimate.

How long does app development take?

Typically: discovery 1 to 3 weeks, design 2 to 5 weeks, build 8 to 16 weeks for a first version, release 1 to 3 weeks. Ranges, not guarantees.

Should we build a native or a cross-platform app?

Native (Swift, Kotlin) suits top performance and deep device features. Cross-platform (React Native, Flutter) shares one codebase and usually reaches both stores faster.

Who works on our project, and how do we communicate?

Projects are led by UnFoldMart from our international offices, with a small dedicated team. Calls are in English, with a demo after each sprint.

How do you handle security and data protection?

We follow OWASP MASVS, collect only the data the app needs and design for GDPR. Security testing runs before launch.

What happens after launch?

Apps need updates for new iOS and Android versions. Support is agreed in your quote: maintenance and a roadmap, or a clean handover to your team.
