FAQ
What does Zeise Digital do?
Zeise Digital develops modern, tailor-made and cross-platform applications for Android, iOS, and the web. We build complete solutions including backend integration, databases, analytics, and security features — from prototype to production.
Who are your typical clients?
We work with startups, small and mid-sized companies, educational institutions, and founders who want to bring a digital product to life. Whether it's an MVP or a large-scale app, we adapt to your business needs.
Do you build apps for both iOS and Android?
Yes. We develop native and cross-platform apps. Depending on the project requirements, we use technologies like Kotlin Multiplatform or native development for optimal performance and maintainability.
Can you also build web applications or browser-based dashboards?
Absolutely. Alongside mobile apps, we create web platforms, admin dashboards, portals, and custom digital tools with cloud-based backends.
Do you help with UI/UX design too?
Yes. We provide full UI/UX design services including wireframes, user journeys, clickable prototypes, and responsive layouts with a strong focus on usability.
How transparent is the development process?
We work with full transparency: regular progress updates, shared access to code repositories if desired, and clear cost structures. You always know what is being developed and why.
How much does an app cost?
The price depends on the scope and complexity of the features, integrations, and design. Smaller MVPs typically start with four-figure budgets, while full-scale products move into the five-figure range or beyond. We provide a clear estimate after an initial consultation.
Do you maintain apps after launch?
Yes. We offer ongoing maintenance, updates, feature expansions, performance improvements, and security monitoring after release.
Can you assist with publishing on the App Store and Google Play?
Yes. We take care of the entire publishing process including builds, certificates, store listing, screenshots, and updates.
How does the collaboration start?
It begins with a free consultation call where we discuss your idea, define the requirements, and evaluate technical feasibility. Based on this, we prepare a proposal and timeline.
