Mobile app development for iOS and Android – from idea to the store

That depends on features, platforms and backend. We usually build native or cross-platform apps with user accounts, database and interfaces in the Professional package from €8,000. A simple web app as an entry point is possible in the Starter package from €2,500; extensive app platforms are quoted individually in the Enterprise package.

Depending on scope, a first version with the most important features can be in the store within a few months. Add to that the review by Apple and Google, which can bring follow-up questions. You will receive a reliable schedule after the initial consultation.

After the free initial consultation we define the feature scope of the first version, design a prototype and develop in stages with test builds on your device. After that we handle the store submission and continue to support the app after launch.

For many business apps, cross-platform with React Native or Flutter is more economical because one codebase serves both platforms. Native development with Swift and Kotlin pays off for very high performance requirements or special device features. We recommend the route after analyzing your requirements.

We recommend publishing the app through your company's own developer account with Apple and Google. That way the store listing, reviews and user base stay with you permanently. We help you set up the accounts.

Apple and Google release new operating system versions every year, which may require adaptations. We take care of updates, error analysis and new features – predictably under a maintenance contract if you wish.

You don't need a finished requirements specification. A short description of your target audience, the problem the app should solve and the features without which it makes no sense is helpful. Examples of apps you like help as well – we work out the rest together in the initial consultation and when defining the first version.

A freelancer can fit clearly scoped tasks or work as reinforcement for an existing team. An app, however, usually consists of design, app development, backend, store publishing and ongoing updates – here an agency covers more and doesn't depend on a single person. At Nano Concepts, design and development come from a single source together with LOMA DESIGN.

For apps aimed at customers, both platforms are usually important so you don't exclude anyone. For internal employee apps, one platform can be enough if everyone works with the same devices. With cross-platform development we serve iOS and Android from one codebase, so the second platform doesn't mean double the development effort.

Yes. Employee apps bundle things like jobs, photo documentation, time tracking or internal information and are connected to your existing systems. An example from our practice is an app for service technicians that also works without a network and syncs data later.

The biggest lever is a clearly limited feature scope for the first version: anything not strictly necessary follows later on the basis of real user data. Cross-platform development saves additional effort, and sometimes a progressive web app without a store is the more economical entry point. We advise you openly on this in the free initial consultation.
