iOS app development

Nexus Apps designs and develops iOS apps for companies and founders. Based in Berlin, we work in English with teams across Europe and worldwide, from an initial product idea to App Store release and further development.

Decisions that
shape the scope

Shape the iPhone experience

We start with the people who will use the app, the problem it solves and the tasks that matter in the first release. Camera features, on-device processing and existing systems help shape the technical scope.

Plan the complete product

An iOS app may also need accounts, a backend or connections to other services. We discuss those dependencies, access and release requirements before agreeing on the work.

Who it is for

Is this right
for your project?

For companies building a customer-facing iPhone app, founders validating a mobile product, and teams planning the next release of an existing iOS app.

Product definition

User journeys, priorities and a scope for the agreed release.

iOS interface design

Screens and interactions designed around the product and its users.

Development and integration

iOS app implementation and the agreed backend or service connections.

Testing and release

Testing key journeys, preparing the release and coordinating App Store submission.

Agree on the scope
before development.

We start with your users and the problem to solve. Together we agree on the deliverables, release plan and review points.

Features, integrations and platform requirements shape the estimate. We discuss cost and timing before the build begins.

Working together

Based in Berlin.
Working beyond it.

We work with companies in Berlin, across Europe and worldwide. Projects can be discussed remotely, with in-person meetings in Berlin or elsewhere in Europe by arrangement.

We agree on the scope, review points and ways of working around the needs of each project.

Built and operated by Nexus

Apps we build and operate

Our published iOS products are built and operated by Nexus Apps. Photo CamAI uses on-device photo analysis, while Retro Cam Neo previews camera looks in real time. Visual LabX combines editing and retouching in one app. These are in-house products, not commissioned client projects.

Visual LabX is rated 4.8 out of 5 from more than 600 ratings on the U.S. App Store, as of November 13, 2026. These ratings reflect our own app, not client projects.

Before we start

Questions about the work

Can you work on an existing iOS app?
We can discuss an existing app after reviewing its source code, dependencies, design and release setup. The review helps determine what can be reused and what work is needed.
Can the app connect to our existing systems?
We assess the available APIs, access and data flows before agreeing on integrations and their scope.
Can you help with App Store submission?
Yes. For an agreed release, we can help prepare and coordinate App Store submission. Approval remains subject to Apple’s review.
What happens after the app launches?
We can agree on a separate engagement for maintenance, compatibility updates, fixes and further features, with responsibilities defined for the project.
