App development Berlin

An app is more than a screen: audience, store rules, budget, who owns content later? We clarify that before coding—so you do not discover three months in that the chosen path costs more than planned.

Consulting:

We look at what the app must do, what data moves, and whether an iOS/Android listing is mandatory or a PWA is enough. Then we propose React Native, web, or a mix—with an honest view of cost and timeline.

Strategy:

Roadmap means MVP, then measure. We plan releases so you get early feedback from the store or the web channel—not a year of silent building.

Typical topics: React Native vs web-only, monetisation (in-app, subscription, free), analytics, and which APIs you already have. We say what has worked—without cramming every feature into v1.

After launch we stay available for analytics, small features, and OS updates. Mobile keeps changing; the app should be able to keep up.

Every idea needs a stack that fits budget and roadmap. Together we decide: store app with React Native, web-only, or both—instead of tech for tech’s sake.

Cross-platform with React Native

One codebase for iOS and Android keeps features in sync and usually costs far less than two fully native teams. iPhone and Android builds stay aligned.

We use React Native where native modules matter (camera, push, in-app purchases) while sharing most UI. Updates go through the stores; we test on real devices, not only simulators.

Progressive web apps (PWAs)

When the app store is optional, PWAs can be enough: installable, offline where it makes sense, often faster to iterate.

Offline, push (where browsers allow), home-screen icon without store approval

One build for desktop and mobile browsers—strong when users mainly arrive via the web

Web app development

Dashboards, marketing sites, and admin UIs use React and Next.js—the same mindset as React Native so components and types line up.

SPAs where it fits; server rendering when SEO and first load matter

Layouts that hold from small phones to large desktops

Backend & APIs

Apps run on data. We plan integrations with your CRM, shop, or custom backend so failures show up in logs—not only for end users.

Hosting is usually AWS, Google Cloud, or Azure—often whatever you already use

REST or GraphQL, depending on complexity and team

SQL or NoSQL—what fits volume and queries

Payments, maps, auth: connect instead of building islands

Technology per project, not per hype cycle

We also say no to features that blow the first release. A stable MVP and measurement beats a bloated v1.

Our focus: React Native for iOS/Android apps, React/Next.js for web and PWAs. We are practised there—instead of sampling every framework once.

Apps rarely fail on typography—they fail when the next step is unclear. We fix hierarchy, empty states, and errors before pixel-perfect polish.

Users first

We clarify who actually uses the app (and who never opens it) early. Wireflows and priorities follow from that—not the other way around.

Wireframes & prototypes

Clickable prototypes show whether flows work. Better to rethink in the prototype than in production.

Look & design system

Colour, type, and components follow your brand and iOS or Material patterns where it helps—so nothing looks “almost Apple” but confuses people.

From small phones to tablets

We break layouts sensibly; thumb reach and readability beat exotic animation.

Testing

Short tests with real users surface issues the team no longer sees.

Design and engineering sit together: what we sketch can be built in React Native—no week-ten surprise.

Tech alone is not enough: without a searchable listing that explains the app at a glance, downloads stay low. ASO is the lever—for Apple App Store and Google Play.

Keywords

We research what people actually search for and place terms in title, subtitle, and description—following each store’s rules.

Icon, screenshots, video

First impression in the store: we sharpen visuals and screenshot order; we test variants where it helps.

Ratings

Stars and text affect trust and ranking. We help collect feedback fairly and reply professionally.

Localisation

More countries need more than literal translation: character limits, search terms, and tone per market.

Measure & iterate

We compare listing data and competitors regularly; ASO does not end at first upload.

Goal: more organic installs and clearer expectations for people who actually download.

After go-live comes operations: new OS versions, store policy changes, bugs under load. We keep builds current or support your team—depending on the agreement.

Reliability

We fix crashes, slow APIs, and server timeouts at the source—with logs and targeted fixes instead of symptom-only patches.

Security

Dependencies, auth flows, transport: we schedule updates before they become emergency calls.

iOS & Android

Apple and Google change the rules every year (permissions, push, store policies). We test against betas where it makes sense so release day is not surprise day.

Features from data

What to build next can come from usage and feedback—not only from the longest feature list.

Monitoring & analytics

Metrics show where users drop off or which API struggles—that drives concrete next steps.

An app is software with a shelf life; we help make sure that date is not tomorrow.
