Android & iOS apps,explained end to end.

What mobile app development covers

A mobile app is more than the screens on a phone. A real product usually consists of three parts: the app itself (Android and/or iOS), a backend that stores data and runs business logic (user accounts, orders, payments, notifications), and an admin panel where your team manages content, users and reports.

We plan all three together so that the app is fast, secure and easy to extend. Whether you need a simple information app, a booking app for your salon, a delivery platform with customer, driver and restaurant apps, or an internal field-force app for technicians – the process below applies.

Android runs on roughly 70% of smartphones worldwide and around 60% in Germany; iOS users tend to spend more in apps. Most businesses therefore launch on both platforms – which is why choosing the right technology approach is the first big decision.

Choosing the right approach

There is no single best technology – it depends on your features, budget and timeline. This comparison helps you decide:

App segments – what kind of app are you building?

Apps fall into segments with typical features. Knowing your segment makes planning and estimating much easier.

Mobile game segments

Games are a segment of their own with different tools (game engines) and business models. Our Game Development guide goes deeper; here is the overview for mobile:

Google Play & App Store categories

When you publish, the app must be placed in an official store category. It influences search visibility and which review guidelines apply.

Common feature building blocks

Most apps are combinations of proven building blocks. Ticking the ones you need is a great first step for your brief:

• User accounts: email/phone login, Google/Apple sign-in, roles and permissions, profile management
• Payments: Stripe, PayPal, Klarna, Apple Pay / Google Pay, in-app purchases & subscriptions
• Maps & location: live tracking, geofencing, address autocomplete, distance-based pricing
• Notifications: push (Firebase Cloud Messaging / APNs), in-app messages, email & SMS
• Communication: chat, voice/video calls, file sharing
• Device features: camera, QR/barcode scanning, NFC, Bluetooth, biometrics, sensors
• Offline mode: local database (Room, SQLite, Hive) with background sync
• Content & admin: CMS, admin dashboard, reports and exports
• Analytics & quality: Firebase Analytics, crash reporting, A/B tests, performance monitoring
• Localisation & accessibility: multiple languages (DE/EN), dark mode, screen readers, large text

How we develop your app – step by step

This is the exact workflow we follow. Each step ends with something you can see and approve, so there are no surprises.

1. Discovery & requirementsWorkshop (call or in person near Munich) to understand goals, users, features and constraints. We sort features into Must-have, Should-have and Later.Deliverables: requirements brief, feature list, rough estimate
2. Technical concept & architectureWe choose native or cross-platform, define the backend, APIs, data model, third-party services and hosting, and plan security and GDPR aspects.Deliverables: architecture diagram, tech-stack decision, fixed quote
3. UX: user flows & wireframesWe map every journey (onboarding, ordering, payment…) as clickable wireframes so you can test the logic before any design work.Deliverables: user-flow map, clickable wireframes
4. UI designVisual design in Figma following your brand, Material Design 3 (Android) and Apple Human Interface Guidelines (iOS), including dark mode and accessibility.Deliverables: Figma designs, design system, interactive prototype
5. Agile development in sprintsTwo-week sprints for app, backend and admin panel. After every sprint you install a test build on your phone (TestFlight / Firebase App Distribution) and give feedback.Deliverables: test builds every 2 weeks, sprint demo
6. Testing & quality assuranceFunctional, regression, performance and security testing on real Android and iOS devices of different sizes and OS versions; automated unit and UI tests for critical flows.Deliverables: test report, bug-free release candidate
7. Store publishingWe prepare store listings (texts, screenshots, privacy labels, data-safety forms), handle Google Play and App Store review and fix any reviewer feedback.Deliverables: live apps in Google Play & App Store
8. Launch, monitoring & growthCrash and performance monitoring, analytics dashboards, App Store Optimisation (ASO) and a roadmap for the next features.Deliverables: monitoring dashboard, release roadmap
9. Maintenance & updatesYearly OS updates (new Android/iOS versions), security patches, library upgrades and new features under a support plan.Deliverables: SLA-based support, regular updates

What drives the cost and timeline

We give a fixed quote after the technical concept. These factors have the biggest impact:

What we need from you to start

• A short description of the idea and who will use the app
• The most important features (a rough list is enough – our AI assistant helps you build it)
• Examples of apps you like or competitors
• Your brand assets (logo, colours) if available
• Accounts we will set up together: Google Play Console, Apple Developer Program
• A decision maker for weekly feedback during development
