Mobile Application for Music Catalogs
Closer Music

Content creators, music publishers, and producers need their catalogs where their audience is — on mobile. Our white-label mobile app for music catalogs was built to solve exactly that: a ready-to-deploy Flutter application that brings music libraries to iOS and Android with a professional audio player, playlists, search, downloads, and more.


The Problem

Clients Are Mobile
Customers live on Spotify, Apple Music, and Tidal — but many music businesses are still desktop-first, missing mobile-native users entirely.
Shrinking Platform Revenue
Revenues from big platforms keep shrinking. Diversifying through direct-to-fan channels and cultivating super-fans is no longer optional.
Analog Practices
While other industries embraced digital tools, many music businesses still deal with paper contracts, email chains, and outdated processes.

Features

Audio Player
Built-in media player using iOS/Android native audio services. Background playback, lock screen controls, waveform visualisation, and stem switching.
Playlists
Staff-curated and user-created playlists. Organise, customise, and share collections of tracks.
Advanced Search
Filter by genre, artist, album, duration, mood, theme, BPM, and custom tags. Sort results and apply multiple filters simultaneously.
Favourites
Mark and quickly access preferred songs, albums, or artists. Synced across devices via the backend API.
Downloads
Save music locally for offline listening. Background download manager with progress tracking and storage management.
Sharing
Share tracks and playlists with friends via native share sheets. Deep linking support for direct track access.

Architecture

The app follows a feature-first architecture with clean separation of concerns. Each feature module contains its own UI, BLoC/Cubit state management, repository layer, and models.

White-Label Approach

The app is designed as a white-label product — fully brandable and customisable for different music businesses.

Your Brand
Custom logos, colours, typography, and visual identity. The app looks and feels like your own product.
Configurable
External config file for API keys, environment settings, and feature flags. No code changes needed for basic customisation.
Fast to Market
Expect your branded app published on Google Play and App Store within approximately 4 weeks.
The basic white-label package starts at €8,700 — including the app, marketplace submission for iOS and Android, and initial setup support. Custom features and integrations are scoped separately.

Client Testimonial

Our goal was to build a music platform enabling us to charge our customers in a subscription model and as one-off payments. MusicTech Lab's developers were super engaged. Thanks to their effort, we prepared MVP and started working on the marketing. The first biggest technology milestone was achieved during five months.
