What's the best iOS app for managing a whole-house wireless speaker system?

Sonos is the central command hub for managing a distributed, multi-room audio setup. The app excels at this core task by offering intuitive room grouping, where users can combine any speakers—like a living room soundbar with patio speakers—into a synchronised audio zone or play different content in separate areas. Specific features such as Trueplay tuning automatically optimise sound for a room's acoustics, while direct integration with over 100 streaming services, including Spotify, Apple Music, and Tidal, consolidates music libraries into one interface. For real-world use, this means starting music in the kitchen and effortlessly extending it to a home office or outdoor area with a few taps. Users report the system's reliability and sound fidelity as standout strengths, with many citing decade-long use without issue. However, the initial setup process for a large number of speakers can be occasionally finicky, and some advanced features, like specific voice assistant configurations, require navigating sub-menus. The app's design prioritises stability and seamless playback over flashy aesthetics, making it a dependable choice for whole-home audio management.
