Notes. Source: Sensor Tower API (Store + Usage Intelligence). MAU = worldwide iOS + Android monthly active users, quarter-end month.
Downloads = worldwide Sensor Tower unified downloads (iOS + Google Play, summed across all countries) — the same definition
as Sensor Tower's unified app view. Time spent = average minutes per user per week,
US only (Sensor Tower does not publish worldwide session metrics), blended across iOS/Android weighted by US MAU — this measures
foreground app usage, so background audio playback is not counted. Spotify "Reported" = company-disclosed MAU from quarterly
earnings; 2Q26 not yet reported. Sensor Tower panel estimates typically run above Spotify's reported base at the level, but net-add
deltas track reported net adds closely. Suno's mobile app launched July 2024 (Android later) — quarters before 3Q24 are blank. Udio's iOS app launched May 2025 and has no Android app; quarters before 2Q25 are blank, and its worldwide time spent ≈ US (US-dominated panel sample).
Worldwide time spent = the same metric aggregated by Sensor Tower across its full ~108-country panel (ex-China), MAU-weighted
across iOS/Android; ST has no single "WW" region for session metrics, so this is the standard workaround.
