Stella Sora Global launched on Android, iOS and the Windows official launcher on October 19, 2025 at 19:00 (UTC-7). Steam is a later release: at the October 19, 2026 check, its English/US listing still showed a planned October 19, 2026 date and said the game was not yet available. A displayed release date is not confirmation of an unlock.
Global release history and dated Steam schedule. No exact Steam unlock hour or completed anniversary maintenance is inferred from an approximate countdown.

The official launch notice explicitly names Android, iOS and the Windows official launcher. Its October 20 article date and an October 19 server-time launch can refer to the same release event; do not move the Global launch to 2026 because Steam has a later storefront date.
Steam remained in planned-release status at the check
The captured US Steam response lists coming_soon as true with October 19, 2026. The current bare English store reading also says the game is not yet available and displays an approximate unlock countdown. Another supplied browser capture displays October 20. Keep the storefront context with the date rather than treating those calendar labels as two different game launches.
The approximate countdown does not establish an exact universal release time. Open the actual Steam listing to see whether an installation action has appeared for your region and account. This reference records the checked state; it does not claim that the planned date means the game was already playable.
Anniversary content has its own maintenance condition
The version 2.0 preview schedules anniversary content after the October 19, 2026 maintenance, with individual activities ending on different dates. That announcement is separate from the original mobile/launcher launch and from Steam’s observed unlock state. An announced after-maintenance start is not proof that the maintenance has completed.
The PC client guide distinguishes the existing launcher from the scheduled Steam client.
