Tracking this channel since . Last updated .
This channel is being tracked. Charts and statistics will build as more data is collected. How these numbers are calculated.
Recovered history: 43 past broadcasts from Twitch's VOD record
Twitch's VOD record has this channel broadcasting as far back as June 18, 2026, 296 hours of airtime in total. Each one has a date, a duration and a title — viewership was not tracked at the time, so there are no viewer figures for them and none are estimated.
StreamerVitals started tracking this channel on August 15, 2026 and holds 1 finalised broadcast and 1 day of observations so far — not yet enough to draw an honest chart. Viewership charts build from that date onwards. How recovered history works.
Every figure below is measured from broadcasts we observed. Percentage changes appear only where the previous period had enough data to compare against.

Times are UTC. Average and peak viewers come from periodic sampling of the live broadcast, so they are close estimates rather than exact platform figures. A stream marked “partial data” had gaps in our sampling; the unobserved time is excluded from its averages rather than filled in.
Rows marked “Archive” come from Twitch’s public VOD record. Date and duration are exact; viewership was not tracked at the time.
