When Gym Star Simulator was last updated
3 releases observed across 9 daily readings. We watch the update timestamp Roblox itself publishes and record the day it moves — no announcement needed, and it cannot be back-dated.
Full observed release log on the updates page.
Reference tables
Every table names the source its rows came from and the date that source was last read. Nothing here is padded with rows we invented.

Official surfaces and current checks
Where everything on this site traces back to, and when each one was last read by a person.
Official Roblox experience page
Source of record for the player count, visits, favourites, like ratio and the developer's last update time. When anything here disagrees with this page, this page wins.
Gym Star Simulator Wiki (Fandom)
Player-maintained wiki. The pet multipliers, trainer bonuses and world descriptions on this site are compiled from it. It is incomplete — the trainer list documents 5 of the 54 trainers the …
Rolimon's game tracker
Independent third-party tracker, useful for cross-checking the concurrent player figure against our own daily reading.
How this site works
Freshness first
Every figure carries the date it was read. The player counts, visits and codes on this site come from a check that ran on Aug 25, 2026 — not from a page written months ago and quietly restamped with this month's name.
Source hierarchy
Official Roblox data wins. Community wikis are used where nothing official exists, and they are labelled as community on the page that uses them. We never present a player's guess as an official number.
Measured, not copied
The daily player history and the observed release log exist because this site has been reading the game every day and storing what it saw. No other page about Gym Star Simulator publishes them, because you cannot copy a measurement you never took.
Fan-site clarity
Independent and unofficial. Not affiliated with Roblox Corporation or Gym Simulator Club, no payment from the developer, and no paid placements in any table or tier list. Full disclosure.
