This is a fan-made Stardew Valley reference and planning site: written guides, structured game data, and interactive tools that turn that data into answers. It is a personal project, not a company publication, and it is not affiliated with, endorsed by, or operated by ConcernedApe.
The site exists for one reason. Most Stardew Valley questions are answered in static tables, and a table is a poor answer to "what do I do next in my save". This site keeps the same reference data but pairs it with calculators and trackers: a gift finder that accounts for the season you are actually in, a bundle tracker that shows what is still missing, a fish finder that filters by weather and time, a crop profit calculator that ranks gold per day rather than listing prices, and a Grange Display scorer that returns a real total.
How content is written and checked. Guides are written from the game itself and from the official Stardew Valley Wiki at stardewvalleywiki.com, which is treated as the authority whenever the two disagree. Data pages record the level, item, or mechanic they describe, and pages affected by a game update are revised rather than left to drift. When a correction is reported, the data page is fixed first and the guide text second, so the numbers and the advice do not contradict each other.
What this site is not. It is not a complete copy of the official wiki, and it does not try to be. Coverage is intentionally limited to the tasks the tools support, because a smaller number of accurate, maintained pages is more useful than a large number of thin ones. Pages that only repeated another site were removed rather than filled with filler text.
Corrections are welcome and are treated as the highest priority work. If a number is wrong, the fastest route is the contact page, where an email address and a public issue tracker are both listed.
