About EQ Chart
EQ Chart was built for the moment you just need to handle this task and move on — no signup, no upload to a third-party server. The goal was to keep the path from "open the page" to "get the result" as short as possible. No mandatory account, no cookie wall, no upsell at every step. Like everything else in the utility collection, it is free, ad-light, and works on mobile as well as desktop.
