SEND TO Every output has a Send to menu listing the tools that accept it, so an API response goes to the JSON tools, a colour to the gradient tool and an image to the icon generator. Open a file from Files or the Share sheet and the app suggests the tools that read it. FREE AND PRO 43 tools are free and stay free: the quick jobs, every network diagnostic and every reference sheet. One purchase, Pro, unlocks the other 58. No subscription, no packs. Every Pro tool can be tried three times first, and Family Sharing is on. PRIVATE BY DESIGN No account, no server, no tracking. Network access only on your action, and the tools that reach out say what they will do first. The two Apple Intelligence tools run on the device. Built for iPhone, iPad and iPhone Duo, with light and dark mode and Dynamic Type. Requires iOS 18 or later.
