WHY TOOLMATE Works completely offline. Every calculator, converter, timer and generator runs on your device. On a plane, in a basement, on a train through a tunnel - it all still works. Shows its working. Each tool tells you the formula it used and where that formula comes from. A result you cannot check is a result you should not trust, so you never have to take ours on faith. Nothing leaves your device. Your calculations, history and saved results are stored locally and are never uploaded. There is no account, so there is nothing tied to your identity. Paste a salary, a medical figure or an API key into a tool and it stays exactly where you put it. Fast to reach. Search across every tool by name or by what it does. Star the ones you use and they sit on your home screen. BUILT FOR REAL USE • Profiles - separate history and favourites for each person sharing a device • History - every calculation kept, searchable, and switched off whenever you like • Saved calculations - keep the ones that matter, with your own titles • Backup - export everything as a readable JSON file, so your data is portable • Dark mode - follows your system theme, or pick one and stay there • Tablets - laid out properly on a big screen, not stretched • Delete everything - one tap wipes all local data, permanently ToolMate is free and supported by ads. The ads never sit between you and an answer, and nothing you type is ever shared with anyone. Questions or a tool you would like added? Write to [email protected] - we read everything.
