General & daily utilities

21 free everyday tools: stopwatches and timers, a world clock and time zone converter, date and work calculators, a printable calendar, random and team generators, a decision wheel, barcode tools, Wi-Fi QR codes, validators, a public IP lookup, a speed test, password strength and file hashing.

Note: Almost everything runs entirely in your browser — nothing is uploaded. The public IP lookup and internet speed test use free public APIs (ipify, ipwho.is and Cloudflare) and the only data sent is the request needed to fetch your address or the test file.
