What's inside
Calculator & productivity
A safe expression calculator (no eval) with history and a scientific mode, plus Timer, Stopwatch, Notes and a Clipboard Manager.

Encoders & decoders
Base64 with file import/export, URL encoding, a local JWT decoder, UUID v4 generator and a Unix timestamp converter.
Regex tester
Live match highlighting and one-click templates for email, URL, IPv4, UUID, dates and more.
Text tools
Word and character counts, case conversion, deduplicate and sort lines, Lorem Ipsum by paragraph or exact character count.
Keyboard symbols
Click to copy ⌘ ⌥ ⇧ → — … € ± ≠ and 150+ more special characters and Greek letters.
