## What is Dev Utility Lab?

Dev Utility Lab brings focused developer helper tools into one native iPhone and iPad workspace.

Use it to create a quick checksum, convert decimal/hex/binary values, test simple regex match counts, generate random tokens, estimate IPv4 subnet host capacity, and count words, characters, and lines in text.

Each tool has clear inputs, readable result cards, copy/save actions, and a short local history for recent outputs. The app works offline, requires no account, and keeps common developer scratch tasks available without subscriptions or server setup.
