## What is HolderLog?

HolderLog is a one-time-purchase tool holder manager for small machine shops. Put a QR tag on every holder, and a scan at the machine shows the gauge length, offset notes, and remaining tool life in large type - readable with gloves on.

SCAN AT THE MACHINE
No more walking back to the crib or squinting at a paper setup sheet. Scan the holder, read the numbers, enter them, cut.

TOOL LIFE METER
Every holder carries a life limit in minutes. Add usage with one tap (+10 / +30 / +60 or custom) after each job. At 80% the holder turns amber; at 100% it turns red. Worn tools stop sneaking back into the spindle.

TOOL CHANGES
Record regrinds and replacements, optionally resetting the usage counter. The change history stays with the holder.

PROVEN CUTS
Save "this worked" notes per holder and material - speeds, feeds, and anything else worth remembering - and pull them up at the next setup.

SETUP SHEETS
Group holders into jobs and export a setup sheet PDF listing every holder with its numbers. Print QR label sheets (A4) for the holders themselves.

UNITS
Work in mm or inch - values are stored consistently and converted exactly.

BACKUP
File-based backup and restore. A failed restore never touches existing data.

WHO IT'S FOR
CNC operators, setup people, and owners of small machine shops.

PAYMENT
One-time purchase. Every feature is included. No subscription, no in-app purchases, no account, and no data leaves your device.
