## What is HueBook?

Never ask, "What did we mix last time?" again.

HueBook is a private, formula-first client book for professional hair colorists. Keep each client's color history, exact gram weights, processing time, result notes, photos, and next-visit plan in one fast local record.

CLIENT FORMULA HISTORY

- Find a client's latest mix before the cape is fastened
- Record brand, shade, grams, developer, timing, starting level, and target
- Keep allergy notes, service notes, and visit results together
- Add optional before-and-after photos

SCALE A TRUSTED MIX

Change the target bowl weight and HueBook preserves every component ratio. A 60 g formula can become 75 g, 90 g, or any size without mental math or guesswork.

SAVE THE MIXES YOU REPEAT

Turn reliable glosses, root formulas, gray blends, and refresh recipes into reusable templates. Choose a client and start the next record from a proven mix.

BUILT FOR THE CHAIR

- Local processing timers
- PDF formula cards
- Searchable client book
- Portable JSON backup export
- No appointment calendar, payment system, or salon setup required

PRIVATE BY DESIGN

HueBook has no account, no advertising, and no analytics SDK. Client records stay on your device unless you explicitly export or share them.

FREE TO START
