For hair colourists
Shadebook
by Dianique
The colourist’s notebook, in the phone.
What it does
Your notebook, as a shade chart
From a notebook page to a formula
Photograph a page, a note or a screenshot, or dictate it — Shadebook reads it into a structured formula with zones, grams, developer and minutes, in English, Polish, Ukrainian or Russian. Every result lands on a review screen before it is saved.
Formulas by zone, in grams or parts
Roots, lengths, ends or your own zones, each with its components, developer percent and ratio. Move the total and every component follows — no calculator.
Timers and what’s left in the bowl
A processing timer per zone that rings on the minute, even in a Focus mode. Note how much was left in the bowl, and the next visit starts from a formula that is already right.
The app, screen by screen
Local-first
Your data stays with you
No accounts and no cloud. Everything lives on the phone, and a backup file goes wherever you keep it — iCloud Drive, Google Drive or a folder of your own.
- No account, no sign-in
- Data on the phone, a backup file you own
- Photos leave the device only when you ask for recognition — and are not stored on the server
- No colour predictions — your judgement, your strand test
Need booking and reminders?
Dianique is our other app: a calendar, client records, online booking and automatic reminders for independent specialists and small studios.
Questions
Color Lab is a module of Dianique: formulas attached to appointments, with material write-off and the rest of a practice around them — calendar, clients, online booking. Shadebook is a standalone formula book for colourists who want only that: no account, data on the phone, formulas by zone in grams or parts, recognition of notebook pages and processing timers. The two apps don’t share data.
The free plan has 10 clients, 30 colourings, unlimited templates and 3 trial recognitions. Pro removes the client and colouring limits and allows up to 100 recognitions a month. Your data is never locked: when a limit is reached you can still read, edit, share and export everything — only adding beyond it needs Pro.
Before-and-after photos stay on your phone, compressed. When you ask for recognition, the photographed page or note is downsized on the device and sent to our server, which passes it to the AI model only to return the structured formula; the image is not stored there — only a usage counter is. Voice is transcribed on the device; only the text is sent.
