Tintwright: Formula Cards

About Tintwright: Formula Cards

Tintwright is a private colorist ledger for salon professionals who need formula cards, visit notes, bowl math, and inventory signals in one offline app.

Save client color history, record line, shade, developer, timing, service context, and follow-up notes. The workbench calculates bowl totals, developer ratios, product cost, and margin from values you enter. A reference library covers practical documentation habits, consultation prompts, correction boundaries, inventory checks, and handoff notes.
