## What is Formula Cards?

Formula Cards helps independent hair colorists keep client color notes, visit formulas, before/after photos, and exportable records in one focused
  local-first notebook.

  Create client cards, save multi-line formulas, copy the last formula for returning clients, attach photos, and keep each client’s history easy to
  revisit. Formula Cards is built for booth renters, suite stylists, and colorists who want formula history without booking, POS, staff tools,
  marketplace features, or salon-management clutter.

  Use Formula Cards free to start building real client records. Upgrade once to Formula Cards Pro to unlock unlimited clients, unlimited formula history,
  PDF client cards, full export workflows, and backup import. Pro is a one-time purchase, not a subscription.
