Color Formula Cards

Lost years of formulas when an app locked you out or its sync failed? Color Formula Cards keeps every client's formulas on your phone, with a backup file you own. No account. No subscription. No server that can lose them.

Made for colorists and booth renters who want their client book separate from booking and point-of-sale.

CLIENTS
• Name, phone or email, photo, tags (blonde, vivid, grey coverage…) and your own free-text notes
• Search by name or tag

VISITS
• Date, service (root touch-up, full color, balayage, highlights, toner/gloss, vivid, color correction, cut, treatment, or your own), price, duration, notes
• Before and after photos

FORMULAS
• As many rows as the service needs: zone (roots, mids, ends, all over, custom), line and shade, amount in g or oz, developer volume and amount, ratio, processing time, heat, notes
• Line and shade picker seeded with Wella, Redken Shades EQ, Schwarzkopf Igora, Matrix, Pravana, Goldwell, L'Oréal, Joico, Kenra and Pulp Riot. Type anything else, always
• Copy last formula: one tap brings the client's previous formula into today's visit

THE CARD
• A client's whole history as one scrolling card
• Export everything as a CSV spreadsheet or a JSON file, any time, free
• Export one card as a PDF to share or print (Pro)
• Siri and Shortcuts: ask for a client's last formula, add a card, or export your cards

YOUR DATA, YOURS
• Everything is stored on your phone. Nothing is uploaded, nothing needs a login.
• One tap makes an encrypted backup file you can keep in Files, AirDrop to a new phone, or email to yourself. Restore it on any iPhone.
• Face ID or passcode lock on open.

PAY ONCE
• Free: up to 15 clients, unlimited visits, formulas and photos, backup, lock and CSV export.
• Pro is a single purchase, no subscription, for unlimited clients and PDF cards.

No booking, no payments, no marketing texts. Just the formula book, on your phone.
