Toner: Hair Color Formulas app analytics for September 3

Your formulas are your paycheck. They deserve better than a subscription, a login screen, and somebody else's server. Toner is the client card box, digitized: pay once, own it forever, works with zero signal — and nothing you write ever leaves your phone. Every client gets a card: her formulas exactly as you write them — line, shades, developer, ratio, timing — with photos of the result, her allergy and patch-test record, and every visit with its price. NO SUBSCRIPTION. NO ACCOUNT. NO LOGIN BETWEEN YOU AND YOUR 3:00. REPEAT LAST VISIT — her standing formula becomes today's ticket in two taps. Adjust a shade, save, mix. Five-week root clients take zero typing. SEARCH LIKE A COLORIST — "Who gets 7NB?" "Every Shades EQ gloss I've done." Type a shade code, a product line, or a name — every matching head, instantly. Paper cards and the Notes app can't answer that. AN UPDATE CAN NEVER DELETE YOUR BOOK — your cards live on your phone, not on a server that can migrate badly. And your book is never hostage: export any client's card as a clean PDF, or your whole book as a spreadsheet, anytime. NEW PHONE, FULL BOOK — back up everything — clients, formulas, photos — as a single encrypted file only your passphrase can open. AirDrop it to your iPad, drop it in Files, email it to yourself. Restore in one tap. No account required, because your book shouldn't need permission to survive a lost phone. ALLERGIES FRONT AND CENTER — sensitivity notes and patch-test history sit at the top of the card and on every new ticket. The information that matters most is impossible to miss. PRINT HER CARD — a clean, professional PDF of any client's full formula history. For the station binder — or the classiest goodbye in the industry when a client moves away. Levels, vol and %, 1:1.5 — Toner speaks fluent colorist and never autocorrects a formula. 7NB stays 7NB. One price. Every future update included. Your book, your property.
