About

Keep the last formula ready when your client returns. Save client cards, hair color formulas, client notes and before-and-after photos in one place. Built for independent stylists and colorists working behind the chair. WRITE THE MIX YOUR WAY Record each bowl with brand, line, shade, grams, developer, ratio, processing time and placement. Use the built-in shade catalog, add your own shades or write a formula in your own words. START WITH LAST TIME Open a client's history and repeat their last visit. Adjust the formula for today, save photos and leave a note for the next appointment. Keep your go-to formulas as reusable templates. KEEP CLIENT DETAILS TOGETHER Find clients by name, phone or tag. Keep allergy notes and dated patch test records on the client card. Bring your client list over from Contacts or a CSV file. TAKE YOUR RECORDS WITH YOU Your client records work offline, without an account. Export the whole book as one backup file, keep it wherever you like and restore it on a new iPhone. Automatic daily backup keeps a fresh copy in your own iCloud, next to backups you name yourself. Create client PDFs and share before-and-after photo pairs. Protect access with Face ID.
