About
Your client formulas deserve better than an index card box, or an app that logs you out and loses everything.
Formula Log is a private client and formula log for colorists. Everything lives on your phone. No account, no login, no server holding your work hostage.
DATA THAT STAYS YOURS
Formula, toner, processing time, price, and notes -- write it exactly how you'd write it on a card. Back up anytime and restore on a new phone without losing a thing.
EVERY CLIENT, A-Z
Search by name or formula. See each client's full visit history in one place.
BEFORE & AFTER
Attach a photo before you start and one when you're done. Drag to compare them side by side, right on the client's card.
TODAY'S CLIENTS
Open the app and see who's due back, what you earned this month, and your recent formulas.
NO SUBSCRIPTION
Pay once. Formula Log is yours forever -- no monthly charge, no renewal, no losing access if you stop paying.
Export your full client list and formulas to CSV or JSON, anytime. It's your data.

What's New in Formula Log
1.0.1
September 4, 2026
Your purchase now sticks. If you had paid and the app ever asked you to pay again — offline, or after reinstalling — it will not do that any more. The Backup screen now tells you the truth about where your work is: when it last saved, and if anything is stopping it. Plus a set of fixes to make sure nothing in your book can be removed without you doing it.
