The Method
The 12-season
system, measured.
Personal color analysis used to mean a stylist, a $300 in-person session, and a week of waiting. Tonebook brings the same framework — Spring, Summer, Autumn, Winter, four sub-seasons each — into a 60-second AI analysis, calibrated against thousands of labeled portraits.
01
portrait · neutral light
Step one
A single selfie.
Front-camera, natural light, no filter. The app guides you through framing in under 20 seconds.
02
Step two
Undertone, isolated.
We sample skin under three light models to separate true undertone from ambient cast. Warm, cool, or neutral — measured, not guessed.
03
Step three
Your season, located.
Twelve cells, one match. We place you on the wheel — Soft Autumn, Cool Winter, Light Spring — with confidence intervals shown.
04
Step four
A palette, yours.
Twelve curated colors for clothing, makeup, hair — exportable, shoppable, swatched against the brands you already wear.

Proof
Two thousand
people, on record.
Tonebook isn't a quiz. The reviews on the App Store reflect that. We don't borrow press logos until there's real press to borrow — only photos, names, and the season people got.

Why Tonebook
The case for
measurement.
We're not the only color app. We're the one that doesn't guess.
01 — Accuracy
Free five-minute quizzes guess. Tonebook measures.
We sample real pixels under modeled light. Quizzes ask you to self-rate vein color in your kitchen.
02 — Speed
$300 in-person consults take a week. Tonebook in 60 seconds.
Same 12-season framework, calibrated continuously against new portraits. No appointment, no driving.
03 — Personal
Pinterest boards are someone else's palette. Yours is yours.
Twelve curated colors based on your actual undertone — exportable to your shopping list, your closet, your camera roll.
04 — Built for iOS
Designed for the iPhone you already own.
On-device pre-processing, secure cloud analysis, no account required to start. No web upload, no third-party trackers.
Common questions
Asked, plainly.
Answered, plainly.
Ordered by what people actually worry about, not by what we'd like to lead with.
Q · 01
Do my photos leave my phone?
Pre-processing is on-device. Only the cropped face crop and the derived color samples are sent to our servers, encrypted in transit and at rest. We retain your selfie for 30 days for accuracy auditing, then delete it. You can delete it sooner from Settings → Data.
Q · 02
Are my photos used to train AI?
Not without explicit opt-in. The training-data toggle is off by default, lives in Settings → Privacy, and you can revoke consent at any time. Opted-in photos are anonymized and stripped of EXIF metadata before they reach any training set.
Q · 03
How accurate is the season placement?
Tonebook agrees with certified human analysts ~92% of the time on the 12-season grid, and within one neighboring sub-season ~98% of the time. Each result ships with a confidence interval, and you can request a re-analysis with a new selfie at any time on Plus.
Q · 04
What's free vs. Tonebook Plus?
Free: one full analysis, your season, and a 12-color palette. Plus ($24.99/year): unlimited re-analysis, deeper makeup and hair guidance, palette exports, in-store shopping mode (camera matches an item to your palette in real time), and seasonal wardrobe planning.
Q · 05
Can I refund Plus?
Yes — refunds are handled by Apple at reportaproblem.apple.com. Apple's standard policy is generous within 14 days of charge.
Q · 06
Which devices and skin tones are supported?
iPhone XS and newer, iOS 16+. The model is trained on a deliberately diverse dataset spanning Fitzpatrick I–VI; if you ever feel your placement is off, send the analysis ID to support and we'll route it to a human reviewer.
Q · 07
Will there be an Android version?
Not on the v1 roadmap. We're focused on getting iOS exactly right; Android is on the table for late 2026 if demand justifies the parallel calibration work.
