Tone Caliper
Color-first editing.
Grab the sky. Make it blue.
Pull the blue and the sky deepens — the greens right next to it stay where they are. Nudge as many colors as you like; the photo keeps up as you go.
Color shouldn't be eight sliders.
Fast where it counts. Private by default. Yours to keep.
Your originals stay untouched.
Your originals are read-only — never moved, renamed, or baked over. Every edit lives separately, so you can rework or reset any photo, any time.
Your photos never leave your machine.
No cloud, no account to browse or edit, no telemetry unless you opt in. Point it at a folder and work — everything stays on your computer.
Own it. No subscription.
A one-time purchase, yours to keep. No recurring fees, no seats, no lock-in. The catalog is a single file you control.
Drag. See it. Done.
Move a color and the photo updates as you watch — no lag, no render bar, no waiting for it to catch up. It keeps pace with your hand, every time.

Questions
What is Tone Caliper?
Tone Caliper is a minimal desktop app for photographers: browse your folders, grade by color on one wheel, and keep every change non-destructive. For macOS and Windows.
Does it import or manage my photos?
No. It reads the folders you already have and leaves them exactly as they are — it never moves, renames, or changes your original files. Your edits are stored separately.
Will my photos be uploaded anywhere?
No. Tone Caliper works entirely on your computer. There's no cloud, and you don't need an account to browse or edit.
Is it a subscription?
No. It's a one-time purchase — buy it once and it's yours, with no recurring fees.
