Your painting

In the mirror

The composition looks fine — until tomorrow.

You step back, it looks balanced, you go to bed happy. Next morning it's suddenly obviously off, and you can't unsee it. A mirror check catches this instantly, while you can still fix it — the flipped orientation breaks the familiarity that was hiding the mistake.

How it works

Point your camera at your painting Prop your phone up, or hold it steady, in front of your easel.

Toggle a filter Mirror, Values, Posterize, and Blur each surface a different kind of composition or value mistake.

Freeze and compare Capture a frame to sit with it, or flip back and forth against the plain view.

Everything in the toolkit

—

Mirror flip Flips the live image horizontally — the classic hand-mirror trick, instantly and hands-free.

—

Values Strips out color so you can judge light and dark on their own.

—

Posterize Reduces the image to a few value steps, so value-grouping mistakes jump out.

—

Blur (squint) Simulates squinting at your painting to check the big value masses.

—

Reference photo overlay Upload a reference image, fit it right over your frame, and adjust its opacity and rotation to compare as you paint.

—

Freeze & save Capture a frame to sit with it, then save it straight to your camera roll.

—

Front and back camera Switch cameras without leaving the app, on any phone with more than one.

—

Works as an app Add it to your home screen for quick access — no app store, no account.

Why not just use a hand mirror?

Hand mirror Works for the flip. Can't show you values, and it's one more thing to carry to the easel.
