See any image the way a painter does. Bring in a reference photo, a master painting or a screenshot. In seconds, Undertone shows what sits underneath it: the values, the warm and cool, the composition and the real pigment colors. The things a painter checks before the first brushstroke, made visible. All processing happens on your device. Your images never leave it. Value study. The image stripped to grayscale and divided into clear tonal zones. Two values give you a notan, three give you light, middle and dark. Value does more work than color: a painting with strong values and wrong colors still reads. This automates the painter's squint. Composition. The structure under the image, from the rule of thirds and the golden ratio to triangles, leading lines, symmetry and framing. Ten types, and Undertone only shows the ones the image actually follows, each with how closely it matches. Premium. Warm and cool. A temperature map over the image. Muddy shadows? Probably warm paint leaking into your cools. Golden hour? Warm light forces cool shadows by contrast. Toggle the map on, and what you couldn't diagnose becomes obvious. Palette with real pigment names. Dominant colors shown by actual weight, each matched to the closest real pigment. Yellow Ochre, not "Autumn Sunset Dream." Undertone names the closest harmony and plots the colors on a wheel so you see the geometry. Saturation. Vivid areas glow, muted areas recede. See whether the intensity sits where you want the eye to go. Contrast. Where the eye lands first. Rings mark the strongest areas. Premium. Made for painters and artists: studying a master painting, planning a piece from a reference photo, or finding out why the shadows went muddy. Photographers use it to understand why a light works so they can find it again. Every analysis is saved, and over time your history becomes your own color reference. Free: 20 analyses at a time with the Original, Temperature, Values and Saturation modes, plus the palette and harmony for every image. Premium: Composition (10 guide types), Contrast, tinted value bands, the 2-value notan and 2 to 9 tonal steps, unlimited history, higher-resolution export. One-time purchase. No subscription. Stop guessing. Start seeing.

Verdict
The clearest difference is in-app purchases: SnapspaceAi at none against Undertone's 1. SnapspaceAi also leads on update cadence (every 2 days vs every 10 days). On price, ads, device support and iOS requirement there is nothing between them.
