White Nightmare
Read full descriptionHide full description
Simple! Find the pure white color blocks. It is very hard, you hard to see which one is true white color.
Knotless
Read full descriptionHide full description
Knotless is a small app where you simply tap glowing knot tiles and watch them turn. There are no rules. No scores. No ads. No words on the screen. Tap a tile, and the strand changes direction. Tap again, and the colors shift. The pattern feels like it is almost tangled, almost untangled, always moving. Knotless is not an app for achieving anything. It is just something to tap.

Verdict
The clearest difference is ads: Knotless at none against White Nightmare's shown. Knotless also leads on update cadence (every 4 days vs every 16 months). White Nightmare's advantage is price ($1.99 vs $3.99) and iOS requirement (15.6 vs 18.0). On in-app purchases and device support there is nothing between them.
