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 price: Zen Lines at Free against Knotless's $2.99. Knotless's advantage is update cadence (every 4 days vs every 2 months). On ads, in-app purchases, device support and iOS requirement there is nothing between them.
