Glitch Clock
Read full descriptionHide full description
Hamon turns your screen into a calm pool of water. Tap to drop a ripple and watch it spread, interfere with others, and reflect off the edges — a real fluid simulation, not a looping animation. Switch to ink and stir colors together with your finger: indigo, vermilion and viridian blend the way real ink does in water, then slowly sink and fade. WATCH A living water surface you can touch. Leave it be and ripples appear on their own. CLOCK The time floats on the water, gently distorted by every ripple. Choose a calm water surface or flowing ink behind it. CREATE Adjust the flow — distance, waves, ink density, swirl — and save your own patterns. Designed to be quiet. The interface fades away so only the water remains. No accounts. No ads. No tracking. Everything stays on your device.

Verdict
The clearest difference is in-app purchases: Glitch Clock at none against Widget Tank's 2. Glitch Clock also leads on iOS requirement (17.0 vs 26.2). Widget Tank's advantage is update cadence (every 2 days vs every 10 days). On price, ads and device support there is nothing between them.
