Hydrolyze App Icon Stroke-Weight Correction — 2026-06-30

> User signal (verbatim): "I think the stroke line on the waterdrop needs more weight. it looks too fragile at the moment, it needs to stand out more." (2026-06-30)

The Hydrolyze brand already has a precedent: the v1.16 microinteraction push explicitly added StrongPressFeedbackStyle (a scale-down 0.92 on press) and increased cyan glow opacity because the previous "lightweight" treatment wasn't felt at the pool deck. Same instinct: light/digital feels wrong for a physical, serious context (5am pool, professional tool, deadline-driven timing).

The user's two-word diagnosis: "too fragile." The fix: heavier stroke + heavier colon dots, scaled so the icon reads at the home-screen size (where it lives most of the time) AND survives pixel quantization at 40px notification (where it's smallest).

Stroke 22 and dot r=52 keep the icon balanced — at 180px home screen the drop's edge is 3.9 effective px (was 2.4), the dots are 18 effective px each (was 16), and the colon still reads as a colon rather than as a single filled blob.

How it's structured

Why this is a class-level preference signal The reduction is consistent: "weight conveys authority and presence" is a recurring Hydrolyze design preference, not a one-off icon ask.
The trap to avoid > Don't default to thin. Every icon in tech-brand space inherits the swiss-modern instinct (thin strokes, hairline weights, geometric pu…
