On a phone full of famous apps, the question mark wins.

The real-phone test

F5f, T6b and T6a among the famous

• The "?" owns a category of one. Nothing else on a Home Screen is punctuation — every neighbor is a letter, a house, or a mascot. The tail-question pulls the eye first, even against Home Depot's and Yad2's oranges.
• F5f survives 60 px with all its charm — ears, eyes and drawer handle all legible (see it in the dock too).
• T6b vs T6a: at real size the orange tip disappears — they read identically small; the "cracked mark" issue only exists large. T6a stays the safer form of the same idea.
• iFoundIt is visible bottom-left — the E-family collision, in the wild.

Round 7 — the camera door

Five lens concepts, one real find

Concept-true territory: NoonFox finds things because you photograph them. Five forms of camera-plus-magnifier:

C7b JOINS THE BOARD

The camera that finds things

A white camera whose lens is a knocked-out magnifying glass. The product mechanic in one image: snap it now, find it later. Bold, clean, unique — the round's find.

C7a WATCH

Lens-magnifier

The concentric rings read target-or-vinyl before camera; the rings merge at 29 px.

C7c SKIP

Aperture iris

Pretty, but the iris says "photo-editor app" — wrong shelf in the App Store.

C7d SKIP

Camera with ears

The lens becomes an eye and the whole thing reads "pet cam" — and slightly cat again.

C7e SKIP

Lens with house

The rings read bullseye; together with the house it says "smart-home hub."

How to finish

The board after seven rounds

Leaders: T6a (the mark), F5f (the character), C7b (the product mechanic), with B3a the clarity fallback and T6d/T6c/F5a alive. 52 candidates generated, ≈ $3.90 of $10 spent.
