Question. Which small symbol would make the completed app concept recognisable on an iPhone, without suggesting it is an official airport service?

I am developing the icon after the brand goal, mascot and app layout so it can summarise the identity rather than determine it. Apple’s app icon guidance stresses a simple, recognisable composition that works at small sizes. Xcode’s app-icon guidance also describes light, dark and tinted appearances. An icon needs to work on a home screen among other apps; the app’s detailed ticket UI does not belong inside it.

Looking at other app identities

I compared the official Heathrow app listing, Schiphol app listing and Finch listing. The airport products are identified by their place and service; Finch centres its companion in the product name and imagery. Schiphol's listing also records an appearance setting that lets a user change its app-icon colour. These examples raise a question for my icon: should it signal wayfinding, personality or a combination? Their listings do not tell me which icon autistic travellers would recognise most easily.

The earlier local route-point icon study used a navy field, white path and peach dot. It suggested wayfinding but was generic against the later lilac/lime system. This is process material, not the selected mark. The mascot references on Page 08 show how a face can be memorable, but a face alone might lose the journey idea.

First alternatives

The three current options deliberately vary the centre of recognition:

• Route point: quick connection to travel, but visually close to common map/navigation marks.
• Face: directly companion-led, but may appear like a mood or wellbeing app.
• Open-loop mascot: keeps the irregular original silhouette, a small expression and a route-like opening.

These are vector studies on neutral ground, without extra labels inside the artwork. The comparison asks whether someone can identify the mark when shrunk, not whether the large illustration is attractive.

Provisional candidate

The open-loop icon is the present candidate because it connects the app to the original mascot and the repeated journey curve. Lime stands out against charcoal while the lilac element ties back to the app. This is a design interpretation, not a measured recognition result. The dark field also helps keep the icon legible without turning the entire home-screen icon into a pale UI screenshot.

I still need to inspect it at actual small icon sizes, next to comparable travel apps, in light/dark/tinted iOS appearances and with people who have never seen the project. The cheek, eye and loop opening may become too fine. The icon must not carry any safety or status meaning; the app name and the alert text do that work.

Taking forward — provisional: the loop candidate for further testing. Only after size, recognition, accessibility and name checks should it be treated as the final brand icon.
