AllTrails Mobile — design system & UI screens

Health & Fitness · 6 screens · alltrails.com

A hiking trail review platform where users share experiences and photos from specific trails. The screen displays user-written reviews with star ratings, trail conditions (terrain, parking, difficulty), timestamps, and image galleries from actual hikes. Multiple user reviews are stacked vertically, each showing avatar, name, rating, metadata tags, review text, and photo carousel.

Decoded design system

AllTrails Mobile's decoded design system: background #FFFFFF, text #000000, accent #94F477, link #94F477, primary #94F477; type scale h1 34px / h2 22px / body 17px; 8px spacing base; 12px base radius. The single interactive/action color is #94F477 — used only on interactive or must-notice elements (buttons, links, key highlights), never on large fills.

Color roles

Role	Value
bg	`#FFFFFF`
surface	`#EFEFEF`
border	`#D8D8D8`
text	`#000000`
text_muted	`#606060`
primary	`#94F477`
accent	`#94F477`
link	`#94F477`
button_bg	`#94F477`
button_text	`#FFFFFF`

Using these colors

Action color #94F477 — the single interactive color; only on things you click or must notice, never large fills.
primary, accent, link, button_bg are all #94F477 — one role, not several (the action color).
accent #94F477 — THE accent / action color — interactive & must-notice only (buttons, links, focus, one key highlight); never large fills or backgrounds. Scarcity is what makes it read as designed.
