Peak Guide is a mobile app built for hikers, mountaineers, and volcano enthusiasts who want to explore the world's most dramatic summits from their phone. It combines an interactive map, curated peak data, and AI-powered tools into a single dark-themed interface designed for serious outdoor planning. Whether you're researching Cotopaxi's glacial hazards from your couch or logging a live ascent on the trail, the app keeps everything in one place. It's aimed at anyone who treats mountains and volcanoes not as backdrops, but as destinations.

App in Action

What's Inside

Peak Guide centers on a world map populated with mountain and volcano markers — peaks like Aconcagua, Annapurna I, Denali, Ben Nevis, Eyjafjallajökull, and Anak Krakatau appear as color-coded pins, with teal icons for mountains and red for volcanoes. Tapping a peak pulls up a dedicated page with elevation in both metric and imperial units, regional context, an overview, and interesting facts. The entry for Cotopaxi, for example, notes that it sits at 5,897 m (19,347 ft) in the Andes, that its near-perfect cone is visible from Quito on clear days, that glacier travel and sudden weather define summit attempts, and that major lahars from its 2015 eruptions closed the national park for years.

Planning Tools and AI Integration

Beyond browsing, Peak Guide lets users add their own peaks. The "Add peak" form asks for a name, type (Mountain or Volcano), and a pin dropped on the map. From there, users can fill in details manually — elevation, region, description — or trigger an AI assist that calls OpenAI to populate elevation, region, overview, notable climbers, history, flora, and fauna automatically. This feature requires cloud AI to be enabled in Settings and a personal API key, which adds friction for users unfamiliar with API configuration. The app also includes an Ascents tab and a Live ascent mode with GPS positioning for tracking climbs in real time.

Design and Accessibility

The interface runs on a dark theme throughout, which reduces eye strain and suits low-light field conditions. Information is structured clearly — section headers, elevation figures in large type, and consistent navigation with back arrows, close buttons, and bottom tabs. Apple Maps provides the underlying cartography, with teal and green terrain coloring. That said, the color-coding system (teal vs. red icons) lacks supplementary text labels, which creates potential issues for color-blind users. The heavily stylized orange promotional headers — bold, outlined, shadowed — can also be difficult to parse for screen readers, and small map markers may be challenging touch targets for users with motor impairments.

Visual Identity

The app's promotional screenshots lean hard into a dramatic volcanic aesthetic: photorealistic 3D lava spheres with glowing orange cracks float against deep blue, star-scattered skies, framed at the bottom by tropical palm fronds. It's a mood that echoes the fiery reel imagery found in volcano-themed slot games — where molten cores, ember showers, and deep-red atmospheric gradients are used to signal heat, danger, and spectacle. Peak Guide borrows that same visual grammar, using it not to promise wins, but to capture the raw, elemental draw of active summits.

Peak Guide's AI assist is genuinely useful for building out custom peak entries, but requiring a personal OpenAI API key limits that feature to a narrower audience than the app's general premise suggests.

Peak Guide Explained

What kinds of peaks does Peak Guide cover?
Peak Guide covers both mountains and volcanoes worldwide, from well-known summits like Aconcagua, Denali, and Annapurna I to active volcanoes like Cotopaxi, Anak Krakatau, and Chimborazo. Each peak is displayed on an interactive map and includes an overview, interesting facts, elevation, and regional information.
How does the AI gear suggestion feature work?
Peak Guide uses AI to provide gear suggestions tailored to your planned climb, helping you prepare smarter for each summit. The app also offers an AI assist tool when adding a new peak, which can automatically fill in elevation, region, overview, notable climbers, history, flora, and fauna via OpenAI — this requires cloud AI to be enabled in Settings along with an API key.
Can I add a peak that isn't already in the app?
Yes, you can add a custom peak using the Add Peak form — just name it, choose whether it's a mountain or volcano, and drop a pin on the map to set its location. You can fill in the details manually or use the AI assist button to auto-populate the information.
How does ascent tracking work in Peak Guide?
Peak Guide includes an Ascents tab and a Live Ascent tab accessible from the bottom navigation bar, allowing you to log and track your climbs. The Live Ascent feature uses location and navigation tools to follow your progress in real time.
In what units does the app display elevation?
Elevation is shown in both metric and imperial units simultaneously — for example, Cotopaxi is listed as 5897 m • 19347 ft. This makes the data accessible to climbers regardless of their preferred measurement system.
