Granite is an encyclopedia of New Hampshire’s 48 four-thousand-foot peaks.
Each entry goes beyond the trailhead. Granite covers the geology that shaped each summit, the history embedded in its name, the ecology of its alpine and subalpine zones, and the live weather forecast pulled directly from the National Weather Service. This is a reference app built for people who want to understand the mountains they are standing on – or planning to stand on.
Mount Washington and The Land are free. One purchase unlocks the other 47 peaks, the Mount Washington Deep Dive, The Rock Beneath It All, and summit record export. No subscription. No recurring charges. Buy it once and it's yours.
WHAT'S INSIDE EACH ENTRY
- Summit elevation and coordinates
- Two views of every peak: a USGS topographic map and 3D shaded relief
- Mount Washington's USGS map tiles are built into the app, so the free peak's maps open right away
- Tap the coordinates to open the summit in Apple Maps
- Geology – bedrock type, glacial history, how the summit took its shape
- Name history – the origin of every peak name
- Ecological notes on treeline, krummholz, and alpine plant communities
- Live summit forecast updated hourly via the NWS gridded forecast API, with a link to the Mount Washington Observatory's Higher Summits
Forecast on Presidential peaks
THE ROCK BENEATH IT ALL
A plain-language guide to what the White Mountains are made of: the ocean floor that became metamorphic rock, the collision that raised the range, the rift that never quite happened, and the ice that carved the shape you see. It ties together the rock names that appear across all 48 entries.
THE LAND
How the White Mountains became what they are: the logging that stripped the forest, the Weeks Act of 1911, and the creation of the White Mountain National Forest. Free for everyone, with sources listed in Settings.
MOUNT WASHINGTON DEEP DIVE
Mount Washington's entry goes further than any other peak in the app. The Cog Railway gets a full history and complete locomotive roster, from Sylvester Marsh's original 1869 ascent to the mixed steam-and-biodiesel fleet running today. A separate chronology traces the mountain itself through to today's wind records and visitor counts – researched and checked against multiple sources, not scraped or templated.
SUMMIT SEALS
Mark a peak as climbed and earn a summit seal – bronze, silver, or gold. The first sixteen summits result in a bronze seal, the next sixteen makes them silver, and once you start on the final sixteen they all turn gold. The order doesn't matter. Your record stays on your device and, if you use iCloud, syncs between your own devices. It is never sent to the developer.
Once you've started building your record, export it as a PDF – a dated record of every peak you've climbed, ready as a reference when you're applying to the AMC Four Thousand Footer Club.
THE PRESIDENTIAL RANGE
All nine peaks in the Presidential Range group are included – Washington, Adams, Jefferson, Madison, Monroe, Eisenhower, Pierce, Jackson, and Isolation – with full entries for each. Each Presidential entry links to the Mount Washington Observatory's Higher Summits Forecast, so the Observatory's own forecast for the most exposed ridge in the northeastern United States is one tap away.
THE SANDWICH RANGE, CARTER-MORIAH RANGE, AND BEYOND
Granite covers all 48 peaks across every range in the White Mountains – from the remote summits of the Pemigewasset Wilderness to the Sandwich Range peaks that rise above the Swift River Valley. Remote, rarely climbed summits get the same depth as the well-traveled Presidential giants.
BUILT FOR THE MOUNTAINS
Granite was designed and written for people who take these peaks seriously. The entries are substantive and the weather is live. There are no ads, no tracking, and no data is collected from your device.
